Powershell command through C# code

Question

I want to add through C# code Powershell command or script (what is correct?) variable declaration with default value stored in C# variable. For example, in Powershell I typing following line

 $user = 'Admin'

I want to add this line in C# code.

powershell.AddScript(String.Format("$user = \"{0}\"", userName));

or

powershell.AddCommand(String.Format("$user = \"{0}\"", userName));

I try with AddCommand() but it throws exception. I use PS 2.0.

According to this article How to run PowerShell scripts from C#, you will need something like this:

// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();

Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(String.Format("$user = \"{0}\"", userName));
pipeline.Commands.AddScript("#your main script");

// execute the script
Collection<psobject> results = pipeline.Invoke();
// close the runspace
runspace.Close();
