C# --- 如何在代码中开启进程

方法一

using (Process myProcess = new Process())
{
    myProcess.StartInfo.UseShellExecute = false;
    // You can start any process, HelloWorld is a do-nothing example.
    myProcess.StartInfo.FileName = "C:\\HelloWorld.exe";
    myProcess.StartInfo.CreateNoWindow = true;
    myProcess.StartInfo.Arguments = arguments
    myProcess.Start();
    // This code assumes the process you are starting will terminate itself.
    // Given that it is started without a window so you cannot terminate it
    // on the desktop, it must terminate itself or you can do it programmatically
    // from this application using the Kill method 
    //or give a timeout time as shown follow
    //myProcess.WaitForExit(1000)
}

方法二

var startInfo = new ProcessStartInfo()
{
    UseShellExecute = true,
    CreateNoWindow = false,
    FileName = exe,
    WindowStyle = ProcessWindowStyle.Hidden,
    WorkingDirectory = workDirectory,
    Arguments = arguments
};

using Process exeProcess = Process.Start(startInfo);
var completed = exeProcess != null && exeProcess.WaitForExit(1000);

Example — 使用进程运行nuget.exe, 下载一个Nuget library

var nugetExe = Path.Combine(exeDirectory, "lib/nuget.exe");
var cmd = $"install {MyNugetLibrary} -OutputDirectory \"{OutputFolder}\"";
var startInfo = new ProcessStartInfo()
{
    UseShellExecute = false,
    RedirectStandardError = true,
    CreateNoWindow = false,
    FileName = nugetExe,
    WindowStyle = ProcessWindowStyle.Hidden,
    WorkingDirectory = exeDirectory,
    Arguments = cmd
};
using (Process exeProcess = Process.Start(startInfo))
{
	var completed = exeProcess.WaitForExit(1000);
}
