C#備份和恢復(fù)SQL Server數(shù)據(jù)庫

 昵稱10504424 2013-02-18
SQLDMO(SQL Distributed Management Objects,,SQL分布式管理對(duì)象)封裝了Microsoft SQL Server數(shù)據(jù)庫中的對(duì)象。SQLDMO是Microsoft SQL Server中企業(yè)管理器所使用的應(yīng)用程序接口,,所以它可以執(zhí)行很多功能,,其中當(dāng)然也包括對(duì)數(shù)據(jù)庫的備份和恢復(fù),。

SQLDMO由Microsoft SQL Server自帶的SQLDMO.dll提供,,由于SQLDMO.dll是一個(gè)COM對(duì)象,,所以大家在用之前必須在.Net項(xiàng)目中添加對(duì)它的引用。
下面是用C#語言書寫的用于Microsoft SQL Server數(shù)據(jù)庫備份和恢復(fù)的類:

public sealed class DbOper
{
     ///<summary>
     /// DbOper類的構(gòu)造函數(shù)
///作者:Shadow
     ///</summary>
     private DbOper()
     {
     }

     ///<summary>
     /// 數(shù)據(jù)庫備份
     ///</summary>
     public static void DbBackup()
     {
          SQLDMO.Backup oBackup = new SQLDMO.BackupClass();
          SQLDMO.SQLServer oSQLServer = new SQLDMO.SQLServerClass();
         try
         {
              oSQLServer.LoginSecure = false;
              oSQLServer.Connect("localhost", "sa", "1234");
              oBackup.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database;
              oBackup.Database = "Northwind";
              oBackup.Files = @"d:/Northwind.bak";
              oBackup.BackupSetName = "Northwind";
              oBackup.BackupSetDescription = "數(shù)據(jù)庫備份";
              oBackup.Initialize = true;
              oBackup.SQLBackup(oSQLServer);
         }
         catch
         {
              throw;
         }
          finally
         {
              oSQLServer.DisConnect();
         }
     }

     ///<summary>
     /// 數(shù)據(jù)庫恢復(fù)
     ///</summary>
     public static void DbRestore()
     {
          SQLDMO.Restore oRestore = new SQLDMO.RestoreClass();
          SQLDMO.SQLServer oSQLServer = new SQLDMO.SQLServerClass();
         try
         {
              oSQLServer.LoginSecure = false;
              oSQLServer.Connect("localhost", "sa", "1234");
              oRestore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database;
              oRestore.Database = "Northwind";
              oRestore.Files = @"d:/Northwind.bak";
              oRestore.FileNumber = 1;
              oRestore.ReplaceDatabase = true;
              oRestore.SQLRestore(oSQLServer);
         }
         catch
         {
              throw;
         }
          finally
         {
              oSQLServer.DisConnect();
         }
     }
}
