Answer 1

            System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
            System.Drawing.Printing.PrintDocument docToPrint = new System.Drawing.Printing.PrintDocument();
            docToPrint.PrintPage +=new System.Drawing.Printing.PrintPageEventHandler(docToPrint_PrintPage);
            PrintDialog1.AllowSomePages = true; 
            PrintDialog1.ShowHelp = true;
            
            PrintDialog1.Document = docToPrint;            DialogResult result = PrintDialog1.ShowDialog();            if (result == DialogResult.OK)
            {
                docToPrint.Print();
            }网上找的代码,但不太明白怎么用,docToPrint_PrintPage事件也不知道该写点什么
