C#客户端程序调用外部程序的3种实现方法

Window wnd = Window.GetWindow(this); //获取当前窗口
var wih = new WindowInteropHelper(wnd); //该类支持获取hWnd
IntPtr hWnd = wih.Handle;    //获取窗口句柄
var result = ShellExecute(hWnd, "open", "需要打开的路径如C:\Users\Desktop\xx.exe", null, null, (int)ShowWindowCommands.SW_SHOW);

[DllImport("shell32.dll")]
public static extern IntPtr ShellExecute(IntPtr hwnd, //窗口句柄
 string lpOperation, //指定要进行的操作
 string lpFile,  //要执行的程序、要浏览的文件夹或者网址
 string lpParameters, //若lpFile参数是一个可执行程序，则此参数指定命令行参数
 string lpDirectory, //指定默认目录
 int nShowCmd   //若lpFile参数是一个可执行程序，则此参数指定程序窗口的初始显示方式(参考如下枚举)
 );
