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 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  using System; using System.Collections.Generic; using System.Collections.Specialized; using System.Diagnostics; using System.Drawing; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;  namespace 进程程序名 {     public class 进程程序名     {         public Process 进程程序名         {             get => Process.GetProcessesByName("进程程序名").FirstOrDefault(i => i.MainWindowHandle != IntPtr.Zero);          }          public void SendMsg(string msg)         {             if(SunnyLink==null)             {                 Console.WriteLine("请打开SunnyLink窗口，之后重试！");                 return;             }             if(string.IsNullOrEmpty(msg))             {                 Console.WriteLine("发送的字符为空！");
