Path.Combine() does not add directory separator after drive letter

Question

Am I using the Path.Combine Method Incorrectly?
I Get This Result With Path.Combine(string[]):

C:Users\\\\Admin\\\\AppData\\\\R         


        

Answer 1

It's in the documentation:

If path1 is not a drive reference (that is, "C:" or "D:") and does not end with a valid separator character [..], DirectorySeparatorChar is appended to path1 before concatenation.

So your first path, which is the drive letter, does not get a directory separator appended. You can for example fix this after splitting, by appending the separator to TempSave[0], but that'll cause issues with Linux like you said.

You can also solve your actual problem differently, see How do I find the parent directory in C#?, or just append ..\..\ like @Dan suggests so you can skip the splitting:

string desiredPath = Path.Combine(Application.UserAppDataPath, @"..\..\");
