c# open runspace in background

Question

I am trying to find a way into c#. The following program takes one argument as input, opens a runspace and invokes the argument, e.g. "powershell ls". Now I would like to have the program do its work in the background and not block the command line interface while it is executing so I could run two instances of it at the same time. What is the way to get there, if any? Can I somehow "fork" that runspace?

using System;  
using System.Text;  
using System.Management.Automation;  
using System.Management.Automation.Runspaces;  
using System.Collections.ObjectModel;  
  
namespace runspace  
{  
    internal class Program  
    {  
  
        static void Main(string[] args)  
        {  
  
            void invokeCommand(string command)  
            {  
                Runspace runspace = RunspaceFactory.CreateRunspace();  
                runspace.Open();  
                RunspaceState state = runspace.RunspaceStateInfo.State;  
                Console.WriteLine("Runspace State = " + state);  
  
                Pipeline pipeline = runspace.CreatePipeline();  
                pipeline.Commands.AddScript(command);  
                Collection<PSObject> results = pipeline.Invoke();  
                 
                runspace.Close();  
                //List<PSObject> results = pipeline.Invoke().ToArray().ToList();  
                StringBuilder stringBuilder = new StringBuilder();  
                foreach (PSObject obj in results) { stringBuilder.AppendLine(obj.ToString()); }  
                String output = stringBuilder.ToString();  
                Console.WriteLine(output);  
                Console.WriteLine("Ende");  
            }  
  
            invokeCommand(args[0]);  
  
            //Console.ReadLine();  
        }  
    }  
}

@p3ppi , Welcome to Microsoft Q&A, you could refer to the following code to open two instances of runspace in background.

code.txt

Tested result:

The first argument is used to get the current files information of the current folder, the second argument is used to get the current date.

Best Regards,
