介绍几种常用的Image source 赋值方式：

this.abc.Source = new BitmapImage(new Uri("/1.jpg", UriKind.RelativeOrAbsolute));

Uri uri = new Uri("1.jpg", UriKind.Relative);ImageSource imgSource = new System.Windows.Media.Imaging.BitmapImage(uri);   this.abc.SetValue(Image.SourceProperty, imgSource);

this.abc.Source = new BitmapImage(new Uri("F:\\1.jpg", UriKind.RelativeOrAbsolute));

/{程序集名};component搜索/{图片资源路径}

var uri = new Uri("/AppleMenu;component/Res/" + value + ".png", UriKind.Relative);                IconImage.Source = new System.Windows.Media.Imaging.BitmapImage(uri);
