Inserting a PowerShell command into c#

Question

I want to use this PowerShell command in a C# project:

Get-VM -Name Win8-Henry | Get-VMNetworkAdapter | Select MacAddress

This is what I normally do in c#:

public static void MacAdd(string machineName,Runspace run) {
    // Get-VM -Name Win8-Henry | Get-VMNetworkAdapter | Select MacAddress
    Command command = new Command("Get-VM");
    command.Parameters.Add("Name", machineName);

    using (Pipeline hostPipeline = run.CreatePipeline())
    {
        hostPipeline.Commands.Add(command);
        Collection<PSObject> echos = hostPipeline.Invoke();
        hostPipeline.Stop();
    }
}

What I need help with is adding the second command, and then using the pipeline.

hostPipeline.Commands.Add(anotherCommand) and then Invoke() ? — NValchev

Use the AddScript() method on the PowerShell class.

var Command = String.Format("Get-VM -Name {0} | Get-VMNetworkAdapter | Select MacAddress", computername);
var PowerShell = PowerShell.Create();
PowerShell.AddScript(Command);
PowerShell.Invoke();

Just add the other commands to the pipeline too :)

hostPipeline.Commands.Add(new Command("Get-VMNetworkAdapter"));

Just to share what I do when I have a script that I need to execute in an application. I can then replace the parameters (i.e., "$!$machineName$!$" easily and get the result cleanly.

Dim lxScript As XElement = <Script>
.{
Get-VM -Name $!$machineName$!$ | Get-VMNetworkAdapter | Select MacAddress
}                         
                     </Script>
