在没有源程序的情况时，如何通过控制鼠标按钮控制电脑exe程序？

有时候想控制第三方软件，但是没有源程序，可以控制鼠标键盘自动操作软件达到我们想要的目的

首先建一个功能类包含窗口控制，鼠标控制和输入控制等

csharp 复制代码 
```csharp
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

namespace 进程程序名
{
    public class Win32Api
    {

        [DllImport("user32.dll", SetLastError = true)]
        static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool SetForegroundWindow(IntPtr hWnd);

        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);

        [DllImport("user32.dll", SetLastError = true)]
        public static extern bool PostMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);

        [DllImport("user32.dll", SetLastError = true)]
        public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

        public static IntPtr FindWindowByCaption(string caption)
        {
            return FindWindow(null, caption);
        }
        public static IntPtr FindWindowByClassName(string className)
        {
            return FindWindow(className, null);
        }
    }

    public enum SW
    {
        HIDE = 0,
        SHOW_NORMAL = 1,
        SHOW_MINIMIZED = 2,
        MAXIMIZE = 3,
        SHOW_MAXIMIZED = 3,
        SHOW_NO_ACTIVE = 4,
        SHOW = 5,
        MINIMIZE = 6,
        SHOW_MIN_NO_ACTIVE = 7,
        SHOW_NA = 8,
        RESTORE = 9,
        SHOW_DEFAULT = 10,
        FORCE_MINIMIZE = 11
    }
    public enum WMessages : int
    {
        WM_KEYDOWN = 0x100,
        WM_KEYUP = 0x101,
        WM_CHAR = 0x102,
        WM_LBUTTONDOWN = 0x201, //Left mousebutton down
        WM_LBUTTONUP = 0x202,   //Left mousebutton up
        WM_LBUTTONDBLCLK = 0x203, //Left mousebutton doubleclick
        WM_RBUTTONDOWN = 0x204, //Right mousebutton down
        WM_RBUTTONUP = 0x205,   //Right mousebutton up
        WM_RBUTTONDBLCLK = 0x206, //Right mousebutton do
        WM_CUT = 0x300,
        WM_COPY = 0x301,
        WM_PASTE = 0x302,
        WM_CLEAR = 0x303
    }


    public enum Functions : int
    {
        KEYEVENTF_KEYDOWN = 0x0000, // New definition
        KEYEVENTF_EXTENDEDKEY = 0x0001, //Key down flag
        KEYEVENTF_KEYUP = 0x0002, //Key up flag
        VK_LCONTROL = 0xA2, //Left Control key code
        A = 0x41, //A key code
        C = 0x43, //C key code
    }

}

再写一个实际应用，根据实际软件大小和位置设置相应的控制点位
