LINQPad script directory?

Question

Does anyone know how to get hold of the path to the directory where the LINQPad script file (.linq) resides?

Or to the script itself for that matter.

Note that I'm not talking about the location of the "My Queries" folder, the one shown inside LINQPad.

I can save a .linq file anywhere on disk, and open it by double-clicking on it.

For instance, if I save the file to C:\Temp\Test.linq, and execute the program, I'd like to have either C:\Temp or C:\Temp\Test.linq.

Basically I'd like something akin to Environment.CurrentDirectory or Assembly.GetEntryAssembly().Location, just for the .linq file.

Things I've tried:

Looking through environment variables
Looking through the LINQPad assembly that is given to my script
Throwing an exception and looking at the stacktrace (contains a link to a temporary copy of my script somewhere else)
Environment.CommandLine.Dump(); - gives LINQPad executable
Environment.CurrentDirectory.Dump(); - gives C:\windows\system32
Assembly.GetExecutingAssembly().Location.Dump(); - gives temp directory

The execution context is always going to be the program location. You need a specific LinqPAD API if one exists for the file location. — cjk, Sep 27 '10 at 10:45
Yes, I was kinda wondering if someone know what that was :) (assuming there is one) — Lasse V. Karlsen, Sep 27 '10 at 12:32

I've just added a feature to address this. You can test it now by downloading the 2.27.1 or 4.27.1 beta build.

To get the current query's folder, use the following expression:

Path.GetDirectoryName (Util.CurrentQueryPath)

There are many reasons why I just love LINQPad, and you seem to have no problem coming up with new reasons :) Thank you so much! – Lasse V. Karlsen Sep 28 '10 at 10:17

How is it I only just found the `Util` type?! – user9993 Jul 17 '17 at 09:40
Linqpad v5.x `Util.CurrentQueryPath ` returns null. – lucuma Jan 25 '19 at 14:13

Have you saved your query? (If not, there will be no query path) – Joe Albahari Feb 02 '19 at 03:30

I presume you mean programatically and not through the UI itself.

The path to the linq file directory is held in

%APPDATA%\LINQPad\querypath.txt

No, that contains the path to the "My Queries" directory. I can easily save .linq files everywhere else, and it's the real location I want, I'll edit the question to clarify. I want the full path to the .linq file of the currently executing script. – Lasse V. Karlsen Sep 27 '10 at 10:30
Ah ok - the question is clearer now. I don't know the answer but what would you like returned when you execute a query that hasn't yet been saved? – kjn Sep 27 '10 at 10:35
Anything basically, temp, whatever. It would probably in that case be logical that it returned the path to a temporary copy of the script. For instance, for some reason I might be interested in reading the source, but my primary use is to access data files in the same directory as the script itself, without hardcoding the path to where the script lives. – Lasse V. Karlsen Sep 27 '10 at 10:38
I've posted the question on the forum of the LINQPad authors book, so I'll see if that can give me the specifics, or perhaps a feature request :) – Lasse V. Karlsen Sep 27 '10 at 12:33

The next question after "How do I get LinqPad script directory" is "How do I set it?" below is how you do it and link to where I found the answer

Directory.SetCurrentDirectory (Path.GetDirectoryName (Util.CurrentQueryPath));

That changes the "current directory" of the process, it does not change the LINQPad script directory location. – Lasse V. Karlsen Apr 09 '22 at 13:47
Good to know. Thanks for the clarification. – Geovani Martinez Apr 20 '22 at 16:22
