关闭窗口时出现确认框架

 1 protected override void Dispose( bool disposing )
 2         {
 3             if(MessageBox.Show(this,"您真的要退出吗?","退出询问",MessageBoxButtons.YesNo,MessageBoxIcon.Question)==DialogResult.Yes )
 4             {
 5                 if( disposing )
 6                 {
 7                     if(components != null)
 8                     {
 9                         components.Dispose();
10                     }
11                 }
12                 base.Dispose( disposing );
13             }
14         }

   很简单.但是平时常常用到.各位同僚如果认为不妥之处,还望多多指教!
