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
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 downWM_LBUTTONUP = 0x202,   //Left mousebutton upWM_LBUTTONDBLCLK = 0x203, //Left mousebutton doubleclickWM_RBUTTONDOWN = 0x204, //Right mousebutton downWM_RBUTTONUP = 0x205,   //Right mousebutton upWM_RBUTTONDBLCLK = 0x206, //Right mousebutton doWM_CUT = 0x300,WM_COPY = 0x301,WM_PASTE = 0x302,WM_CLEAR = 0x303}public enum Functions : int{KEYEVENTF_KEYDOWN = 0x0000, // New definitionKEYEVENTF_EXTENDEDKEY = 0x0001, //Key down flagKEYEVENTF_KEYUP = 0x0002, //Key up flagVK_LCONTROL = 0xA2, //Left Control key codeA = 0x41, //A key codeC = 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;
