# \---------事件 #

# \-------说明 #

通常情况下，创建 PrintDocument 类的一个实例，设置属性，如 DocumentNameand PrinterSettings，并调用 Print 方法开始执行打印进程。处理 PrintPage 事件，在其中指定要打印，使用 PrintPageEventArgs 的 GraphicsGraphics 属性的输出。

\---------代码事例

下下面的代码演示了打印指定文件的内容。

 ///---这里选择了打印按钮，那么执行打印
 printDocument1.Print();
 }
 }
 catch (Exception ex)
 {
 streamToPrint.Dispose();
 MessageBox.Show(ex.Message);
 }
 }
 #endregion 打印按钮被单击事件
 
 #region 打印事件被触发后，执行打印
 private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)

 ///---打印每一行

 }

 }
 else
 {

 }
 }
 catch (Exception ex)
 {
 MessageBox.Show(ex.Message);
 }
 }
 #endregion 打印事件被触发后，执行打印
 }
 }
