Executing 3rd Party Powershell SDK commands with C#

This is an incredibly frustrating problem that nobody else seems to have the answer to so I'm trying to break my question down into the simplest thing possible. Surely there are other 3rd party Powershell SDK's out there that people have tried to access and use via C#. Does anybody know why this would get an error saying the following?

The term 'add-PSSnapin Citrix*.Admin.V* is not recognized as the name of a cmdlet, function, script file, or operable program.

The same goes for other commands that this PSSnapin provides at the command prompt.

I can type this command in manually at a powershell command prompt and it works. So do the other commands. What's the deal?

public void testPS()
        {
            using (Runspace runspace = RunspaceFactory.CreateRunspace())
            {
                runspace.Open();
                PowerShell ps = PowerShell.Create();
                ps.Runspace = runspace;
                ps.AddCommand("add-PSSnapin Citrix.*.Admin.V*");
                ps.Invoke();
                //Commented sections below don't work either, same error. 
                //ps.AddCommand("Get-BrokerSession");
                //ps.AddParameter("AdminAddress");
                //ps.AddParameter("SERVERNAME");
                //ps.Invoke();
                //Collection<PSObject> psr = ps.Invoke();
                //foreach (PSObject x in psr)
                //{
                //    MessageBox.Show(x.ToString());
                //}
            }
        }

UPDATE:

This new code as suggested in the answer below gets a new error: 'System.Management.Automation.ParameterBindingException' occurred in System.Management.Automation.dll

public void testPS()
        {
            using (Runspace runspace = RunspaceFactory.CreateRunspace())
            {
                runspace.Open();
                PowerShell ps = PowerShell.Create();
                ps.Runspace = runspace;
                PSSnapInException psex;
                runspace.RunspaceConfiguration.AddPSSnapIn("Citrix.Broker.Admin.V2", out psex);
                Pipeline pipeline = runspace.CreatePipeline();

                Command getSession = new Command("Get-BrokerSession");
                getSession.Parameters.Add("AdminAddress");
                getSession.Parameters.Add("MYSERVERNAME");
                //also tried the above with this code
                //getSession.Parameters.Add("-AdminAddress MYSERVERNAME");
                // and
                //getSession.Parameters.Add("AdminAddress MYSERVERNAME");
                // and other methods as well
                pipeline.Commands.Add(getSession);

                //This line below is where the exception occurs.
                Collection<PSObject> output = pipeline.Invoke();

                foreach (PSObject x in output)
                {
                    MessageBox.Show(x.ToString());
                }
            }
        }

UPDATE 2:

I also get this same error above trying to set the execution policy.

UPDATE 3:

Fixed, see comments in answer below. The syntax of the parameters line was incorrect.

For those still stuck with this like me, even as of the latest Microsoft.Powershell.Sdk 6.2.0 nuget package I was running into this issue. A colleague of mine ended up getting it to work by doing the following:

    public string RunPowershell(string param1)
    {
        var outputString = "";

        var startInfo = new ProcessStartInfo
        {
            FileName = @"powershell.exe",
            Arguments = "C:\\path\\to\\script.ps1" + " -param1  " + param1,
            RedirectStandardOutput = true,
            RedirectStandardError = true,
            UseShellExecute = false,
            CreateNoWindow = true
        };

        using (var process = new Process())
        {
            process.StartInfo = startInfo;
            process.Start();

            var output = process.StandardOutput.ReadToEnd();
            var errors = process.StandardError.ReadToEnd();

            if (!string.IsNullOrEmpty(output))
            {
                outputString = output;
            }

            if (!string.IsNullOrEmpty(errors))
            {
                Console.WriteLine($"Error: {errors}");
            }
        }

        return outputString;
    }

"C:\path\to\script.ps1" can have Add-PSSnapin commands in it and still run just fine.

I couldn't find a bug filed for Microsoft.Powershell.Sdk to handle this, but if someone creates one and links it here, thanks!

Hope this helps

Use RunspaceConfiguration.AddPSSnapIn to add PSSnapin and then add a command:

        Runspace runSpace = RunspaceFactory.CreateRunspace();
        runSpace.Open();
        PSSnapInException psex;
        runSpace.RunspaceConfiguration.AddPSSnapIn("Citrix.Broker.Admin.V2", out psex);
        Pipeline pipeline = runSpace.CreatePipeline();

        Command getSession = new Command("Get-BrokerSession");
        getSession.Parameters.Add("AdminAddress", "SERVERNAME");
        pipeline.Commands.Add(getSession);

        Collection<PSObject> output = pipeline.Invoke();

You need to make sure that you split the command from its argument. In your case, it would be something like:

ps.AddCommand("add-PSSnapin");

Then you can always just post-append Citrix.*.Admin.V* as an argument for the command above.
