var filePicker = new FileOpenPicker();
filePicker.FileTypeFilter.Add(".jpg");
var result = await filePicker.PickSingleFileAsync();
if (result != null)
{
using (IRandomAccessStream stream = await result.OpenAsync(FileAccessMode.Read))
{
BitmapDecoder decoder = await BitmapDecoder.CreateAsync(stream);
WriteableBitmap bmp = new WriteableBitmap((int)decoder.PixelWidth, (int)decoder.PixelHeight);
bmp.SetSource(stream);
// show the image in the UI if you want.
MyImage.Source = bmp;
}
}
这样你可以使用WriteableBitmap，你可以使用WriteableBitmapEx库。
