如何响应 ContextMenuStrip 项目单击

Question

目前我有以下代码：

ContextMenuStrip contexMenuuu = new ContextMenuStrip();

contexMenuuu.Items.Add("Edit ");
contexMenuuu.Items.Add("Delete " );
contexMenuuu.Show();

如何添加单击项目时要处理的事件？

Answer 1

这可以使用以下代码来完成：

ContextMenuStrip contexMenu = new ContextMenuStrip();

contexMenu.Items.Add("Edit ");
contexMenu.Items.Add("Delete ");
contexMenu.Show();
contexMenu.ItemClicked += new ToolStripItemClickedEventHandler(
    contexMenu_ItemClicked);

// ...

void contexMenu_ItemClicked(object sender, ToolStripItemClickedEventArgs e) {
    ToolStripItem item = e.ClickedItem;
    // your code here
}

或者：

// ...

ToolStripItem item = contexMenu.Items.Add("Edit ");
item.Click += new EventHandler(item_Click);

// ...

void item_Click(object sender, EventArgs e) {
    ToolStripItem clickedItem = sender as ToolStripItem;
    // your code here
}

Answer 2

Add 方法返回 ToolStripItem。所以你可以添加句柄到Click事件

        var item = contexMenuuu.Items.Add("Edit ");
        item.Click += methodToBeInvoked;
