C#中的PrintDialog组件的应用实例
PrintDialog组件的应用
下面通过一个例子来说明PrintDialog组件的用法。
程序开发步骤如下所示。
（1）打开上一节的项目，继续在Windows窗体上添加一个PrintDialog组件。
（2）双击窗体中的按钮，在双击事件中添加如下代码：
private void button1_Click(object sender, EventArgs e)
{
pageSetupDialog1.Document = printDocument1;
pageSetupDialog1.ShowDialog();
printDialog1.Document = printDocument1;
printDialog1.ShowDialog();
}
程序运行结果如图1所示。
完整程序代码如下：
