PowerShell variables and C#

Question

I'm working on Office 365 plugin in C# and trying this PowerShell command:

$newLicense = New-MsolLicenseOptions -AccountSkuId example:ENTERPRISEPACK -DisabledPlans SHAREPOINTWAC,MCOSTANDARD,SHAREPOINTENTERPRISE
Set-MsolUserLicense -UserPrincipalName test@example.com -AddLicenses "example:ENTERPRISEPACK" -LicenseOptions $newLicense

In PS, this works well. In C#, I'm having trouble to run this command. Here is my C# code, from PowerShellInvoker class:

var iss = InitialSessionState.CreateDefault();
iss.ImportPSModule(new[] { MsOnline });
iss.ThrowOnRunspaceOpenError = true;
_runspace = RunspaceFactory.CreateRunspace(iss);
_runspace.Open();
_invoker = new RunspaceInvoke(_runspace);

I've tried many ways:

scriptText_ = "$newLicense = New-MsolLicenseOptions -AccountSkuId {1} -DisabledPlans SHAREPOINTWAC,MCOSTANDARD,SHAREPOINTENTERPRISE\n"+
"Set-MsolUserLicense -UserPrincipalName test@example.com -AddLicenses \"example:ENTERPRISEPACK\" -LicenseOptions $newLicense");

I use this following method to execute other commands which works perfectly:

_invoker.Invoke(scriptText_);

And also:

var pipeline = _runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptText_);
return pipeline.Invoke(); // and getting back the variable

I also tried to add the variable in the Runspace object:

_runspace.SessionStateProxy.SetVariable ("newLicense", pipeline.Invoke());

But the command do not work, and returns no error. I don't really understand the PowerShell environment (I'm a beginner in this).

Thanks in advance for all the help you can provide.

I suspect you are encountering an error that the PowerShell engine isn't showing you. Try this approach instead to observe non-terminating errors:

var ps = PowerShell.Create();
ps.AddScript(@"Get-ChildItem c:\xyzzy");
var results = ps.Invoke();
if (ps.HadErrors)
{
    foreach (var errorRecord in ps.Streams.Error)
    {
        Console.WriteLine(errorRecord);
    }
}
foreach (var result in results)
{
    Console.WriteLine(result);
}
