I have a C# application that runs PowerShell scripts after reading them off database as strings. Assume script1, script2 and utilityfunctions are scripts read from database.
var rs = RunspaceFactory.CreateRunspace();
rs.Open();
var ps = PowerShell.Create();
ps.Runspace = rs;
ps.AddScript(utilityFunctions);
ps.AddScript(script1);
Is there anyway possible that I can call functions in utilityFuntions from script1? I have tried using $MyInvocation and go through its properties but did not find anything useful. When going through ps.Commands properties, I can of course see two items but when going through commands within the script, I cannot get to anything inside utilityFunctions. I guess I can read all scripts and concatenate them as string and only pass one script but I am just wondering if there is a way to do it without string concatenation.

I am trying to call PowerShell ISE Script from the C#.
I have command that I am running it on the PowerShell
. .\Commands.ps1; Set-Product -bProduct 'Reg' -IPPoint 'ServerAddress' -Location 'testlocation' -Terminal 3
Now I am trying to create the Command with the c# I have wrote some code Like this.
//Set Execution Policy to un restrict
powershell.AddCommand("Set-ExecutionPolicy");
powershell.AddArgument("unrestricted");
powershell.Invoke();
powershell.Commands.Clear();
powershell.AddScript("K:\\Auto\\Cases\\Location\\Commands.ps1", false);
powershell.AddArgument("Set-Product").AddParameter("bProduct ", "Reg").
AddParameter("IPPoint", "ServerAddress").
AddParameter("Location", "testlocation").AddParameter("Terminal", 3);
powershell.Invoke();
I can see its running fine. But its not updating values in my xml file. It suppose to update my values in file. When I try to run it with powershell It does run and works file. But c# code does not work.
Any hint or clue will be appreciated.
Mind the semicolon, so this is basically two statements:
1.) Dot-sourcing the script Commands.ps1
. .\Commands.ps1
2.) Invoking the cmdlet Set-Product
Set-Product -bProduct 'Reg' -IPPoint 'ServerAddress' -Location 'testlocation' -Terminal 3
So, you have to treat them as such. Also, AddScript expects code, not a file name.
powershell
// dot-source the script
.AddScript(#". 'K:\Auto\Cases\Location\Commands.ps1'")
// this is the semicolon = add another statement
.AddStatement()
// add the cmdlet
.AddCommand("Set-Product")
.AddParameter("bProduct", "Reg")
.AddParameter("IPPoint", "ServerAddress")
.AddParameter("Location", "testlocation")
.AddParameter("Terminal", 3)
// invoke all statements
.Invoke();
(Alternatively to AddStatement() you can of course split this up in two calls and call Invoke() twice.)
Is there way to convert invoked powershell command from C# to string?.
Let's say for example i have something like this:
PowerShell ps = PowerShell.Create();
ps.AddCommand("Add-VpnConnection");
ps.AddParameter("Name", "VPN_" + ClientName);
ps.AddParameter("ServerAddress", VPN_SERVER_IP);
ps.AddParameter("AllUserConnection");
ps.AddParameter("SplitTunneling", true);
ps.AddParameter("TunnelType", "L2tp");
And i would like to save invoked command to log file.
Can i somehow return whole command as string?
I believe what you want essentially is this.
PowerShell ps = PowerShell.Create();
ps.AddScript($"Add-VpnConnection -Name \"VPN_{ClientName}\" -ServerAddress {VPNServerIP} -AllUserConnection -SplitTunneling -TunnelType L2tp");
ps.Invoke();
The invoke return will contain a collection of PSObject so you can read it and save the information like you want in a log in c#.
Note: This answer does not solve the OP's problem. Instead, it shows how to capture a PowerShell command's output as a string in C#, formatted in the same way that the command's output would print to the display (console), if it were run in an interactive PowerShell session.
Out-String is the cmdlet that produces formatted, for-display representations of output objects as strings, as they would print to the screen in a PowerShell console.
Therefore, you simply need to use another .AddCommand() in order to pipe the output from your Add-VpnConnection call to Out-String:
string formattedOutput;
using (PowerShell ps = PowerShell.Create())
{
ps.AddCommand("Add-VpnConnection")
.AddParameter("Name", "VPN_" + ClientName)
.AddParameter("ServerAddress")
.AddParameter("AllUserConnection", VPN_SERVER_IP)
.AddParameter("SplitTunneling", true)
.AddParameter("TunnelType", "L2tp");
// Add an Out-String call to which the previous command's output is piped to.
// Use a -Width argument (column count) large enough to show all data.
ps.AddCommand("Out-String").AddParameter("Width", 512);
// Due to use of Out-String, a *single string* is effectively returned,
// as the only element of the output collection.
formattedOutput = ps.Invoke<string>()[0];
}
Console.Write(formattedOutput);
I'm trying to make a simple (or so i thought) app that will make it easier to launch .ps1 scripts, so that non-powershell savvy users can use them.
Here is how its supposed to look like
Now, i managed to figure out one part about running scripts:
private string RunPowershell_1(string skripta)
{
StringBuilder stringBuilder = new StringBuilder();
foreach (string str in PowerShell.Create().AddScript(skripta).AddCommand("Out-String").Invoke<string>())
{
stringBuilder.AppendLine(str);
}
return stringBuilder.ToString();
}
But i would normally run scripts that require parameters, so i would like to be able to read list of parameters from the script i import, assign value to them and then run the scrip (output should go to either txtPreview or to a file).
Is there a way to do this?
If there is another (better) approach to this I'm all ears.
You can use this powershell command to get the list of parameters.
(get-command get-netadapter).Parameters
And this is how you can read its output in C#:
using (PowerShell ps = PowerShell.Create())
{
ps.AddScript("...");
Collection<PSObject> output = ps.Invoke();
}
C# code (Source):
private string RunScript(string scriptText)
{
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptText);
// add an extra command to transform the script
// output objects into nicely formatted strings
// remove this line to get the actual objects
// that the script returns. For example, the script
// "Get-Process" returns a collection
// of System.Diagnostics.Process instances.
pipeline.Commands.Add("Out-String");
// execute the script
Collection<psobject /> results = pipeline.Invoke();
// close the runspace
runspace.Close();
// convert the script result into a single string
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
return stringBuilder.ToString();
}
Powershell code
#Dummy code for example purpose
ASNP Quest*
#Example of cmdlet I want to use
$Users = Get-QADGroupMember -Identity $Group -Enabled
return $Users.count
As you can see, my goal is to call the script utilizing RunScript above in a Button_Click event in my WPF app. I've been able to correctly call the script but the call to Quest cmdlets clearly doesn't go trough as wanted since I would receive 0 in the above example.
TL;DR
Script is running correctly but calls to Quest cmdlets don't work since it return nothing (or 0 in the above example). Is there something I'm missing ?
EDIT
Important to note that the exact same script ran in Powershell returns the correct values. Calling it from C# don't.
I wonder if you could help me being gods of the C# world and all!
I'm pretty new to C# and i think im a bit out of my depth, but i am trying to use C# to create a wpf that will ask the user for parameters and then pass these parameters to my script to perform an install.
At the moment i have it set to click a button to begin the install as that was requested (no idea why) so on button click i have the following.
string script = System.IO.File.ReadAllText(#"C:\my\script\path\script.ps1");
using (Runspace runspace = RunspaceFactory.CreateRunspace())
{
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.Runspace.SessionStateProxy.SetVariable("SiteCode", GlobalVariables.sitecode);
ps.AddScript(script);
ps.Invoke();
}
My first problem is i need to set the script file location using partially a variable that has been set earlier in the form
Now this i can probably do myself, but calling the powershell script and then setting variables that are used within the powershell script from variables that are declared in the C# form are a bit out of my depth, am i on the right line here? do i look like a complete idiot or should i go bang my head on a tree outside?
Thanks very much in advance for any help you can offer!
