Powershell addscript and invoke from C# not displaying result on command line

I've the below powershell script file

C:\user\deskptop\script1.ps1

The contents of the script is just the below:

get-process

i'm trying to create a C# console app to get the output of this script on console. When i execute the script outside C# it runs fine but when i execute it inside C# it doesn't produce anything. i'm trying use addscript and invoke.

C# code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Management.Automation;
using System.Collections.ObjectModel;


namespace InvokePowerShellScriptFrmCsharp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string script = @"C:\\Users\\Desktop\\script1.ps1";


            PowerShell shell = PowerShell.Create();

            shell.AddScript(script);
            //shell.AddCommand("get-process");

            shell.Invoke();
            //shell.AddScript(script).Invoke();

            Collection<PSObject> pSObjects = shell.Invoke();

            foreach (PSObject p in pSObjects)
            {
                Console.WriteLine(p.ToString());
            }
            Console.WriteLine("Press any key to continue");
            Console.ReadLine();
        }
    }
}

When i execute the above i get the console with 'Press any key to continue' but no output before that.

but if i just try the below i get the result

shell.addcommand("get-process");

I want to get this working with addscript coz in the future if there is more than one command in the powershell script then i need to be able to execute the script from C# for desired results.

i've tried many links to try research but don't seem to be getting it to work.

Try loading the script contents first, then passing that to the AddScript method:

string script = File.ReadAllText(@"C:\Scripts\script1.ps1");
