测试打印功能

// 先创建窗体，后拉入Button控件两个，一个预览功能，一个打印功能，再拉入控件PrintDocument控件、PrintPreviewDilogs控件、pageSetupDilogs控件

// 后台代码

 1 List<string> students = new List<string>() {"张三","李四","王五" };
 2         int count = 0;//要打印的学员姓名的下标值

 8             //g.DrawLine(new Pen(Color.Red),new Point(200,200),new Point(300,200));
 9             g.Dispose();
10             count++;//递增，为了打印下一个姓名
11             //判断打印是否结束
