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);
