我导入数据后，picturebox内自动生成了曲线图，我另加了一个打印按钮，希望按下打印按钮后，能够打印picturebox内的曲线图，我是一个初学者，希望高手帮帮忙，先谢谢了！

不懂，只听说C#有打印文档的控件！

        /// <summary>
        /// 打印
        /// </summary>
        /// <param name="title">标题</param>
        /// <param name="printPageEventHandler"></param>
        public static void Print(string title, PrintPageEventHandler printPageEventHandler)
        {
            PrintDocument printDocument1 = new PrintDocument();
            PageSetupDialog pageSetupDialog1 = new PageSetupDialog();
            PrintPreviewDialog printPreviewDialog1 = new PrintPreviewDialog();
            PrintDialog printDialog1 = new PrintDialog();

            printDocument1.PrintPage += printPageEventHandler;
            printDocument1.DocumentName = title;
            pageSetupDialog1.PageSettings = new PageSettings();
           
            if (pageSetupDialog1.ShowDialog() == DialogResult.OK)
            {
                printDocument1.DefaultPageSettings = pageSetupDialog1.PageSettings;
                //打印前设置打印机
                printDialog1.PrinterSettings = new PrinterSettings();
                printDialog1.Document = printDocument1;
                printPreviewDialog1.Document = printDocument1;
                // 预览
                printPreviewDialog1.ShowDialog();
               
                if (printDialog1.ShowDialog() == DialogResult.OK)
                {
                    printDocument1.Print();
                }
            }
        }

// 调用
Print("打印曲线图", (sender, e) => { e.Graphics.DrawImage(pictureBox1.Image, 0, 0); });

高手

我不明白打印事件是怎么发生的
如果我是：
 private void button2_Click(object sender, EventArgs e)
{
            PrintDialog MyPrintDg = new PrintDialog();
            MyPrintDg.Document = printDocument2;
            printDocument2.PrintPage += new PrintPageEventHandler(this.printDocument2_PrintPage);
            if (MyPrintDg.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    printDocument2.Print();
                }
                catch
                {   //停止打印
                    printDocument2.PrintController.OnEndPrint(printDocument2, new System.Drawing.Printing.PrintEventArgs());
                }
            }
        }
 private void printDocument2_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            e.Graphics.DrawImage(pictureBoxBoXing.Image, 0, 0);
            e.HasMorePages = true;//允许多页打印
         }
这是哪儿错了，根本打印不出东西来，特别是到e.Graphics.DrawImage(pictureBoxBoXing.Image, 0, 0);
这一句就不执行了！希望你指点一下，谢谢了！

程序应该没问题，检查一下打印机设置好了没。
我没连打印机真正打印过，只是弹出那些打印设置界面，然后点打印就卡在那“正在打印”。
呵呵。。。
