I'm trying to write some C# code to interact with Lync using PowerShell, and I need to import the Lync module before executing the Lync cmdlets. However, my code doesn't seem to import the module and I keep getting a "get-csuser command not found" exception. Here is my code:
PowerShell ps = PowerShell.Create();
ps.AddScript(#"import-module Lync");
ps.Invoke();
ps.Commands.AddCommand("Get-csuser");
foreach (PSObject result in ps.Invoke())
{
Console.WriteLine(result.Members["Name"].Value);
}
Any idea how can I import the Lync module?
Got it, the module needs to be imported by its full path, and also the execution policy for both 64-bit powershell and 32-bit powershell need to be set to Unrestricted (or anything other than restricted depending on your case). Here's the code:
static void Main(string[] args)
{
InitialSessionState initial = InitialSessionState.CreateDefault();
initial.ImportPSModule(new string[] {"C:\\Program Files\\Common Files\\Microsoft Lync Server 2010\\Modules\\Lync\\Lync.psd1"} );
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.Commands.AddCommand("Get-csuser");
foreach (PSObject result in ps.Invoke())
{
Console.WriteLine(result.Members["Identity"].Value);
}
}
Try to use the PowerShell class AddCommand method.
ps.AddCommand("import-module Lync");
Or you can use the Runspace class, you can find an example here : http://www.codeproject.com/Articles/18229/How-to-run-PowerShell-scripts-from-C

I know we can can run physical powershell script from c# but how to create powershell script file itself dynamically based on input params.
Kindly suggest.
you can execute powershell script/ commands directly from your c# project.
you'll need to add a reference to system.managment.automation dll in project's references.
example:
function that will take script as a string , execute it and then returns a result:
private string RunScript(string script)
{
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
Pipeline pipline = runspace.CreatePipeline();
pipline.Commands.AddScript(script);
pipline.Commands.Add("Out-String");
Collection<PSObject> results = pipline.Invoke();
runspace.Close();
StringBuilder stringBuilder = new StringBuilder();
foreach(PSObject pSObject in results)
{
stringBuilder.AppendLine(pSObject.ToString());
}
return stringBuilder.ToString();
}
function call be like:
Console.WriteLine(RunScript("Your Powershell Script"));

Hi I'm trying to execute the Get-ClusterGroup cmdlet from C# 4.0. I've used the following code
InitialSessionState iss = InitialSessionState.CreateDefault();
iss.ImportPSModule(new string[] { "failoverclusters"});
Runspace myRunSpace = RunspaceFactory.CreateRunspace(iss);
myRunSpace.Open();
Pipeline pipeLine = myRunSpace.CreatePipeline();
Command myCommand = new Command("Get-ClusterGroup");
pipeLine.Commands.Add(myCommand);
Console.WriteLine("Invoking Command");
Collection commandResult = pipeLine.Invoke();
foreach (PSObject resultObject in commandResult)
{
Console.WriteLine(resultObject.ToString());
}
myRunSpace.Close();
But getting the following error
The term 'Get-ClusterGroup' 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.
It will be great if someone can show me the where I'm missing the logic or where is the problem in my code
Get-ClusterGroup is a Powershell Commandlet, not an .exe file. You can invoke Powershell commands from .NET using the System.Management.Automation.PowerShell class, as described on MSDN here: http://msdn.microsoft.com/en-us/library/system.management.automation.powershell(v=vs.85).aspx
I'm attempting to execute a SQL Query from within Powershell, within C#. I have been successful in doing so with ActiveDirectory cmdlets and wanted to take it one step further.
My first issue is while the following format works with ActiveDirectory (and in the ISE) it fails in C#:
using (PowerShell pS = PowerShell.Create())
{
pS.AddCommand("import-module");
pS.AddArgument("sqlps");
pS.Invoke();
}
I've long since had the security set to Unrestricted, but the error I'm getting is:
CmdletInvocationException was unhandled
File C:\Program Files (x86)\Microsoft SQL Server\110\Tools\PowerShell\Modules\sqlps\Sqlps.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170.
However, if I run like this I get no error, though a later "Get-Module -all" call shows no sign of the module:
using (PowerShell pS = PowerShell.Create())
{
pS.AddScript("Import-Module sqlps");
pS.Invoke();
}
If I then try importing the ActiveDirectory module and calling Get-Module, it shows nothing.
What's going on here?
I'm not that great with C sharp but when calling scripts from outside of powershell there is a flag when executing the program to bypass the execution policy, i.e.
powershell.exe -executionpolicy bypass -command "& '\\somepath\somescript.ps1' "
This allows remote scripts to be called, as even with unrestricted set I still found that it wanted to prompt for the execution of some scripts so for instance in the task scheduler it would simply fail to run.
Also when importing SQLPS I've also found it's useful to add the -DisableNameChecking flag, you may also want to push your location beforehand and pop it afterwards otherwise you will end up in the SQLPS PSdrive with no access to local locations if you need it.
Did you try something like this?
PowerShell ps = PowerShell.Create();
ps.AddScript("set-executionpolicy unrestricted -scope process");
ps.AddScript("import-module sqlps");
ps.AddScript("get-module sqlps");
var m = ps.Invoke();
foreach (var mm in m.Select(x => x.BaseObject as PSModuleInfo))
Console.WriteLine(new { mm.Name, mm.Version });
I had a similar issue with the sqlServer ps module. Looks like when executing from C# you need to load the modules manually into the runspace in order for this to work.
string scriptText = File.ReadAllText("yourScript.ps1");
//This is needed to use Invoke-sqlcommand in powershell. The module needs to be loaded into the runspace before executing the powershell.
InitialSessionState initial = InitialSessionState.CreateDefault();
initial.ImportPSModule(new string[] { #"SqlServer\SqlServer.psd1" });
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
using (PowerShell psInstance = PowerShell.Create())
{
psInstance.Runspace = runspace;
psInstance.AddScript(scriptText);
var PSOutput = psInstance.Invoke();
}
Also add all the references located in the SqlServer.psd1. This file is usually found in "C:\Program Files\WindowsPowerShell\Modules\SqlServer". I added to folder to my solution to be able to execute on remote servers.
You need to add Microsoft.SqlServer.BatchParser.dll reference in order to execute invoke-sqlcommand from the Powershell.
You should be able to do the same for sqlps module. Rather use SqlServer as it is newer.
I need to start a powershell script from C# and get the PSSSecurityException on pipeline.Invoke()
AuthorizationManager check failed.
My code:
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
using (Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration))
{
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
Command scriptCommand = new Command(scriptfile);
pipeline.Commands.Add(scriptCommand);
pipeline.Invoke();
}
Questions
I suspect that I need to set PSCredential. But I can not promt for it, so I have to handle this in code. Can this be done in a secure way? (This was not the case)
Check out this SuperUser post: https://superuser.com/questions/106360/how-to-enable-execution-of-powershell-scripts
You probably just need to allow unsigned scripts to run. In the PS console, type the following:
set-executionpolicy remotesigned
Another resource echoes this: http://tgnp.me/2011/09/powershell-authorizationmanager-check-failed-resolution/
Give that a try and let me know what happens.
To capture the output from the script, try this:
Collection output = pipeline.Invoke();
foreach (PSObject psObject in output)
{
<here you can ToString the psObject for the output and write it line by line to your log>
}
The problem was that the script was placed on a share. To run scripts on this share I needed to add the share to Trusted Sites.
