解决办法是在控件初始化时,通过下面方法再次加载图片:
ucCanvas.CreateCoordinateImage.Source = GetImageIcon(global::MainApplication.Properties.Resources.DL_Coordinate2);
private static BitmapImage GetImageIcon(System.Drawing.Bitmap bitmap)
{
BitmapImage bitmapImage = new BitmapImage(); try
{ System.IO.MemoryStream ms = new System.IO.MemoryStream();
bitmap.Save(ms, bitmap.RawFormat);
bitmapImage.BeginInit();
bitmapImage.StreamSource = ms;
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.EndInit();
bitmapImage.Freeze(); }
catch (Exception ex)
{ Utilities.ShowExceptionMessage(ex);
} return bitmapImage;
}
