How to get current working directory inside a Cmdlet

Question

I am writing a Cmdlet for PowerShell in C#. I am subclassing a Cmdlet and NOT a PSCmdlet.

Is there a way to get the current directory from PowerShell? I could do so with the PSCmdlet using GetVariableValue("pwd"). But in the Cmd class I do not have that available.

Environment.CurrentDiretory points me to the path where powershell was started from, not where PowerShell itself is currently positioned.

edit

Example:

I fire up powershell via - say - powershell_ise.exe. It starts up in C:\Windows\System32\WindowsPowerShell\v1.0. I then change path using cd c:\my\folder and run my command Do-Something. Inside the implementation of "Do-Something" (C#-side) I'd like to be able to retrieve the current path => c:\my\folder.

If possible, I would like to avoid using PSCmdlet.

You should really be using PSCmdlet or pass the location as parameter argument from the invoking cmdlet. — Mathias R. Jessen

I am currently rewriting my code to derive from PSCmdlet. Looks good so far. I was a bit scared of it because I really don't need much of it, except access to it's internals. And on the other hand ... that's exactly what it's for I guess... — Hemisphera

Exactly, you have a runtime dependecy (current location) = use PSCmdlet — Mathias R. Jessen

I am starting in C:\Users\<myusername>. If I know enter cd.. I am in C:\Users\

Entering (Get-Location).Path returns C:\Users. Thats what you want, isnt it?

Altrnativly try:

WriteObject(this.SessionState.Path.CurrentFileSystemLocation);

I updated my original answer with an example. I would like to avoid running further cmdlets to get my current path. Unless I have no other way.

@Hemisphera I've updated my answer. I don't have access to LinqPad or Visual Studio right now, so I can't confirm this works,

It only works because I now use PSCmdlet. Cmdlet alone does not provide access to SessionState. But since I ended up using PSCmdlet I'll mark this as answered. It's cleaner than GetVariableValue("pwd") anway. Thanks!
