方法一：
本地圖片庫(kù)選擇圖片進(jìn)行顯示：
async
private void LoadPictureByPicker()
{
FileOpenPicker
fileOpen =
new FileOpenPicker()
{
FileTypeFilter={
".jpg",
".jpeg",
".png",
".bmp" },
ViewMode=PickerViewMode.Thumbnail,
SuggestedStartLocation=PickerLocationId.PicturesLibrary
};
bitmapImage
=
new BitmapImage();
storageFile
= await fileOpen.PickSingleFileAsync();
if (storageFile
!=
null)
{
using (IRandomAccessStream
stream = await
storageFile.OpenAsync(FileAccessMode.Read))
{
bitmapImage.SetSource(stream);
}
}
this.image.Source
= bitmapImage;
}
方法二：
請(qǐng)求網(wǎng)絡(luò)URL：
async
private void LoadPictrueByUrl()
{
var
rass =
RandomAccessStreamReference.CreateFromUri(new Uri(url));
var streamRandom
= await rass.OpenReadAsync();
BitmapImage
bitmapImage =
new BitmapImage();
bitmapImage.SetSource(streamRandom);
this.image.Source
= bitmapImage;
}
方法三：
顯示項(xiàng)目文件圖片：
string url = "ms-appx:///Images/flower.jpg";
async
private void LoadPictureByNative()
{
var
rass =
RandomAccessStreamReference.CreateFromUri(new Uri(url));
streamRandom
= await rass.OpenReadAsync();
var
bitmapImage =
new BitmapImage();
bitmapImage.SetSource(streamRandom);
img.Source
= bitmapImage;
}
