Defining Variable for Powershell script in C# winforms

Question

Im trying to run a ps script with this code

 private void materialButton3_Click(object sender, EventArgs e)
    {
        using (PowerShell pshell = PowerShell.Create())
        {
            string path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
            pshell.AddCommand("Zuordnung.ps1");
            pshell.Invoke();
        }
    }

from this thread in a c# winforms app

the ps script includes:

$Destination = "\\path1\"
Get-ChildItem "\\path2" | ForEach-Object {
    $Tail = ($_.BaseName -split '_')[-2]
    $Filter = "*_{0}" -f $Tail
    $DestDir = Get-ChildItem $Destination -Filter $Filter -Directory | Select-Object -ExpandProperty FullName -First 1
    if ($DestDir) {
        Copy-Item $_.FullName $DestDir -Force
    } else {
        "No Directory was found that matched the Filter {0} in Directory {1}" -f $Filter, $Destination | Write-Host
    }

Path1 and Path2 are supposed to be pulled off textboxes

pshell.AddParameter("Path1", "C:\somepath")

is looking good but im trying to set them dynamic e.g.

pshell.AddParameter(@"$Destination", {textbox1.text}

textbox1.text gets its value from a folder browser dialog

im also trying

 SessionState.PSVariable.Set("source", {guna2TextBox4.Text});
SessionState.PSVariable.Set("$source", {guna2TextBox4.Text});
SessionState.PSVariable.Set($@"source", {guna2TextBox4.Text});

Is there an elegant way to solve this?

Thanks in advance

Use [`pshell.AddParameters`](https://learn.microsoft.com/en-us/dotnet/api/system.management.automation.powershell.addparameters?view=powershellsdk-7.0.0) [as documented](https://learn.microsoft.com/en-us/powershell/scripting/developer/hosting/adding-and-invoking-commands?view=powershell-7.2#addparameter). Also I think you want `AddCommand` not `AddScript` — Charlieface, Jan 04 '22 at 12:10
no, i dont get how to assign a certain value to the ps variables — BlackArch.py, Jan 04 '22 at 14:53
ive updated the question, im trying to set textbox.text string as $destination — BlackArch.py, Jan 04 '22 at 15:14
`pshell.AddParameter("Destination", textbox1.text);` you don't need the `$` — Charlieface, Jan 04 '22 at 15:19
You should accept the duplicate using the button I think you have — Charlieface, Jan 04 '22 at 22:56
