Return a value from vbscript function in c#

Not to present production code, but to show

1. that/how it 'works in principle'
2. what keywords/components you have to look up in the docs

demo.cs:

using System;
using System.Diagnostics;

namespace Demo
{
    public class Demo
    {
        public static void Main(string [] args) {
            string user  = "nix";
            if (1 <= args.Length) {user = args[0];};
            string passw = "nix";
            if (2 <= args.Length) {passw = args[1];};
            string cscript = "cscript";
            string cmd = string.Format("\"..\\vbs\\auth.vbs\" {0} {1}", user, passw);
            System.Console.WriteLine("{0} {1}", cscript, cmd);

            Process process = new Process();
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.RedirectStandardOutput = true;
            process.StartInfo.CreateNoWindow = true;
            process.StartInfo.FileName = "cscript.exe";
            process.StartInfo.Arguments = cmd;
            try {
              process.Start();
              System.Console.WriteLine(process.StandardOutput.ReadToEnd());
              System.Console.WriteLine(process.ExitCode);
            } catch (Exception ex) {
              System.Console.WriteLine(ex.ToString());
            }
        }
    }
}

auth.vbs:

Option Explicit

Dim nRet : nRet = 2
If WScript.Arguments.Count = 2 Then
   If "user" = WScript.Arguments(0) And "passw" = WScript.Arguments(1) Then
      WScript.Echo "ok"
      nRet = 0
   Else
      WScript.Echo "fail"
      nRet = 1
   End If
Else
   WScript.Echo "bad"
End If
WScript.Quit nRet

output:

demo.exe
cscript "..\vbs\auth.vbs" nix nix
fail

1

demo.exe user passw
cscript "..\vbs\auth.vbs" user passw
ok

0

Perhaps you can simplify things by forgetting the text return and use the .Exitcode only.
