打印问题

Question

 private void print(object sender, EventArgs e)
        {
            printDialog1.Document = printDocument1;
            StringReader MySReader = new StringReader(richTextBox1.Text);
            if(printDialog1.ShowDialog()==DialogResult.OK)
            {
                try
                {
                    printDocument1.Print();
                }
                catch
                {
                    printDocument1.PrintController.OnEndPrint(printDocument1, new System.Drawing.Printing.PrintEventArgs());
                }
            }
为什么我打印不出TEXT的！什么问题，总感觉stringreader对象用不上！print方法又没参数重载！求解

Answer 1

追加个问题就是printDialog1.Document = printDocument1;这句什么意思啊，=printDocument有什么用呢

Answer 2

printDocument1_PrintPage事件中用
e.Graphics.DrawString（）绘制页面才能打印
