克隆和修改鼠标/手写笔事件而不在C#中劫持光标？

using System;
using System.Windows.Forms;

public class MyForm : Form
{
    public MyForm()
    {
        MouseDown += new MouseEventHandler(Form_MouseDown);
        MouseMove += new MouseEventHandler(Form_MouseMove);
        MouseUp += new MouseEventHandler(Form_MouseUp);
    }

    private void Form_MouseDown(object sender, MouseEventArgs e)
    {
        // 克隆鼠标事件参数
        MouseEventArgs clonedArgs = (MouseEventArgs)e.Clone();

        // 修改鼠标事件参数
        clonedArgs.Location = new Point(e.X + 10, e.Y + 10);
        clonedArgs.Button = MouseButtons.Left;

        // 处理修改后的鼠标事件
        base.OnMouseDown(clonedArgs);
    }

    private void Form_MouseMove(object sender, MouseEventArgs e)
    {
        // 克隆鼠标事件参数
        MouseEventArgs clonedArgs = (MouseEventArgs)e.Clone();

        // 修改鼠标事件参数
        clonedArgs.Location = new Point(e.X + 10, e.Y + 10);
        clonedArgs.Button = MouseButtons.Left;

        // 处理修改后的鼠标事件
        base.OnMouseMove(clonedArgs);
    }

    private void Form_MouseUp(object sender, MouseEventArgs e)
    {
        // 克隆鼠标事件参数
        MouseEventArgs clonedArgs = (MouseEventArgs)e.Clone();

        // 修改鼠标事件参数
        clonedArgs.Location = new Point(e.X + 10, e.Y + 10);
        clonedArgs.Button = MouseButtons.Left;

        // 处理修改后的鼠标事件
        base.OnMouseUp(clonedArgs);
    }
