如何在C#中清除Cursor.Clip并允许光标再次自由移动？

using System;
using System.Windows.Forms;

namespace CursorClipExample
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // 清除 Cursor.Clip 以允许光标自由移动
            Cursor.Clip = Rectangle.Empty;
        }
    }
}
