        ToolStripMenuItem AddContextMenu(stringtext, ToolStripItemCollection cms, EventHandler callback)
        {
            if(text == "-")

                tsmi.Tag = text +"TAG";
                if(callback != null) tsmi.Click += callback;
                cms.Add(tsmi);
  
                returntsmi;
            }
  
            returnnull;
        }
  
        voidMenuClicked(objectsender, EventArgs e)
        {
     //以下主要是动态生成事件并打开窗体
  
    //((sender as ToolStripMenuItem).Tag)强制转换
  
            ObjectHandle t = Activator.CreateInstance("WinForms","WinForms.Form2");
            Form f = (Form)t.Unwrap();
            f.ShowDialog();
  
        }
