C#之鼠标模拟技术

游戏程序的操作不外乎两种——键盘输入控制和鼠标输入控制,几乎所有游戏中都使用鼠标来改变角色的位置和方向,本文主要是讲述如何使用C#调用Windows API函数实现鼠标模拟操作的功能.首先通过结合FindWindow和FindWindowEx寻找到窗体的按钮,在通过SetCursorPos或mouse_event函数操作鼠标,同时涉及到通过spy++工具获取窗体消息的信息.

鼠标自动点击按钮和查看鼠标运行轨迹:

首先创建一个C#工程,设计的窗体如下图所示,同时添加Timer时间器控件:

然后添加的如下代码,即可实现鼠标模拟技术及自动操作鼠标:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

//引用新命名空间

using System.Runtime.InteropServices;  //StructLayout

 

namespace MouseAction

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

 

        //结构体布局 本机位置

        [StructLayout(LayoutKind.Sequential)]

        struct NativeRECT

        {

            public int left;

            public int top;

            public int right;

            public int bottom;

        }

 

        //将枚举作为位域处理

        [Flags]

        enum MouseEventFlag : uint //设置鼠标动作的键值

        {

            Move = 0x0001,               //发生移动

            LeftDown = 0x0002,           //鼠标按下左键

            LeftUp = 0x0004,             //鼠标松开左键

            RightDown = 0x0008,          //鼠标按下右键

            RightUp = 0x0010,            //鼠标松开右键

            MiddleDown = 0x0020,         //鼠标按下中键

            MiddleUp = 0x0040,           //鼠标松开中键

            XDown = 0x0080,

            XUp = 0x0100,

            Wheel = 0x0800,              //鼠标轮被移动

            VirtualDesk = 0x4000,        //虚拟桌面

            Absolute = 0x8000

        }

 

        //设置鼠标位置

        [DllImport("user32.dll")]

        static extern bool SetCursorPos(int X, int Y);

 

        //设置鼠标按键和动作

        [DllImport("user32.dll")]

        static extern void mouse_event(MouseEventFlag flags, int dx, int dy,

            uint data, UIntPtr extraInfo); //UIntPtr指针多句柄类型

 

        [DllImport("user32.dll")]

        static extern IntPtr FindWindow(string strClass, string strWindow);

 

        //该函数获取一个窗口句柄,该窗口雷鸣和窗口名与给定字符串匹配 hwnParent=Null从桌面窗口查找

        [DllImport("user32.dll")]

        static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter,

            string strClass, string strWindow);

        

        [DllImport("user32.dll")]

        static extern bool GetWindowRect(HandleRef hwnd, out NativeRECT rect);

 

        //定义变量

        const int AnimationCount = 80;        

        private Point endPosition;           

        private int count;

 

        private void button1_Click(object sender, EventArgs e)

        {

            NativeRECT rect;

            //获取主窗体句柄

            IntPtr ptrTaskbar = FindWindow("WindowsForms10.Window.8.app.0.2bf8098_r11_ad1", null);

            if (ptrTaskbar == IntPtr.Zero)

            {

                MessageBox.Show("No windows found!");

                return;

            }

            //获取窗体中"button1"按钮

            IntPtr ptrStartBtn = FindWindowEx(ptrTaskbar, IntPtr.Zero, null, "button1");

            if (ptrStartBtn == IntPtr.Zero)

            {

                MessageBox.Show("No button found!");

                return;

            }

            //获取窗体大小

            GetWindowRect(new HandleRef(this, ptrStartBtn), out rect);

            endPosition.X = (rect.left + rect.right) / 2;

            endPosition.Y = (rect.top + rect.bottom) / 2;

            //判断点击按钮

            if (checkBox1.Checked)

            {

                //选择"查看鼠标运行的轨迹"

                this.count = AnimationCount;

                movementTimer.Start();

            }

            else

            {

                SetCursorPos(endPosition.X, endPosition.Y);

                mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);

                mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);

                textBox1.Text = String.Format("{0},{1}", MousePosition.X, MousePosition.Y);

            }

 

        }

 

        //Tick:定时器,每当经过多少时间发生函数

        private void movementTimer_Tick(object sender, EventArgs e)

        {

            int stepx = (endPosition.X - MousePosition.X) / count;

            int stepy = (endPosition.Y - MousePosition.Y) / count;

            count--;

            if (count == 0)

            {

                movementTimer.Stop();

                mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);

                mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);

            }

            textBox1.Text = String.Format("{0},{1}", MousePosition.X, MousePosition.Y);

            mouse_event(MouseEventFlag.Move, stepx, stepy, 0, UIntPtr.Zero);

        }

    }

}

 

同时自定义一个对话框,增加一个button按钮,其运行结果如下图所示:
