  var topLeft = control.PointToScreen(new Point(0, 0));
            var bitmap = ScreenCapture.Capture(
                (int)topLeft.X,
                (int)topLeft.Y,
                (int)control.ActualWidth,
                (int)control.ActualHeight);
            bitmap.Save(path);

 

设置图形大小，然后保存为path路径图片。
