从后面的代码启动命令行 exe (ngrok) 的正确方法

Question

Im tryng to sart ngrok from a WPF C# app.

The desired result would be windows command line opening and ngrok starting up as if I had manually started it.

Im getting an exception: System.InvalidOperationException

private async void StartNgrok()
    {
        string ExePath = "C:\\Users\\mmcca\\ngrok.exe";
        string Args = "\"http 55678 -host-header=\"localhost: 55678\"";

        try
        {
            var proc = Process.Start(ExePath, Args);
        }
        catch (Exception ex)
        {
            // Throwing - System.InvalidOperationexception
        }

What is the correct way to start a command line exe from code behind?

Answer 1

You could try declaring ngrok as a Process, and then starting it this way - this has worked for me in the past:

Process ngrok = new Process();
ngrok.StartInfo.FileName   = "C:\\Users\\mmcca\\ngrok.exe";
ngrok.StartInfo.Arguments = "\"http 55678 -host-header=\"localhost: 55678\"";
ngrok.Start();

Let me know how you get on with this.
