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:
