How to supply parameters to powershell script (System.Management.Automation.Powershell)?

I have a need to run PowerShell scripts from C# application. I like using method AddScript for this. And it works quite nice. However, it does not seem to work as expected when I added parameters to script with method AddParameters.
Here is test payload (PowerShell):
param ([string]$Arg1, [string]$Arg2, [switch]$ArgParamless)
$filename = "payload_with_params.txt"
$filepath = $env:temp
$fullpath = Join-Path -Path $filepath -ChildPath $filename
$dt = Get-Date -Format "yyyy.MM.dd HH:mm:ss"
$val = $dt+' '+$Arg1+' '+$Arg2+' '+$ArgParamless
Add-Content -Path $fullpath -Value "$val"
It works just fine if I push it from PS like this:
.\payload_with_params.ps1 -Arg1 "Bla 1" -Arg2 "Bla 2" -ArgParamless
Result:
2023.01.19 16:58:10 Bla 1 Bla 2 True
The C# code (oversimplified):
string command = File.ReadAllText(pathToPS1);
List<CommandParameter> paramList = new List<CommandParameter>();
paramList.Add(new CommandParameter("Arg1", "Bla 1"));
paramList.Add(new CommandParameter("Arg2", "Bla 2"));
paramList.Add(new CommandParameter("ArgParamless"));
using (PowerShell ps = PowerShell.Create())
{
//Adding script file content to object
ps.AddScript(command);
if (paramList != null)
{
if (paramList.Count > 0)
{
//Adding Params to object;
ps.AddParameters(paramList);
}
}
//Launching
ps.Invoke();
}
And the result:
2023.01.19 16:54:00 System.Management.Automation.Runspaces.CommandParameter System.Management.Automation.Runspaces.CommandParameter False
So.. it's not working as I expected. How should I supply parameters to script?

For [switch] parameters, you'll want to bind a bool - PowerShell will interpret true as "Present" and false as "Absent":
paramList.Add(new CommandParameter("ArgParamless", true));

Well, it turns out AddParameter(CommandParameter) approach doesn't work.
This approach is working:
string command = File.ReadAllText(pathToPS1);
using (PowerShell ps = PowerShell.Create())
{
//Adding script file content to object
ps.AddScript(command);
if (paramList != null)
{
if (paramList.Count > 0)
{
//Adding Params to object;
ps.AddArgument("-Arg1 XXXXXX");
}
}
//Launching
ps.Invoke();
}
On PowerShell end this arguments can be extracted for usage from $args array:
$arglist = $args -join " "
Even better approach using hashtable:
string command = File.ReadAllText(pathToPS1);
using (PowerShell ps = PowerShell.Create())
{
//Adding script file content to object
ps.AddScript(command);
if (paramList != null)
{
if (paramList.Count > 0)
{
//Adding Params to object;
var hashtable = new Hashtable {
{ "Arg1", "XXXXXX" },
{ "Arg2", "YYYYYY" },
{ "ArgParamless", true }
};
ps.AddArgument(hashtable);
}
}
//Launching
ps.Invoke();
}
And that's what you do on PS side to use it:
function Wrapper-Test ([string]$Arg1, [string]$Arg2, [switch]$ArgParamless) {
$Result = $Args1+' '+$Args2+' '+$ArgParamless
return $Result
}
$MyArgs = "";
$MyArg = $args[0]
$MyArgs = Wrapper-Test #MyArg;
$filename = "payload_with_params.txt"
$filepath = $env:temp
$fullpath = Join-Path -Path $filepath -ChildPath $filename
$dt = Get-Date -Format "yyyy.MM.dd HH:mm:ss"
$arglist = $args -join " "
$val = $dt + " " + $MyArgs
Add-Content -Path $fullpath -Value "$val"

WPF UI passing output from powershell function into textbox

I am creating a WPF UI and I am having trouble getting the output from a foreach loop within a function into a WPF textbox. The variables I need to output ar $id $newValue and $serviceName
#Iteration through services perform string replacement
ForEach ($Response in $Responses ) {
$id = $Response.id
$newValue = $Response.value.Replace("\Service", "")
$serviceName = $Response.serviceName
Write-Output $id
Write-Output $serviceName
Write-Output $newValue
#if statement here for testing this should be removed
if ($id -eq ) {
$Payload = #{
hostName = '';
hostOperatingSystem = 0;
optionalFilter1 = '';
optionalFilter2 = '';
description = '';
serviceName = $serviceName;
sectionName = "Services";
signature = 'null';``
value = $newValue
} | ConvertTo-Json -Depth 10
#Service Configuration API PUT method call to update fullpath value
$newURI = $URI + '/' + $id
$Response = Invoke-RestMethod -Uri $newURI -Method PUT -Headers $Headers -Body $Payload -ContentType 'application/json'
}
#here for testing this should be removed
else {
$output.text = "Nothing to do"
}
}
$output.text = "Done!"
}
[xml]$Form = Get-Content "MainWindow.xaml"
$NR = (New-Object System.Xml.XmlNodeReader $Form)
$Win = [Windows.Markup.XamlReader]::Load($NR)
$URL = $win.FindName("URL")
$cid = $win.FindName("Client_ID")
$csecret = $win.FindName("Client_Secret")
$update = $Win.FindName("Update")
$output = $Win.FindName("output")
$update.Add_Click( {
$UserAuthRoute = $URL.text
$client_id = $cid.text
$client_secret = $csecret.text
if ($UserAuthRoute -eq "" -or $client_secret -eq "" -or $client_secret -eq "") {
[System.Windows.MessageBox]::Show("Please enter in all values","Variables Required")
}else{
UpdateServices $UserAuthRoute $client_id $client_secret
$output.text += "Service ID:"+$id , "Service Name: "+$serviceName, "$newValue"
}
})
$Win.ShowDialog() ```

The solution was to append the value and separate with a newline
$output.text += "Service ID: " + $id + "`r`n" + "Service Name: " + $serviceName + "`r`n" + "Service Value: " + $newValue + "`r`n"

IO FileStream and StreamReader in Powershell return null while in c# it does work

I created a script in C# and for personnal reasons, I would like to convert it in PowerShell.
After many tries, I still can't understand why it still gave me this error, is there something wrong with the code ?

You are misunderstanding System.IO.StreamReader as $IOFile. You have to first declare it inside the $reader like this:
$reader = New-Object -TypeName System.IO.StreamReader -ArgumentList $filePath
In powershell .NET Types are called like this:
[System.IO.File]
Their static methods are called by placing two colons after ].

Create SSRS Data Driven Subscription using PowerShell

Edit: Added the whole converted c# to PowerShell with issue
I'm trying to convert MSDN C# code to PowerShell script.
Here's the MSDN link
I almost finished the conversion but I encounter some issues for my last line.
This is the complete error message: Exception calling "CreateDataDrivenSubscription" with "7" argument(s): "There was an error generating the XML document."
Below is the code snippet for the 7th argument in creating data driven subscription.
Here's the PowerShell script:
$Parameters | Add-Member -type NoteProperty -Name $EMPID.ParameterName -Value $EMPID.FieldAlias
$ReportYear = New-Object $ParameterValue
$ReportYear.Name = "ReportYear"
$ReportYear.Value = "2017"
$Parameters | Add-Member -type NoteProperty -Name $ReportYear.Name -Value $ReportYear.Value
$ReportMonth = New-Object $ParameterValue
$ReportMonth.Name = "ReportMonth"
$ReportMonth.Value = "6"
$Parameters | Add-Member -Type NoteProperty -Name $ReportMonth.Name -Value $ReportMonth.Value
$SubscriptionID = $objWebServerProxy.CreateDataDrivenSubscription($Report,$Settings,$arrDataRetrievalPlan,$Description,$EventType,$MatchData,$Parameters)
Here's the C# code
ParameterValueOrFieldReference[] parameters = new ParameterValueOrFieldReference[3];
ParameterFieldReference empID = new ParameterFieldReference(); // Data-driven.
empID.ParameterName = "EmpID";
empID.FieldAlias = "EmpID";
parameters[0] = empID;
ParameterValue reportYear = new ParameterValue();
reportYear.Name = "ReportYear";
reportYear.Value = "2004";
parameters[1] = reportYear;
ParameterValue reportMonth = new ParameterValue();
reportMonth.Name = "ReportMonth";
reportMonth.Value = "6"; // June
parameters[2] = reportMonth;
try
{
string subscriptionID = rs.CreateDataDrivenSubscription(
report, settings, dataRetrieval, description, eventType, matchData, parameters);
Can you tell me where did I miss on the conversion?

I'm not sure if the way you're creating the ParameterValue instances works - I can't tell for sure since the $ParameterValue declaration is missing, but chances are this causes the problem.
You might want to try something more along the lines of this:
$reportServerUri = "http://localhost/reportserver/ReportService2010.asmx?wsdl"
$rs = New-WebServiceProxy -Uri $reportServerUri -UseDefaultCredential -Namespace "SSRS"
# Note the difference, here we use the type generated when creating the webservice proxy:
$ReportYear = New-Object SSRS.ParameterValue
$ReportYear.Name = "ReportYear"
$ReportYear.Value = "2017"
See my blog post here for a quick tutorial.
Edit
To pinpoint which argument of CreateDataDrivenSubscription the error is, try substituting one or more arguments with $null - sure it might be invalid according to the method's documentation, but the null checks only occur once the call has been successfully sent to the server and deserialized.
In other words, if substituting the $Parameters argument with $null does not throw the "error generating XML document", then the error is in the $Parameters argument:
$SubscriptionID = $objWebServerProxy.CreateDataDrivenSubscription($Report,$Settings,
$arrDataRetrievalPlan,$Description,$EventType,$MatchData,$null)

running powershell with parameters in c# and writting those parameters in Text File
