Question

I would like to have a console app that is passed in a arg to be able to call itself passing in the same command arg that was sent in initially.

If I try this however

static void Main(string[] args)
{
    Assembly ass = System.Reflection.Assembly.GetExecutingAssembly();
    string cmd = Environment.CommandLine;

    Process again = new Process();
    again.StartInfo.FileName = ass.Location;
    again.StartInfo.Arguments = args[0];
    Console.WriteLine("Running with: " + args[0]);
    System.Threading.Thread.Sleep(10000);
    again.Start();
    return;
}

The initial call print “running with: Argument1” but the second call fails because the args array is empty.

Works for me. I compiled exactly this code:

using System;
using System.Diagnostics;
using System.Reflection;

class Test
{
    static void Main(string[] args)
    {
        Assembly ass = System.Reflection.Assembly.GetExecutingAssembly();
        string cmd = Environment.CommandLine;

        Process again = new Process();
        again.StartInfo.FileName = ass.Location;
        again.StartInfo.Arguments = args[0];
        Console.WriteLine("Running with: " + args[0]);
        System.Threading.Thread.Sleep(1000);
        again.Start();
        return;
    }
}

Using the command line:

csc Test.cs

And then ran it as:

Test.exe hello

… and it started extra processes recursively, each of which printed “Running with: hello”.
