How to call PowerShell cmdlets from C# in Visual Studio

Question

I'm creating a PowerShell cmdlets from Visual Studio and I can't find out how to call cmdlets from within my C# file, or if this is even possible? I have no trouble running my cmdlets one by one, but I want to set up a cmdlet to run multiple cmdlets in a sequel.

Answer 1

Yes, you can call cmdlets from your C# code.

You'll need these two namespaces:

using System.Management.Automation;
using System.Management.Automation.Runspaces;

Open a runspace:

Runspace runSpace = RunspaceFactory.CreateRunspace();
runSpace.Open();

Create a pipeline:

Pipeline pipeline = runSpace.CreatePipeline();

Create a command:

Command cmd= new Command("APowerShellCommand");

You can add parameters:

cmd.Parameters.Add("Property", "value");

Add it to the pipeline:

pipeline.Commands.Add(cmd);

Run the command(s):

Collection output = pipeline.Invoke();
foreach (PSObject psObject in output)
{
   ....do stuff with psObject (output to console, etc)
}

Does this answer your question?
