我现在想实现的功能是当form2窗体打开后，不需要提示，直接就打印form2窗体中的全部内容，不知道有什么控件没有，直接添加就可以完成此功能。3我现在是在load事件中写this.PrintForm();但是不对，c#中可以这样写吗？？如果不能这么写，该怎么修改下，谢谢！！！！！！！
Bitmap memoryImage = null; //å®ä¹ä¸ä¸ªå¾ç
public static PrintDocument printDocument = new PrintDocument(); //å®ä¹ä¸ä¸ªPrintæ档对象
private void CaptureScreen()//æªå±
{
Form form = this;
if (form != null)
{
Graphics mygraphics = form.CreateGraphics();
memoryImage = new Bitmap(form.Width, form.Height, mygraphics);
Graphics memoryGraphics = Graphics.FromImage(memoryImage);
memoryGraphics.CopyFromScreen(form.Location.X, form.Location.Y, 0, 0, form.Size);
}
}

请使用PrintForm类，它可以直接打印窗体，具体用法请参看msdn
