进程在启动后立即停止(Process stops immediately after start)

 希望您能够帮助我。 我正在使用MonoDevelop编写Raspberry Pi。 
 
 我想用C＃执行一个python脚本并从中读取。 
 
class Program 
{
    public static void Main(string[] args)
    {
        Process p = new Process();
        p.OutputDataReceived += new DataReceivedEventHandler(OutputHandler);
        p.StartInfo.FileName = "sudo";
        p.StartInfo.Arguments = "python gpio.py";
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.CreateNoWindow = true;
        p.StartInfo.RedirectStandardOutput = true;

        p.Start();
        p.BeginOutputReadLine();
        p.WaitForExit();
    }

    private static void OutputHandler(Object sender, DataReceivedEventArgs args) 
    {
        Console.WriteLine(args.Data);
    }
}
 
 在调试时我可以看到进程已退出Click for image 
 
 但是在TaskManager中我可以看到，该进程仍在运行。 脚本也控制gpio引脚。 并且脚本控制引脚（Led on / off），即使“Process has exited”也是如此。 但我从redirectOutput得到任何东西。 
 
 为什么进程在启动后立即退出（脚本有一段时间为真。它不应该停止）？ 这是执行脚本的正确方法吗？ 
 如果我从终端执行Python脚本，它可以正常工作。 它不应该是脚本的错误。 如果我启动一个进程，例如FileName“libreoffice”，它也可以。 
 
 该脚本位于“/ bin / Debug /”（文件夹）中的项目文件夹中。为任何人设置执行权限。 
 
 谢谢， 
 问候 

Hope you can help me. I'm coding on a Raspberry Pi with MonoDevelop.
 
I want to execute a python script with C# and read from it.
 
class Program 
{
    public static void Main(string[] args)
    {
        Process p = new Process();
        p.OutputDataReceived += new DataReceivedEventHandler(OutputHandler);
        p.StartInfo.FileName = "sudo";
        p.StartInfo.Arguments = "python gpio.py";
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.CreateNoWindow = true;
        p.StartInfo.RedirectStandardOutput = true;

        p.Start();
        p.BeginOutputReadLine();
        p.WaitForExit();
    }

    private static void OutputHandler(Object sender, DataReceivedEventArgs args) 
    {
        Console.WriteLine(args.Data);
    }
}
 
While Debugging i can see that the Process has exited Click for image
 
But in the TaskManager i can see, that the process is still running. Also the script controls the gpio pins. And the script controlls the pins (Led on/off), even if the "Process has exited" . But I dont get anything from redirectOutput.
 
Why does the Process immediately quits after starting (the script has a while true. it shouldn't stop)? Is this the right way to execute a script?
 If I execute the Python script from the terminal, it works fine. It shouldn't be an error with the script. If I start a process e.g. FileName "libreoffice", it works too.
 
The script is located in the project folder in "/bin/Debug/" (the folder) Permissions for execution are set for anyone.
 
Thanks,
 Greetings
