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();

AddScriptmethod instead?
