如何把panel保存成图片？

[seraphgxh]

我在panel中方了一些控件，我如何才能做到把整个panel（包括里面的控件）保存成一个图片？

[lovefootball]

Graphics g1 = panel1.CreateGraphics();
Image myImage = new Bitmap(this.panel1.Width, this.panel1.Height, g1);
Graphics g2 = Graphics.FromImage(myImage);
IntPtr dc1 = g1.GetHdc();
IntPtr dc2 = g2.GetHdc();
BitBlt(dc2, 0, 0, this.panel1.Width, this.panel1.Height, dc1, 0, 0, 13369376);
g1.ReleaseHdc(dc1);
g2.ReleaseHdc(dc2);
myImage.Save(@"e:\1.bmp", ImageFormat.Bmp);

[System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")]
private static extern bool BitBlt(
IntPtr hdcDest, // handle to destination DC
int nXDest, // x-coord of destination upper-left corner
int nYDest, // y-coord of destination upper-left corner
int nWidth, // width of destination rectangle
int nHeight, // height of destination rectangle
IntPtr hdcSrc, // handle to source DC
int nXSrc, // x-coordinate of source upper-left corner
int nYSrc, // y-coordinate of source upper-left corner
System.Int32 dwRop // raster operation code
);
