HOW TO: Call .PS1 script from Managed code using Remote Powershell(Exchange 2010)

As promised below is the code to call a .PS1 script and pass parameters to it. Most of the code is very similar to my previous post that showed how to call Exchange & PowerShell cmdlet.

using System;
using System.Collections.Generic;
using System.Text;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
using System.Management.Automation.Remoting;
using System.Collections.ObjectModel;
using System.Security;

namespace CallingScriptPS
class Program
static void Main(string[] args)
string password = "Password";
string userName = "Domain\\Administrator";
System.Uri uri = new Uri("http://CAS-SERVER/powershell?serializationLevel=Full");
System.Security.SecureString securePassword = String2SecureString(password);

System.Management.Automation.PSCredential creds = new System.Management.Automation.PSCredential(userName, securePassword);

Runspace runspace = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace();

PowerShell powershell = PowerShell.Create();
PSCommand command = new PSCommand();
command.AddParameter("ConfigurationName", "Microsoft.Exchange");
command.AddParameter("ConnectionUri", uri);
command.AddParameter("Credential", creds);
command.AddParameter("Authentication", "Default");
PSSessionOption sessionOption = new PSSessionOption();
sessionOption.SkipCACheck = true;
sessionOption.SkipCNCheck = true;
sessionOption.SkipRevocationCheck = true;
command.AddParameter("SessionOption", sessionOption);

powershell.Commands = command;

// open the remote runspace

// associate the runspace with powershell
powershell.Runspace = runspace;

// invoke the powershell to obtain the results
Collection<PSSession> result = powershell.Invoke<PSSession>();

foreach (ErrorRecord current in powershell.Streams.Error)
Console.WriteLine("Exception: " + current.Exception.ToString());
Console.WriteLine("Inner Exception: " + current.Exception.InnerException);

if (result.Count != 1)
throw new Exception("Unexpected number of Remote Runspace connections returned.");

// Set the runspace as a local variable on the runspace
powershell = PowerShell.Create();

command = new PSCommand();
command.AddParameter("Name", "ra");
command.AddParameter("Value", result[0]);
powershell.Commands = command;
powershell.Runspace = runspace;

// First import the cmdlets in the current runspace (using Import-PSSession)
powershell = PowerShell.Create();
command = new PSCommand();
command.AddScript("Import-PSSession -Session $ra");
powershell.Commands = command;
powershell.Runspace = runspace;

// Now run get-ExchangeServer
System.Collections.ObjectModel.Collection<PSObject> results = new System.Collections.ObjectModel.Collection<PSObject>();

powershell = PowerShell.Create();
powershell.Runspace = runspace;

//Change the Path to the Script to suit your needs
System.IO.StreamReader sr = new System.IO.StreamReader("..\\..\\Script.ps1");
powershell.Runspace.SessionStateProxy.SetVariable("proc", "C*");
powershell.Runspace.SessionStateProxy.SetVariable("mbx", "*MBX");

results = powershell.Invoke();

if (powershell.Streams.Error.Count > 1)
foreach (ErrorRecord er in powershell.Streams.Error)
foreach (PSObject ps in results)
// dispose the runspace and enable garbage collection
runspace = null;

// Finally dispose the powershell and set all variables to null to free
// up any resources.
powershell = null;

private static SecureString String2SecureString(string password)
SecureString remotePassword = new SecureString();
for (int i = 0; i < password.Length; i++)

return remotePassword;


Below is what the Script.PS1 looks like:

get-process |where {$_.Name -like $proc}
get-exchangeserver | Where {$_.Name -like $mbx}

The two parameters that we pass in are called “proc” & “mbx”.

Note:This code will not work if we do not call the New-PSSession & the Import-PSSession cmdlet’s for reasons explained in my previous post.
