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; }
