推荐答案

检查如何将ToolStripMenuItems添加到动态的MenuStrip或ContextMenu [ ^ ]

当您添加菜单项时，为它们提供唯一的文本，然后您可以轻松识别事件发送方对象单击的菜单项。 />
示例代码：

check How to add ToolStripMenuItems to a MenuStrip or ContextMenu dynamically[^]
When you add menu items give unique text for them, then you can easily identify which menu item clicked by event sender object.
Sample code:

ToolStripMenuItem menu = new ToolStripMenuItem(submenuName);
menu.Click += new EventHandler(menu_Click);
myToolStripMenuItem.DropDown.Items.Add(menu);
// add the event as below
void menu_Click(object sender, EventArgs e)
{
    var menuItem = sender as MenuItem; 
    var menuText = menuItem.Text;

    switch(menuText) {
        case "MenuItem1":
           // menu item1 clicked .. do something 
           break;

        case "MenuItem2":
          // menu item2 clicked .. do something 
          break;
         . ...
}

使用Name propeerty而不是Text属性

Use the Name propeerty instead of the Text property
