ContextMenuStrip弹窗和传值问题

 1 //定义全局事件 send 和全局弹窗 CTMS
 2 public delegate void sendStr( string data );//委托类型声明
 3 public event sendStr send;//事件声明
 4 ContextMenuStrip CTMS = new ContextMenuStrip();//申明弹窗
 5 
 6 //CTMS 点击方法激活定阅
 7  private void CTMS_Click(object sender,EventArgs e)
 8 {
 9     ...
10     this.send += sendDelegateHandler;//订阅send事件
11     ...
12 }
13 
14 //send事件订阅方法
15 private void sendDelegateHandler( string T )
16 {
17     foreach ( var item in CTMS.Items )//遍历弹窗中每项
18     {
19         if ( item is ToolStripMenuItem )//有非ToolStripMenuItem，必须排除，否则有异常
20         {
21             ToolStripMenuItem ti = item as ToolStripMenuItem;//重新封装
22             if ( ti.Checked )//找到打勾的项
23             {
24                 ti.Text = T;//赋值为事件传出来的值
25             }
26         }
27     }
28 }
