You can just use these two methods:

 public static BitmapSource ConvertBitmap(Bitmap source)  {   return System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(   source.GetHbitmap(),   IntPtr.Zero,   Int32Rect.Empty,   BitmapSizeOptions.FromEmptyOptions());  }  public static Bitmap BitmapFromSource(BitmapSource bitmapsource)  {   Bitmap bitmap;   using (var outStream = new MemoryStream())   {   BitmapEncoder enc = new BmpBitmapEncoder();   enc.Frames.Add(BitmapFrame.Create(bitmapsource));   enc.Save(outStream);   bitmap = new Bitmap(outStream);   }   return bitmap;  } 

It works perfectly for me
