C# ListView如何以编程方式创建ContextMenu

ContextMenu contextMenu = new ContextMenu();

MenuItem deleteMenuItem = new MenuItem("删除");
deleteMenuItem.Click += DeleteMenuItem_Click;

contextMenu.MenuItems.Add(deleteMenuItem);

listView1.ContextMenuStrip = contextMenu;

using System;
using System.Windows.Forms;

namespace ListViewContextMenuExample
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            
            // 创建ContextMenu对象
            ContextMenu contextMenu = new ContextMenu();

            // 创建MenuItem对象并设置文本和点击事件处理程序
            MenuItem deleteMenuItem = new MenuItem("删除");
            deleteMenuItem.Click += DeleteMenuItem_Click;

            // 将MenuItem添加到ContextMenu中
            contextMenu.MenuItems.Add(deleteMenuItem);

            // 将ContextMenu与ListView关联
            listView1.ContextMenuStrip = contextMenu;
        }

        private void DeleteMenuItem_Click(object sender, EventArgs e)
        {
            // 处理删除菜单项的点击事件
            if (listView1.SelectedItems.Count > 0)
            {
                foreach (ListViewItem item in listView1.SelectedItems)
                {
                    listView1.Items.Remove(item);
                }
            }
        }
    }
}
