用法示例:

private void GetPoc1 (MouseButtons mb) { // 回调处理 if (mb == MouseButtons.Left) {  MessageBox.Show ("来自菜单1"); }}privateShell_NotifyIconEx o1 = newShell_NotifyIconEx (); //这个放外面是用在 o.DelNotifyBoxprivate void button1_Click (object sender, System.EventArgs e) { o1.AddNotifyBox (this.Icon.Handle, this.Text, "菜单1", "单击这里开始，我将带你畅游API 世界"); o1.ConnectMyMenu (this.Handle, this.contextMenu1.Handle); // 挂上菜单，可选 o1._delegateOfCallBack = newShell_NotifyIconEx.delegateOfCallBack (GetPoc1); //定义回调}
