C#列表框拖放行

我试图用一个列表框实现一个C#拖放行重新排序。我在网上遇到过一些代码片段，但似乎没有一个能满足我的需要

---

我希望您向我展示一个如何在ListBox中移动行的示例代码

---

谢谢

行的移动在方法“listBox1_MouseUp和listBox1_MouseDown”中完成

使用视图代码更改此设置：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Calculator
{
    public partial class ComponentMover : Form
    {
        private Control trackedControl;
        private int gridWidth = 100, gridHeight = 20;
        private int row;

        public ComponentMover()
        {
            this.InitializeComponent();
            this.InitializeDynamic();
        }

        void draggable_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
        {
            if (this.trackedControl == null)
                this.trackedControl = (Control)sender;
        }

        void draggable_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
        {
            if (this.trackedControl != null)
            {
                int x = e.X + this.trackedControl.Location.X;
                int y = e.Y + this.trackedControl.Location.Y;
                Point moved = new Point(x - x % this.gridWidth, y - y % this.gridHeight);

                Console.WriteLine(e.X + ", " + e.Y + ", " + ", " + moved.X + ", " + moved.Y);
                if (moved != this.trackedControl.Location)
                    this.trackedControl.Location = moved;
            }
        }

        void draggable_MouseUp(object sender, MouseEventArgs e)
        {
            this.trackedControl = null;
        }

        private void AddDragListeners(Control draggable)
        {
            draggable.MouseDown += new MouseEventHandler(draggable_MouseDown);
            draggable.MouseMove += new MouseEventHandler(draggable_MouseMove);
            draggable.MouseUp += new MouseEventHandler(draggable_MouseUp);
        }
    }
}
