问题 I am trying set the source of an Image in code with a BitmapImage but nothing shows up here is my code: xaml: <Image x:Name="img" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Fill" /> Code behind: var image = new BitmapImage(new Uri(@"C:\Users\XXX\Pictures\image.jpg", UriKind.Absolute)); image.DecodePixelWidth = 100; this.img.Source = image; 回答1: It's a permissions issue.
