二、KeyBoard
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace MouseMonitorW  
{  
    class KeyBoard  
    {  
        \[DllImport("user32.dll")\]  
        static extern void keybd\_event(byte bVk, byte bScan, uint dwFlags, int dwExtraInfo);  
        \[DllImport("user32.dll")\]  
        public static extern Keys VkKeyScan(char ch); 

        public static void sendKey(char key)  
        {  
            keybd\_event((byte)VkKeyScan(key), , , );  
            keybd\_event((byte)VkKeyScan(key), , , );  
        }  
    }  
}

三、Mouse：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;

namespace MouseMonitorW  
{  
    class Mouse  
    {  
        private const int MOUSEEVENTF\_MOVE          = 0x0001;   // 移动鼠标  
        private const int MOUSEEVENTF\_LEFTDOWN      = 0x0002;   // 模拟鼠标左键按下  
        private const int MOUSEEVENTF\_LEFTUP        = 0x0004;   // 模拟鼠标左键抬起  
        private const int MOUSEEVENTF\_RIGHTDOWN     = 0x0008;   // 模拟鼠标右键按下  
        private const int MOUSEEVENTF\_RIGHTUP       = 0x0010;   // 模拟鼠标右键抬起  
        private const int MOUSEEVENTF\_WHEEL         = 0x0800;   // 模拟鼠标滚轮  
        private const int MOUSEEVENTF\_MIDDLEDOWN    = 0x0020;   // 模拟鼠标中键按下  
        private const int MOUSEEVENTF\_MIDDLEUP      = 0x0040;   // 模拟鼠标中键抬起  
        private const int MOUSEEVENTF\_ABSOLUTE      = 0x8000;   // 标示是否采用绝对坐标 

        \[DllImport("user32")\]  
        private static extern int mouse\_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

        public static void move(int dx, int dy)  
        {  
            mouse\_event(MOUSEEVENTF\_MOVE, dx, dy, , );  
        }

        public static void absMove(int x, int y)  
        {  
            mouse\_event(MOUSEEVENTF\_ABSOLUTE | MOUSEEVENTF\_MOVE, , , , );  
        }

        public static void wheel(int roll)  
        {  
            mouse\_event(MOUSEEVENTF\_WHEEL, , , roll, );  
        }

        public static void leftSingle()  
        {  
            mouse\_event(MOUSEEVENTF\_LEFTDOWN | MOUSEEVENTF\_LEFTUP, , , , );  
        }

        public static void leftDouble()  
        {  
            mouse\_event(MOUSEEVENTF\_LEFTDOWN | MOUSEEVENTF\_LEFTUP, , , , );  
            mouse\_event(MOUSEEVENTF\_LEFTDOWN | MOUSEEVENTF\_LEFTUP, , , , );  
        }

        public static void right()  
        {  
            mouse\_event(MOUSEEVENTF\_RIGHTDOWN | MOUSEEVENTF\_RIGHTUP, , , , );  
        }

        public static void middle()  
        {  
            mouse\_event(MOUSEEVENTF\_MIDDLEUP | MOUSEEVENTF\_MIDDLEDOWN, , , , );  
        }  
    }
