请问一问题：怎么处理动态生成的菜单的不同事件？

//代码如下:

using System.Windows.Forms;
using System.Xml;
using System.Drawing;

//MessageBox.Show((aForm.GetType()).ToString());
}

int i = 0;
foreach ( XmlElement element in _oMainMenu )

}

//如何处理事件？请指教
MenuItemEX _oParentMenu = new MenuItemEX(menuName, new EventHandler( SelectMenuItem ) );
//MenuItem _oParentMenu = new MenuItem(menuName);

if ( menuChecked == "True" )
_oParentMenu.Checked = true;

{

string myclick = myHash[item.Text].ToString();

XML文件如下:

1<mainmenu>
2<menu checked="False" enabled="True" formname="form2" name="&amp;File" onclick="File_Click" openform="Form2" radio="False">
3<menu checked="False" enabled="False" formname="form2" name="&amp;New" onclick="Void newclick()" openform="Form2" radio="False"></menu>
4<menu checked="False" enabled="True" formname="form2" name="&amp;Open" onclick="Void openclick()" openform="Form2" radio="False"></menu>
5<menu checked="False" enabled="True" formname="form2" name="&amp;Close" onclick="Void closeclick()" openform="Form2" radio="False"></menu>
6</menu>
7</mainmenu>

上面是一个根据XML文件来动态生成菜单的例子，你自己修改一下。
