Hi Olaf Reitz,
After running the command still i am getting same error,
The Windows PowerShell snap-in 'Microsoft.Exchange.Management.PowerShell.SnapIn' is not installed on this computer
please see below my task and i achieved so far.
i need to get list of Users in C# from Exchange Server. for that i  created new User [[email protected]]
in Exchange Server , then i give Full Access Permissions to that User to Access all other Mail Boxes.
By giving below command in PowerShell  I am getting all Users List . 
Get-Mailbox -ResultSize Unlimited
i need the same list In C# code. for that I
tried with below code.
 Here i got only particular user [ [email protected]] details , instead of list.
SecureString secureString = new SecureString();
string myPassword = "EIS2014!@#"; string username = "[email protected]";
foreach (char c in myPassword)
secureString.AppendChar(c);
PSCredential ExchangeCredentials = new PSCredential(username, secureString);
WSManConnectionInfo connectionInfo = new WSManConnectionInfo(new Uri("http://ExchangeServer.admin.com/powershell ), "http://schemas.microsoft.com/powershell/Microsoft.Exchange , ExchangeCredentials);
Runspace runspace = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace(connectionInfo);
runspace.Open();
string newCommand = "Get-Mailbox | Get-MailboxPermission";
Pipeline cmd = runspace.CreatePipeline(newCommand);
Collection<PSObject> results = cmd.Invoke();
runspace.Close();
so , i changed the code below
RunspaceConfiguration rsConfig = RunspaceConfiguration.Create();
PSSnapInException snapInException = null;
PSSnapInInfo info = rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.SnapIn", out snapInException);
Runspace myRunSpace = RunspaceFactory.CreateRunspace(rsConfig);
myRunSpace.Open();
Pipeline pipeLine = myRunSpace.CreatePipeline();
Command myCommand = new Command("Get-Mailbox -ResultSize Unlimited");
pipeLine.Commands.Add(myCommand);
Collection<PSObject> commandResults = pipeLine.Invoke();
i need Users list In C# , how can i achieve this ?
i am getting list in PowerShell , but i need it in C# code. 
Is Visual studio Compiled code  be 64 bit for running PowerShell scripts  ?
