Can you please give me the detail code explanation.

I want to call the below PowerShell script from c# by using the same code.

what is a "list type" argument? could you give us an example? as long as you stick with `Process`, you're limited to a string. — Cee McSharpface, Mar 27 '18 at 10:44
List lsstr= new List(); if (IFS_startCb.Checked) { lsstr.Add("1"); } i want to send this value as argument. — Vamsi Krishna, Mar 27 '18 at 10:46

PowerShell powerShell = PowerShell.Create();

// Add and invoke your PS script

powerShell.AddCommand("Import-Module").AddParameter("Name",  "path\yourPSScript.ps1");
powerShell.Invoke();

powerShell.Commands.Clear();

//Add your function
powerShell.AddCommand("Server");

//Add attributes
powerShell.AddParameter("parameter1", value);
powerShell.AddParameter("parameter2", value);

//invoke
powerShell.Invoke();

Thanks Jens:) -- can i send list values to parameter 2 ... ??? can you help on this ? like what should i place in parameter1, parameter2 and value1 and value2. – Vamsi Krishna Mar 27 '18 at 13:03
I don't think PowerShell supports generic lists without including some .NET, but perhaps it could work with `param([System.Collections.Generic.List[string]]$lsstrt)` – Jens Tore Fremmegaard Mar 27 '18 at 13:19
