东西不难。

使用的函数那么几个。

本例是我删除淘宝购物记录时写的，所以是两个坐标点来回移动并点击鼠标左键。

using System;
using System.Runtime.InteropServices;
using System.Threading;

namespace 鼠标移动且点击
{
    public enum MouseType
    {
        //移动鼠标 
        MOUSEEVENTF_MOVE = 0x0001,
        //模拟鼠标左键按下 
        MOUSEEVENTF_LEFTDOWN = 0x0002,
        //模拟鼠标左键抬起 
        MOUSEEVENTF_LEFTUP = 0x0004,
        //模拟鼠标右键按下 
        MOUSEEVENTF_RIGHTDOWN = 0x0008,
        //模拟鼠标右键抬起 
        MOUSEEVENTF_RIGHTUP = 0x0010,
        //模拟鼠标中键按下 
        MOUSEEVENTF_MIDDLEDOWN = 0x0020,
        //模拟鼠标中键抬起 
        MOUSEEVENTF_MIDDLEUP = 0x0040,
        //标示是否采用绝对坐标 
        MOUSEEVENTF_ABSOLUTE = 0x8000,
