推荐答案

Hello Ravindra，

要从PhotoChooserTask将图像保存到IsolatedStorage，请使用此（任务回调中的e对象保存流。

Hello Ravindra,
To save an image to IsolatedStorage from a PhotoChooserTask, use this (the e object in the task callback holds the stream.

public static void SaveImage(Stream imageStream, string fileName, int orientation, int quality)
{
    using (var isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
    {
        if (isolatedStorage.FileExists(fileName))
            isolatedStorage.DeleteFile(fileName);

        IsolatedStorageFileStream fileStream = isolatedStorage.CreateFile(fileName);
        BitmapImage bitmap = new BitmapImage();
        bitmap.SetSource(imageStream);

        WriteableBitmap wb = new WriteableBitmap(bitmap);
        wb.SaveJpeg(fileStream, wb.PixelWidth, wb.PixelHeight, orientation, quality);
        fileStream.Close();
    }
}
