Trouble with calling PS script (with parameter) from C#

I am trying to setup a simple .aspx web page that will accept a user's input of a string (later, more than one string) and use that string as the parameter value for a Powershell script.
The PS script looks like this right now:
[CmdletBinding()]
param (
[string] $ServiceName
)
$ServiceName | out-file c:\it\test.txt
$ServiceName | Out-String
The C# code looks like this:
var shell = PowerShell.Create();
// Add the script to the PowerShell object
shell.Commands.AddScript("C:\\it\\test.ps1 -ServiceName BITS");
// Execute the script
var results = shell.Invoke();
When I run that, I get "BITS" written to the test.txt file. What I need to do now, is setup the application to call the script, passing in the "ServiceName" parameter. I found this: Call PowerShell script file with parameters in C# and tried the following code:
PowerShell ps = PowerShell.Create();
ps.AddScript(#"c:\it\test.ps1").AddParameter("ServiceName", "BITS");
var results = ps.Invoke();
In this case, the script was called and the test.txt file was created, but the value (BITS) was not written to the file. What am I missing here? Why isn't the parameter being passed to the script?
Thanks.

I ended up using
var ps = #"C:\it\test.ps1";
processInfo = new ProcessStartInfo("powershell.exe", "-File " + ps + " -ServiceName BITS);
I don't like this as much, but it works. shrug

Here are three possible solutions for future readers including me:
using (PowerShell ps = PowerShell.Create())
{
//Solution #1
//ps.AddCommand(#"C:\it\test.ps1", true).AddParameter("ServiceName", "BITS");
//Solution #2
//ps.AddScript(#"C:\it\test.ps1 -ServiceName 'BITS'", true);
//Solution #3
ps.AddScript(File.ReadAllText(#"C:\it\test.ps1"), true).AddParameter("ServiceName", "BITS");
Collection<PSObject> results = ps.Invoke();
}
I haven't seen solution #3 documented anywhere else, though I got the idea for it from https://blogs.msdn.microsoft.com/kebab/2014/04/28/executing-powershell-scripts-from-c/

Exchange Powershell in c#

I have a bunch of powershell commands within c# however one is returning 0 results and I just cant figure it out, so with the power of the internet I am hoping you guys have an answer.
My c# code running the power is as follows
internal static List<ExchangeMailboxes> ExchangeMailboxList(string snapIn)
{
List<ExchangeMailboxes> data = new List<ExchangeMailboxes>();
StringBuilder stringBuild = new StringBuilder();
stringBuild.AppendLine("$script:WarningPreference = 'SilentlyContinue'");
stringBuild.AppendLine(
"Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,#{name='TotalItemSize';expression={[math]::Round((($_.TotalItemSize.Value.ToString()).Split('(')[1].Split(' ')[0].Replace(',','')/1GB),2)}},#{name='TotalDeletedItemSize';expression={[math]::Round((($_.TotalDeletedItemSize.Value.ToString()).Split('(')[1].Split(' ')[0].Replace(',','')/1GB),2)}}");
using (PowerShell inst = PowerShell.Create())
{
inst.AddScript("Add-PSSnapin " + snapIn)
.AddScript(stringBuild.ToString());
Collection<PSObject> results = inst.Invoke();
foreach (PSObject obj in results)
{
data.Add(new ExchangeMailboxes()
{
Name = obj.Members["DisplayName"].Value.ToString(),
InboxSize = obj.Members["TotalItemSize"].Value.ToString(),
DeletedSize = obj.Members["TotalDeletedItemSize"].Value.ToString()
});
}
}
return data;
}
I can confirm that the snapin is loading correctly and if I run the powershell command manually it is all fine and I con confirm there are no rights issues
here is the powershell command in its raw format
Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,#{name='TotalItemSize';expression={[math]::Round((($_.TotalItemSize.Value.ToString()).Split('(')[1].Split(' ')[0].Replace(',','')/1GB),2)}},#{name='TotalDeletedItemSize';expression={[math]::Round((($_.TotalDeletedItemSize.Value.ToString()).Split('(')[1].Split(' ')[0].Replace(',','')/1GB),2)}}

The recommended way to interact with Exchange 2010 and newer is to open a session to http://servername/powershell using the microsoft.exchange configuration:
$ExSession = New-PSSession –ConfigurationName Microsoft.Exchange –ConnectionUri ‘http://ExServer1.contoso.com/PowerShell/?SerializationLevel=Full’ -Credential $Credentials –Authentication Kerberos
I've never tried remoting from c# code, but I guess it shouldn't be any different than what your doing now (except for the powershell code itself, of course). Since you're interacting with various "size" attributes in Exchange, it is still recommended to have the management tools installed locally, otherwise those values don't serialize/deserialize properly (you'll find other posts on serverfault on that topic).

Powershell SQLPS module not importing within C#

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.

Powershell Pipe and Foreach-Object in c#

I am invoking a get-msoluser cmdlet of office365 and i use the following cmdlet in powershell
Get-MsolUser -UserPrincipalName user#organization.onmicrosoft.com | ForEach-Object{ $_.licenses}
The output is a collection of licenses and i wanted the same script to be run in c#. so i have written the code as follows
private void displayLicenses(){
Command cmd = new Command("Get-MsolUser");
cmd.Parameters.Add("UserPrincipalName","user#organization.onmicrosoft.com");
Command cmd2 = new Command("ForEach-Object");
cmd2.Parameters.Add("$_.licenses.AccountSku");
Pipeline pipe = Office365Runspace.CreatePipeline();
pipe.Commands.Add(cmd);
pipe.Commands.Add(cmd2);
Console.WriteLine("Before invoking the pipe");
ICollection<PSObject> result = pipe.Invoke();
CheckForErrors(pipe);
Console.WriteLine("Executed command {0} + {1} with no error", cmd.CommandText, cmd2.CommandText);
foreach(PSObject obj in result){
foreach(PSPropertyInfo propInfo in obj.Properties){
Console.WriteLine(propInfo.Name+": "+propInfo.Value+" "+propInfo.MemberType);
}
}
}
But i still get an error on executing this function saying
Unhandled Exception:
System.Management.Automation.CommandNotFoundException: The term
'ForEach-Object' is not recognized as the name of a cmdlet, function,
scrip t file, or operable program. Check the spelling of the name, or
if a path was in cluded, verify that the path is correct and try
again.
I checked that my project has a reference to System.management.Automation.dll file that contains the ForEach-Object cmdlet.
I found the dll using this cmd in powershell
(Get-Command ForEach-Object).dll

I figured out the problem causing for the issue. It is due to the misconfigured runspace i created.
InitialSessionState initalState = InitialSessionState.Create();
initalState.ImportPSModule(new String[] { "msonline" });
//initalState.LanguageMode = PSLanguageMode.FullLanguage;
Office365Runspace = RunspaceFactory.CreateRunspace(initalState);
Office365Runspace.Open();
i was creating the initalstate with empty one,When i changed it to default one it worked fine.On creating the default one it includes all the modules that were obtained by default.
InitialSessionState initalState = InitialSessionState.CreateDefault();
it worked fine.
Thanks,
Satya

It sounds like your're trying to run that in the remote session at the Exchange server. Those are NoLanguage constrained sessions, meaning that you can only run the Exchange cmdlets in those sessions. If you want to use PowerShell core language cmdlets (like foreach-object), you have to do that in a local session and either use Import-PSSession to import the Exchange functions into your local session (implicit remoting) , or use Invoke-Command and point it at the remote session on the Exchange server.

C# execute Powershell

So a while back I wrote a Powershell script that would Parse an IIS Log and then do some stuff (email, create a report, and other nifty stuff). Well I am working on excuting that from a C# console app. Before I post my code I just wanted to make one thing clear, i would like to try and stay away from log parser to parse this log cause of many reasons but one specifically, why use something when you can write something else to your liking ;). So here is my code
PS Script:
$t1 =(get-date).AddMinutes(-10)
$t2 =$t1.ToUniversalTime().ToString("HH:mm:ss")
$IISLogPath = "C:\inetpub\logs\LogFiles\W3SVC1\"+"u_ex"+(get-date).AddDays(-3).ToString("yyMMdd")+".log"
$IISLogFileRaw = [System.IO.File]::ReadAllLines($IISLogPath)
$headers = $IISLogFileRaw[3].split(" ")
$headers = $headers | where {$_ -ne "#Fields:"}
$IISLogFileCSV = Import-Csv -Delimiter " " -Header $headers -Path $IISLogPath
$IISLogFileCSV = $IISLogFileCSV | where {$_.date -notlike "#*"}
$tape = $IISLogFileCSV | Format-Table time,s-ip,cs-uri-stem | Out-Host
C# app thus far:
Runspace runSpace = RunspaceFactory.CreateRunspace();
runSpace.Open();
Pipeline pipeline = runSpace.CreatePipeline();
pipeline.Commands.AddScript(#"D:\PS-Scripts\IIS\IISLogScan.ps1");
Collection<PSObject> results = pipeline.Invoke();
foreach (PSObject obj in results)
{
Console.WriteLine(results);
}
Console.ReadLine();
Now when I run my App it just sits and doesnt display anything and i Set my breakpoints and it says that there is nothing to display within my foreach which i am completely hung up on cause running my ps1 script it works perfectly and shows many lines. Any insight anyone can give would be great.

Try changing in .ps1 file:
$global:tape =$IISLogFileCSV | Format-Table time,s-ip,cs-uri-stem
and in c#
pipeline.Commands.AddScript(#"D:\PS-Scripts\IIS\IISLogScan.ps1");
pipeline.Commands.AddScript("$tape");
pipeline.Commands.AddScript("out-string");
or in .ps1:
$tape =$IISLogFileCSV | Format-Table time,s-ip,cs-uri-stem
$tape
and in c#
pipeline.Commands.AddScript(#"D:\PS-Scripts\IIS\IISLogScan.ps1");
pipeline.Commands.AddScript("out-string");
