step by step 之餐飲管理系統(tǒng)五(Util模塊)------附上篇日志模塊源碼這段時間一直在修改日志模塊,，現(xiàn)在基本上寫好了,，也把注釋什么的都加上了，昨天郵件發(fā)送給mark的園友一直報失敗，老是退回來,，真是報歉,，如下圖所示： 沒有辦法,，只好放這里了,，想看源代碼的請猛戳這里 如果有什么問題，歡迎跟我交流,！ 從今天開始寫Util模塊,，這個模塊幾乎所有的系統(tǒng)項目都需要的，想減少重復(fù)代碼的編寫,，就依靠這個模塊了.大的模塊主要是以下幾個方面： 1.加解密 這個我也不多說了,，也就是MD5等加密算法:  using System; using System.Security.Cryptography; using System.Text; /// <summary> /// 加解密相關(guān)操作類 /// </summary> /// <date>2012-02-20</date> /// <author>xucj</author> public class Cryptography { private const string DefaultKey = "OD"; /// <summary> /// 構(gòu)造方法 /// </summary> public Cryptography() { } /// <summary> /// 使用缺省密鑰字符串加密 /// </summary> /// <param name="original">明文</param> /// <returns>密文</returns> public static string Encrypt(string original) { return Encrypt(original, DefaultKey); } /// <summary> /// 使用缺省密鑰解密 /// </summary> /// <param name="original">密文</param> /// <returns>明文</returns> public static string Decrypt(string original) { return Decrypt(original, DefaultKey, System.Text.Encoding.Default); } /// <summary> /// 使用給定密鑰解密 /// </summary> /// <param name="original">密文</param> /// <param name="key">密鑰</param> /// <returns>明文</returns> public static string Decrypt(string original, string key) { return Decrypt(original, key, System.Text.Encoding.Default); } /// <summary> /// 使用缺省密鑰解密,返回指定編碼方式明文 /// </summary> /// <param name="original">密文</param> /// <param name="encoding">編碼方式</param> /// <returns>明文</returns> public static string Decrypt(string original, Encoding encoding) { return Decrypt(original, DefaultKey, encoding); } /// <summary> /// 使用給定密鑰加密 /// </summary> /// <param name="original">原始文字</param> /// <param name="key">密鑰</param> /// <returns>密文</returns> public static string Encrypt(string original, string key) { byte[] buff = System.Text.Encoding.Default.GetBytes(original); byte[] kb = System.Text.Encoding.Default.GetBytes(key); return Convert.ToBase64String(Encrypt(buff, kb)); } /// <summary> /// 使用給定密鑰解密 /// </summary> /// <param name="encrypted">密文</param> /// <param name="key">密鑰</param> /// <param name="encoding">字符編碼方案</param> /// <returns>明文</returns> public static string Decrypt(string encrypted, string key, Encoding encoding) { byte[] buff = Convert.FromBase64String(encrypted); byte[] kb = System.Text.Encoding.Default.GetBytes(key); return encoding.GetString(Decrypt(buff, kb)); } /// <summary> /// 生成MD摘要 /// </summary> /// <param name="original">數(shù)據(jù)源</param> /// <returns>摘要</returns> private static byte[] MakeMD(byte[] original) { MD5CryptoServiceProvider hashmd = new MD5CryptoServiceProvider(); byte[] keyhash = hashmd.ComputeHash(original); hashmd = null; return keyhash; } /// <summary> /// 使用給定密鑰加密 /// </summary> /// <param name="original">明文</param> /// <param name="key">密鑰</param> /// <returns>密文</returns> private static byte[] Encrypt(byte[] original, byte[] key) { TripleDESCryptoServiceProvider des = new TripleDESCryptoServiceProvider(); des.Key = MakeMD(key); des.Mode = CipherMode.ECB; return des.CreateEncryptor().TransformFinalBlock(original, 0, original.Length); } /// <summary> /// 使用給定密鑰解密數(shù)據(jù) /// </summary> /// <param name="encrypted">密文</param> /// <param name="key">密鑰</param> /// <returns>明文</returns> private static byte[] Decrypt(byte[] encrypted, byte[] key) { TripleDESCryptoServiceProvider des = new TripleDESCryptoServiceProvider(); des.Key = MakeMD(key); des.Mode = CipherMode.ECB; return des.CreateDecryptor().TransformFinalBlock(encrypted, 0, encrypted.Length); } /// <summary> /// 使用給定密鑰加密 /// </summary> /// <param name="original">原始數(shù)據(jù)</param> /// <returns>密文</returns> private static byte[] Encrypt(byte[] original) { byte[] key = System.Text.Encoding.Default.GetBytes(DefaultKey); return Encrypt(original, key); } /// <summary> /// 使用缺省密鑰解密數(shù)據(jù) /// </summary> /// <param name="encrypted">密文</param> /// <returns>明文</returns> private static byte[] Decrypt(byte[] encrypted) { byte[] key = System.Text.Encoding.Default.GetBytes(DefaultKey); return Decrypt(encrypted, key); } public static string SimpEncrypt(string str) { StringBuilder asc = new StringBuilder(); for (int i = 0; i < str.Length; i++) { int b = char.Parse(str.Substring(i, 1)) + '\x0003'; asc.Append((char)b); } return asc.ToString(); } public static string SimpUnEncrypt(string str) { StringBuilder asc = new StringBuilder(); for (int i = 0; i < str.Length; i++) { int b = char.Parse(str.Substring(i, 1)) - '\x0003'; asc.Append((char)b); } return asc.ToString(); } }
2.配置文件相關(guān)操作 xml,ini配置文件的讀寫方法: using System; using System.Text; using System.Runtime.InteropServices; using System.Collections; using System.IO; using System.Collections.Generic; #region 配置文件讀寫操作類 /// <summary> /// 配置文件讀寫操作類 /// </summary> /// <date>2012-02-15</date> /// <author>xucj</author> public class IniFileHelper { #region 字段 private string path; #endregion #region 構(gòu)造函數(shù) public IniFileHelper(string iniFilePath) { path = iniFilePath; } #endregion #region 引用外部庫 [DllImport("kernel32")] private static extern long WritePrivateProfileString(string section, string key, string val, string filePath); [DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath); [DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string defVal, Byte[] retVal, int size, string filePath); #endregion #region 寫入INI文件 /// <summary> /// 寫入INI文件 /// </summary> /// <param name="section">段名</param> /// <param name="key">鍵名</param> /// <param name="value">鍵值</param> public void WriteValue(string section, string key, string value) { WritePrivateProfileString(section, key, value, this.path); } #endregion #region 刪除ini配置 /// <summary> /// 刪除ini文件下所有段落 /// </summary> public void ClearAllSection() { WriteValue(null, null, null); } /// <summary> /// 刪除ini文件下personal段落下的所有鍵 /// </summary> /// <param name="Section"></param> public void ClearSection(string Section) { WriteValue(Section, null, null); } #endregion #region 讀取INI文件 /// <summary> /// 讀取INI文件 /// </summary> /// <param name="section"></param> /// <param name="key"></param> /// <returns></returns> public string ReadValue(string section, string key) { StringBuilder temp = new StringBuilder(255); int i = GetPrivateProfileString(section, key, "", temp, 255, this.path); return temp.ToString(); } private byte[] ReadValues(string section, string key) { byte[] temp = new byte[255]; int i = GetPrivateProfileString(section, key, "", temp, 255, this.path); return temp; } /// <summary> /// 讀取ini文件的所有段落名 /// </summary> private string[] ReadValues() { byte[] allSection = ReadValues(null, null); return ByteToString(allSection); } /// <summary> /// 轉(zhuǎn)換byte[]類型為string[]數(shù)組類型 /// </summary> /// <param name="sectionByte"></param> /// <returns></returns> private string[] ByteToString(byte[] sectionByte) { ASCIIEncoding ascii = new ASCIIEncoding(); //編碼所有key的string類型 string sections = ascii.GetString(sectionByte); //獲取key的數(shù)組 string[] sectionList = sections.Split(new char[1] { '\0' }); return sectionList; } /// <summary> /// 讀取ini文件的某段落下所有鍵名 /// </summary> private string[] ReadValues(string section) { byte[] sectionByte = ReadValues(section, null); return ByteToString(sectionByte); } #endregion #region 不使用API方法 private Dictionary<string, string> configInfo = new Dictionary<string,string>(); //* 存放Ini文件配制信息 public int Count { get { return configInfo.Count; } } public string this[string key] { get { if (configInfo.ContainsKey(key)) { return configInfo[key].ToString(); } else { return "No this key-value"; } } } /// <summary> /// 讀取指定INI文件中的配置信息 /// </summary> /// <param name="file">配置文件的完整路徑名</param> /// <param name="section">配置文件中的節(jié)名 "[" + section + "]"形式</param> public IniFileHelper(string file, string section) { string Section = "[" + section + "]"; LoadIniFile(file, Section); } /// <summary> /// 讀取ini文件，以HashTable的格式存放 /// </summary> /// <param name="filePath">ini文件路徑</param> /// <param name="section">ini讀取的段名</param> private void LoadIniFile(string filePath, string section) { try { StreamReader sr = new StreamReader(filePath, System.Text.Encoding.Default); string readLine = null; bool IsReadEnd = false; string[] keys; while ((readLine = sr.ReadLine()) != null) { if (readLine == section) { while ((readLine = sr.ReadLine()) != null) { if(readLine != "") { if (readLine.Substring(0, 1) == "[") { IsReadEnd = true; break; } keys = readLine.Split('='); configInfo[keys[0].Trim()] = keys[1]; } } } if (IsReadEnd) { break; } } sr.Close(); } catch (Exception ex) { Console.WriteLine(ex.Message); configInfo.Clear(); } } #endregion } #endregion
這個主要是可序列化字典： /// <summary> /// 支持XML序列化的泛型Dictionary類 /// </summary> /// <typeparam name="TKey"></typeparam> /// <typeparam name="TValue"></typeparam> [XmlRoot("Dictionary")] [Serializable()] public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable { #region public SerializableDictionary() : base() { } public SerializableDictionary(IDictionary<TKey, TValue> dictionary) : base(dictionary) { } public SerializableDictionary(IEqualityComparer<TKey> comparer) : base(comparer) { } public SerializableDictionary(int capacity) : base(capacity) { } public SerializableDictionary(int capacity, IEqualityComparer<TKey> comparer) : base(capacity, comparer) { } protected SerializableDictionary(SerializationInfo info, StreamingContext context) : base(info, context) { } #endregion public XmlSchema GetSchema() { throw new NotImplementedException(); } /**/ /// <summary> /// 從對象的XML表示形式生成該對象 /// </summary> /// <param name="reader"></param> public void ReadXml(XmlReader reader) { XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); bool wasEmpty = reader.IsEmptyElement; reader.Read(); if (wasEmpty) return; while (reader.NodeType != XmlNodeType.EndElement) { reader.ReadStartElement("Key"); TKey key = (TKey)keySerializer.Deserialize(reader); reader.ReadEndElement(); reader.ReadStartElement("Value"); TValue value = (TValue)valueSerializer.Deserialize(reader); reader.ReadEndElement(); this.Add(key, value); reader.MoveToContent(); } reader.ReadEndElement(); } /// <summary> /// 將對象轉(zhuǎn)換為其XML表示形式 /// </summary> /// <param name="writer"></param> public void WriteXml(XmlWriter writer) { XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); foreach (TKey key in this.Keys) { writer.WriteStartElement("Key"); keySerializer.Serialize(writer, key); writer.WriteEndElement(); writer.WriteStartElement("Value"); TValue value = this[key]; valueSerializer.Serialize(writer, value); writer.WriteEndElement(); } } } 4.字符串 平時用的最多的肯定是字符串了,，所以肯定也少了它： using System; using System.Collections.Generic; using System.Text; public static class StringHelper { /// <summary> /// 將字符串轉(zhuǎn)換為base64編碼數(shù)據(jù) /// </summary> /// <param name="str"></param> /// <returns></returns> public static string ToBase64String(this string str) { byte[] data = System.Text.ASCIIEncoding.ASCII.GetBytes(str); return Convert.ToBase64String(data); } /// <summary> /// 將base64編碼數(shù)據(jù)轉(zhuǎn)換為字符串 /// </summary> /// <param name="str"></param> /// <returns></returns> public static string FromBase64String(this string str) { byte[] data = Convert.FromBase64String(str); return System.Text.ASCIIEncoding.ASCII.GetString(data); } } 5.漢轉(zhuǎn)英 在系統(tǒng)檢索菜品時,，要根據(jù)拼音，所以這個也不能少,，當(dāng)然這個也有其他的方法,，像存儲過程或依靠數(shù)據(jù)庫表都可以，下面是純C#代碼的： using System; using System.Collections.Generic; using System.Linq; using System.Text; public class GetPinYinHelper { /// <summary> /// 獲取拼音首字母 /// </summary> /// <param name="strCharacter">要轉(zhuǎn)換的中文漢字字符串</param> /// <returns>拼音縮寫</returns> /// <author>xucj</author> /// <date>2011-10-15</date> public static string GetInitialPinYin(string strCharacter) { string tempStr = string.Empty; foreach (char c in strCharacter) { if ((int)c >= 33 && (int)c <= 126 || (int)c == 32) { tempStr += c.ToString(); //字母和符號原樣保留,、同時空格也保留,。 } else { tempStr += GetPYChar(c.ToString()); //累加拼音聲母 } } return tempStr; } /// <summary> /// 取單個字符的拼音聲母 /// </summary> /// <param name="character">要轉(zhuǎn)換的單個漢字</param> /// <returns>拼音聲母</returns> /// <author>xucj</author> /// <date>2011-10-15</date> private static string GetPYChar(string character) { byte[] array = new byte[2]; array = System.Text.Encoding.Default.GetBytes(character); int i = (short)(array[0] - '\0') * 256 + ((short)(array[1] - '\0')); if (i < 0xB0A1) return "*"; if (i < 0xB0C5) return "a"; if (i < 0xB2C1) return "b"; if (i < 0xB4EE) return "c"; if (i < 0xB6EA) return "d"; if (i < 0xB7A2) return "e"; if (i < 0xB8C1) return "f"; if (i < 0xB9FE) return "g"; if (i < 0xBBF7) return "h"; if (i < 0xBFA6) return "j"; if (i < 0xC0AC) return "k"; if (i < 0xC2E8) return "l"; if (i < 0xC4C3) return "m"; if (i < 0xC5B6) return "n"; if (i < 0xC5BE) return "o"; if (i < 0xC6DA) return "p"; if (i < 0xC8BB) return "q"; if (i < 0xC8F6) return "r"; if (i < 0xCBFA) return "s"; if (i < 0xCDDA) return "t"; if (i < 0xCEF4) return "w"; if (i < 0xD1B9) return "x"; if (i < 0xD4D1) return "y"; if (i < 0xD7FA) return "z"; return "*"; } }  再加一個獲取本機的IP與機器名與MAC地址的方法： using System.Management; using System.Net; public class NetHelper { /// <summary> /// 取得本機IP /// </summary> public static string GetIP() { string hostName = Dns.GetHostName(); IPHostEntry ipEntry = Dns.GetHostEntry(hostName); IPAddress[] addr = ipEntry.AddressList; foreach (var item in addr) { if (item.AddressFamily == System.Net.Sockets.AddressFamily.InterNetworkV6) { continue; } return item.ToString(); } return null; } /// <summary> /// 獲取本機MAC地址 /// </summary> /// <returns></returns> public static string GetLocalMACAddress() { string mac = string.Empty; ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration"); ManagementObjectCollection queryCollection = query.Get(); foreach (ManagementObject mo in queryCollection) { if (mo["IPEnabled"].ToString() == "True") mac = mo["MacAddress"].ToString(); } return mac; } /// <summary> /// 獲取本機名 /// </summary> /// <returns></returns> public static string GetHostName() { string hostName = Dns.GetHostName(); return hostName; } } 當(dāng)然還有很多，等后面需要再慢慢加上來,，不相關(guān)的就不要了,，那樣肯定會太雜的，雖然有一些很好很優(yōu)雅的公共代碼,，但是如果系統(tǒng)用不上,，那也浪費了，那就讓它保存在備用庫里吧,。這些代碼來源還是廣泛的,，所以沒有太多好寫的，下次寫數(shù)據(jù)庫訪問模塊了,。主要實現(xiàn)ORM這個功能，因為通用數(shù)據(jù)庫訪問模塊網(wǎng)絡(luò)上也是很多的,，時間上應(yīng)該不會占用太多時間,，但是用ORM的話還是能夠減少寫SQL語句的時間，所以寫一個帶ORM功能的數(shù)據(jù)庫訪問模塊,。能不用寫SQL的地方就靠它了,。 當(dāng)然還有其他代碼，就不貼這里了,，有需要的就mark下,，沒人mark的話就...........
