Using C# To Return Data From PowerShell

问题

I am trying to return a PrimarySMTPAddress to a variable, in Powershell the code I run is this:

Get-Mailbox -identity UserName | select PrimarySMTPAddress

And it returns the correct value, I want to get this in my C# Code, I have done the following:

string getPrimarySMTP = "Get-Mailbox -identity " + username + "| select PrimarySMTPAddress";

var runSpace = RunspaceFactory.CreateRunspace(Utility.CreateConnectionInfo());
runSpace.Open();
var pipeline = runSpace.CreatePipeline();

pipeline.Commands.AddScript(getPrimarySMTP);
var primarySmtp = pipeline.Invoke();
runSpace.Dispose();

I would Expect this to return the same data, but it doesn't. I just get an exception:

The term 'select' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Is this the way to return values from a powershell command?

For what version of Exchange ? for 2010 up you need to use Remote Powershell see https://msdn.microsoft.com/en-us/library/office/ff326159%28v=exchg.150%29.aspx . (even in 2007 your code would work because you haven't loaded the snapin).

You may need to add an additional space character before the pipe. It' being concatenated to the username, with the resulting string becoming ... -identity UserName| select ..."

Here's the corrected statement:

string getPrimarySMTP = "Get-Mailbox -identity " + username + " | select PrimarySMTPAddress";

Thanks for asking this question, it helped me to lead to the answer I needed. My code resulted in the following using RemoteRunspace to an Exchange 2013 environment:

    try
    {
        var target = new Uri(Uri);
        SecureString PSPassword = new SecureString();
        foreach (char c in ConfigurationManager.AppSettings["Password"])
        {
            PSPassword.AppendChar(c);
        }
        //var cred = (PSCredential)null;
        PSCredential cred = new PSCredential(ConfigurationManager.AppSettings["Username"], PSPassword);
        WSManConnectionInfo connectionInfo = new WSManConnectionInfo(target, shell, cred);
        connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Default;
        connectionInfo.OperationTimeout = 1 * 60 * 1000; // 4 minutes.
        connectionInfo.OpenTimeout = 1 * 30 * 1000; // 1 minute.
        using (Runspace remoteRunspace = RunspaceFactory.CreateRunspace(connectionInfo))
        {
            remoteRunspace.Open();
            using (PowerShell powershell = PowerShell.Create())
            {
                powershell.Runspace = remoteRunspace;
                powershell.AddScript(PSSnapin);
                powershell.Invoke();
                powershell.Streams.ClearStreams();
                powershell.Commands.Clear();
                Pipeline pipeline = remoteRunspace.CreatePipeline();
                Command getMailBox = new Command("Get-Mailbox");
                getMailBox.Parameters.Add("Identity", Username);
                Command cmd = new Command("Select-Object");
                string[] Parameter = new string[] { "PrimarySMTPAddress" };
                cmd.Parameters.Add("Property", Parameter);
                pipeline.Commands.Add(getMailBox);
                pipeline.Commands.Add(cmd);
                Collection<PSObject> results = pipeline.Invoke();
                primarySMTPAddress = results[0].ToString();
                primarySMTPAddress = primarySMTPAddress.ToUpper().Replace("@{PRIMARYSMTPADDRESS=", "");
                primarySMTPAddress = primarySMTPAddress.ToUpper().Replace("}", "");
            }
            remoteRunspace.Close();
        }
        return primarySMTPAddress;
    }
    catch
    {
        return "Error";
    }

Hope this helps anyone in future.
