WPF的Image控件的资源切换

首先需要做一个资源类，把图片资源放到这个类里。

然后需要一个转换Converter类。

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
		{

			System.Drawing.Bitmap bitmap = (System.Drawing.Bitmap)value;
			
			if (bitmap != null)
			{
				System.Windows.Media.ImageSource source = Imaging.CreateBitmapSourceFromHBitmap(bitmap.GetHbitmap(),
					IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
				return source;
			}
			else
				return null;
		}

		public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
		{
			throw new NotImplementedException();
		}

最后就是在xaml里用了。

<Image Width="300" Height="80" Source="{Binding NameBitmap,Converter={StaticResource ImageConverter}}"  RenderOptions.BitmapScalingMode="Fant"></Image>
