run powershell from c# application - c#

Hello a have a file with 21 lines of code in power shell. I need a way to run this file with a button in c#. I use c# in Visual Studio 2010. Please let me know if there is a way to achieve.
// Powershell
$Proc = Get-Process | Sort-Object CPU -Descending
$cores = Get-WmiObject Win32_processor
$memory = Get-WmiObject Win32_OperatingSystem
$Total = 10
$num = 1
Clear-Content c:\scripts\prueba.txt
foreach ($objItm in $Proc) {
If ($num -gt $Total) {
break #break the loop
}
[string] $strID=[System.Convert]::ToString($objItm.ID)
[string] $strProcessName=[System.Convert]::ToString($objItm.ProcessName)
[string] $strCPU=[System.Convert]::ToString($objItm.CPU)
[string] $strNUM=[System.Convert]::ToString($num)
$info=$strNUM+"-"+$strID+"-"+$strProcessName+"-"+$strCPU
$num += 1
$info|Add-Content c://scripts/prueba.txt
}
//Code c#
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open(); RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.Add(scriptFile)
Execute PowerShell script results = pipeline.Invoke();
I need for example press a button and make the script happens

You can use PS2EXE by Ingo Karstein
This creates a c# executable with it's own powershell host and with your script embedded.
I have a c# project which takes the c# code in PS2EXE, adds ability to read the contents of an encrypted powershell script, decrypt it and run it.

some tips that works for me . My application is already working
Run Visual Studio with permissions of Administrator this to avoid get a error with the Hkey_Local...
In power shell run this get-executionpolicy to view the policy and set unregistered with set-executionpolicy unregistered. This avoid any restriction by the OS.
And with the code write above the app work. Get ready and test !!!

Powershell Invoke() returning zero in C# for bolt command run

I'm able to run puppet bolt command in powershell. In powershell, I got output as below
Started on winrm://remotemachine
Finished on winrm://remotemachine
STDOUT:
RemoteMachineHostName
Successful on 1 target Run on 1 tartget in 3.2 sec
My C# is as below
PowerShell ps = PowerShell.Create();
ps.AddScript("C:\\User1\\GetRemoteAzureVMHostName.ps1");
Collection<PSObject> results = ps.Invoke(); // in results, I'm getting value as 0.
foreach (PSObject result in results)
{
//Do something
}
I tried changing build platform target to x64 in Visual Studio 2019 but it didn't worked.
How to fix above issue
Update 1:
I have used below command in powershell script.
bolt command run hostname --targets winrm://158.28.0.546 --no-ssl-verify --user testuser123 --password test#84p
It seems you cannot input the path of the PowerShell to the method AddScript(). Here is an example that runs the PowerShell script through C#:
private static string script =File.ReadAllText(#"Path\Sum.ps1");
private static void CallPS1()
{
using (Runspace runspace = RunspaceFactory.CreateRunspace())
{
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.AddScript(script);
ps.Invoke();
foreach (PSObject result in ps.Invoke())
{
Console.WriteLine("CallPS1()");
Console.WriteLine(result);
}
}
}
So you can try to read the script out and then input them in the method AddScript().
I figured it out that, Visual Studio is calling 32 bit powershell and unable to run bolt commands as bolt module installed on 64 bit powershell.
I have changed project build platform to x64 and build it.
It worked.

Windows Server 2012 - Access to registry denied when running powershell scripts from C#

I'm building a C# application that has to run some powershell scripts.
While the application works well on all my colleagues computers, I have issue having it to work properly on a Windows Server 2012 virtual machine.
Whenever I run a script through the application I'm getting the following error message:
Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option. To change the execution policy for the current user, run "Set-ExecutionPolicy -Scope CurrentUser".
I precise that I went through a LOT of topics and tried many things that did not solve my problem
I tried:
set-executionpolicy unrestricted
set-executionpolicy unrestricted -Scope -CurrentUser
And of course I ran these commands on both x64 and x86 powershell instances (running the powershell application as administrator)
Now the strange part is that I have no trouble running the script through the powershell window directly, the error only occurs when running the script through the C# application.
Here's the code involved:
public static List<string> RunPowerShellScript(Sequence sq, Script script)
{
try
{
script.Results = new List<Result>();
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
RunspaceInvoke runspaceInvoker = new RunspaceInvoke(runspace);
//runspaceInvoker.Invoke("set-executionpolicy bypass");
runspaceInvoker.Invoke("set-executionpolicy unrestricted");
//Create a pipeline to send variables
Pipeline pipeline = runspace.CreatePipeline();
//Create a command
Command myCommand = new Command(Properties.Settings.Default.Scripts + "\\" + script.ScriptName + ".ps1", false);
foreach (Parameter p in script.Parameters)
{
CommandParameter param = new CommandParameter(p.ParameterName, sq.GetUpdatedParameter(p));
myCommand.Parameters.Add(param);
}
pipeline.Commands.Add(myCommand);
//Return the output from the script
Collection<PSObject> returnObjects = pipeline.Invoke();
runspace.Close();
List<string> output = new List<string>();
foreach (PSObject po in returnObjects)
{
if (po != null)
output.Add(po.ToString());
}
return output;
}
catch(Exception e)
{
return new List<string> { e.Message, "1" };
}
}
To resolve this issue, Open powershell as an administrator and run the command again:
Set-ExecutionPolicy Unrestricted
may be this can solve your problem:
1- open "Visual Studio" az administrator
2- open your project solution with visualstudio
3- run it

PowerShell commandlet getting invoked but not responding

Invoke-MyFunction is a commandlet I wrote that takes an input file, changes it, and creates a new output file at a specified location. If I open a PowerShell on my desktop, import MyCommandlet.ps1, and run
Invoke-MyFunction -InputPath path\to\input -OutputPath path\to\output
everything works as expected. But when I try to import and invoke the command from a C# program with the code below, the commandlet doesn't run, doesn't log output, and doesn't produce the output file. It doesn't throw a CommandNotFoundException, so I assume the PowerShell object recognizes my commandlet. But I can't figure out why it doesn't execute it.
//set up the PowerShell object
InitialSessionState initial = InitialSessionState.CreateDefault();
initial.ImportPSModule(new string[] { #"C:\path\to\MyCommandlet.ps1" });
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
//have MyFunction take input and create output
ps.AddCommand("Invoke-MyFunction");
ps.AddParameter("OutputPath", #"C:\path\to\output");
ps.AddParameter("InputPath", #"C:\path\to\input");
Collection<PSObject> output = ps.Invoke();
Further, after invoking MyFunction, the PowerShell object ps fails to execute any other commands. Even known ones.
This works for me:
//set up the PowerShell object
var initial = InitialSessionState.CreateDefault();
initial.ImportPSModule(new string[] { #"C:\Users\Keith\MyModule.ps1" });
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
//have MyFunction take input and create output
ps.AddCommand("Invoke-MyFunction");
ps.AddParameter("OutputPath", #"C:\path\to\output");
ps.AddParameter("InputPath", #"C:\path\to\input");
var output = ps.Invoke();
foreach (var item in output)
{
Console.WriteLine(item);
}
With a MyModule.ps1 of:
function Invoke-MyFunction($InputPath, $OutputPath) {
"InputPath is '$InputPath', OutputPath is '$OutputPath'"
}
One thing that did cause me a failure is that on Visual Studio 2013 (maybe 2012 as well) AnyCPU apps will actually run 32-bit on a 64-bit OS. You have to have set the execution policy for PowerShell x86 to allow script execution. Try opening up a PowerShell x86 shell in admin mode and run Get-ExecutionPolicy. If it is set to Restricted, use Set-ExecutionPolicy RemoteSigned to allows scripts to execute.

How to use ActiveDirectory module (RSAT tools) in c#

I want to use specific command that are provided by the "Active Directory Administration with Windows PowerShell". So I installed this module on my server.
Now, I want to use these commands in my code. My project is in c# - ASP.NET.
Here's the code I use to call traditional "cmdlet" command (New-Mailbox, Set-User, ...) :
string runasUsername = #"Mario";
string runasPassword = "MarioKart";
SecureString ssRunasPassword = new SecureString();
foreach (char x in runasPassword)
ssRunasPassword.AppendChar(x);
PSCredential credentials =
new PSCredential(runasUsername, ssRunasPassword);
// Prepare the connection
var connInfo = new WSManConnectionInfo(new Uri("MarioServer"),
"http://schemas.microsoft.com/powershell/Microsoft.Exchange",credentials);
connInfo.AuthenticationMechanism =
AuthenticationMechanism.Basic;
connInfo.SkipCACheck = true;
connInfo.SkipCNCheck = true;
// Create the runspace where the command will be executed
var runspace = RunspaceFactory.CreateRunspace(connInfo);
//Params
....
// create the PowerShell command
var command = new Command("New-Mailbox");
command.Parameters.Add("Name", name);
....
// Add the command to the runspace's pipeline
runspace.Open();
var pipeline = runspace.CreatePipeline();
pipeline.Commands.Add(command);
// Execute the command
var results = pipeline.Invoke();
if (results.Count > 0)
System.Diagnostics.Debug.WriteLine("SUCCESS");
else
System.Diagnostics.Debug.WriteLine("FAIL");
runspace.Dispose();
This code work perfectly ! Great ! But let say I want to use "Set-ADUser", this command is from ActiveDirectory module (RSAT tools).
Given that all is set on the server (the module is installed), I tried to simply change "New-Mailbox" for "Set-ADUser" :
var command = new Command("Set-ADUser");
When I run the code, I have this error :
The term 'Set-ADUser' is not recognized as the name of a cmdlet, function, script file, or operable program.
So, that's my question :
How can we run command from the ActiveDirectory module (RSAT tools) in c# ? (Im using VS 2010).
As #JPBlanc pointed out in the comments section, you will need to ensure that the ActiveDirectory PowerShell module is loaded. PowerShell version 3.0 and later have module auto-loading enabled by default (it can be disabled), but if you're still targeting PowerShell 2.0, then you must first call:
Import-Module -Name ActiveDirectory;
.. before you can use the commands inside the module.
For the purposes of validation, you can use the Get-Module command, to ensure that the ActiveDirectory module has been imported.
Get-Module -Name ActiveDirectory;
If the above command returns $null, then the module is not imported. To verify that PowerShell can "see" the ActiveDirectory module, without actually importing it, run this command:
Get-Module -Name ActiveDirectory -ListAvailable;

The term ' ' is not recognized as the name of a cmdlet,

I have a PowerShell script stored in a file, MergeDocuments.ps1. When I run the script from the Windows PowerShell command prompt it runs fine
.\MergeDocuments.ps1 1.docx 2.docx merge.docx
Calling the script from a Windows console application also runs fine.
When I tried calling the script from an Asp.Net web service, I faced some issues regarding registry access. I used impersonation and gave permission to Network Service account to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell to solve this problem
Next I faced issue about PowerShell being unable to create objects of type OpenXmlPowerTools.DocumentSource[], so I added the following to my script
Add-Type -Path "C:\Users\Administrator\Documents\WindowsPowerShell\Modules\OpenXmlPowerTools\OpenXmlPowerTools.dll"
Import-Module OpenXmlPowerTools
Now the current problem is that I am getting the error "The term 'Merge-OpenXmlDocument' is not recognized as the name of a cmdlet, ..."
How can I solve that?
PowerShell Script
Add-Type -Path "C:\Users\Administrator\Documents\WindowsPowerShell\Modules\OpenXmlPowerTools\OpenXmlPowerTools.dll"
Import-Module OpenXmlPowerTools
# The last argument is the path of the merged document
$noOfSourceDocs = ($($args.length) - 1)
# Create an array to hold all the source documents
[OpenXmlPowerTools.DocumentSource[]] $docs = New-Object OpenXmlPowerTools.DocumentSource[] $noOfSourceDocs
for ($i = 0; $i -lt $noOfSourceDocs; $i++)
{
$docs[$i] = New-Object -TypeName OpenXmlPowerTools.DocumentSource -ArgumentList $args[$i]
$docs[$i].KeepSection = 1
}
Merge-OpenXmlDocument -OutputPath $args[-1] -Sources $docs
Webservice .Net Code
using (new Impersonator(username, domain, password))
{
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
RunspaceInvoke invoker = new RunspaceInvoke(runspace);
invoker.Invoke("Set-ExecutionPolicy Unrestricted");
// create a pipeline and feed it the script file
Pipeline pipeline = runspace.CreatePipeline();
Command command = new Command(ConfigurationManager.AppSettings["PowerShellScript"]);
foreach (var file in filesToMerge)
{
command.Parameters.Add(null, file);
}
command.Parameters.Add(null, outputFilename);
pipeline.Commands.Add(command);
pipeline.Invoke();
runspace.Close();
}
Can you just try to install OpenXmlPowerTools module in the PowerShell System module path :
C:\Windows\system32\WindowsPowerShell\v1.0\Modules
