c# 如何 实现 鼠标控制?

Question

我想通过 windows服务 实现...
比如 服务打开的 时候 
判断程序 程序没打开 就控制 鼠标不能动...
然后 服务打开程序后 鼠标才能动...我只知道 窗体 的 鼠标 控制...没打开窗体 怎么控制...谢谢先!

Answer 1

那和.NET平台好像没有关联哦
在Windows上操作鼠标？

Answer 2

肯定要用上API了`~  服务启动的时候鼠标就能运行`没有启动就不能运行` 

Answer 3

就是几个API，很简单的。看看就懂了。
using System;
using System.Threading;
using System.Runtime.InteropServices;
using System.Windows.Forms;namespace MouseControl
{
    class MouseControl
    {
        /// <summary>
        /// 鼠标控制参数
        /// </summary>
        const int MOUSEEVENTF_LEFTDOWN = 0x2;
        const int MOUSEEVENTF_LEFTUP = 0x4;
        const int MOUSEEVENTF_MIDDLEDOWN = 0x20;
        const int MOUSEEVENTF_MIDDLEUP = 0x40;
        const int MOUSEEVENTF_MOVE = 0x1;
        const int MOUSEEVENTF_ABSOLUTE = 0x8000;
        const int MOUSEEVENTF_RIGHTDOWN = 0x8;
        const int MOUSEEVENTF_RIGHTUP = 0x10;
        
        /// <summary>
        /// 鼠标的位置
        /// </summary>
        public struct PONITAPI
        {
            public int x, y;
        }        [DllImport("user32.dll")]
        public static extern int GetCursorPos(ref PONITAPI p);        [DllImport("user32.dll")]
        public static extern int SetCursorPos(int x, int y);        [DllImport("user32.dll")]
        public static extern int mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);        [STAThread]
        static void Main()
        {
            PONITAPI p = new PONITAPI();
            GetCursorPos(ref p);
            Console.WriteLine("鼠标现在的位置X:{0}, Y:{1}", p.x, p.y);
            Console.WriteLine("Sleep 1 sec...");
            Thread.Sleep(1000);            p.x = (new Random()).Next(Screen.PrimaryScreen.Bounds.Width);
            p.y = (new Random()).Next(Screen.PrimaryScreen.Bounds.Height);
            Console.WriteLine("把鼠标移动到X:{0}, Y:{1}", p.x, p.y);
            SetCursorPos(p.x, p.y);
            GetCursorPos(ref p);
            Console.WriteLine("鼠标现在的位置X:{0}, Y:{1}", p.x, p.y);
            Console.WriteLine("Sleep 1 sec...");
            Thread.Sleep(1000);            Console.WriteLine("在X:{0}, Y:{1} 按下鼠标左键", p.x, p.y);
            mouse_event(MOUSEEVENTF_LEFTDOWN, p.x, p.y, 0, 0);
            Console.WriteLine("Sleep 1 sec...");
            Thread.Sleep(1000);            Console.WriteLine("在X:{0}, Y:{1} 释放鼠标左键", p.x, p.y);
            mouse_event(MOUSEEVENTF_LEFTUP, p.x, p.y, 0, 0);
            Console.WriteLine("程序结束，按任意键退出....");
            Console.ReadKey();
        }
    }
