Remove Spaces From String Array


Some folder names are listed in an array like this: "Folder Name"

I want the result to be: "foldername"

This code below does not work. Any ideas?

                string folder = folderName[i].ToLower();
                folder.Replace(" ", string.Empty);

Open in new window

are you opposed to regex?
Regex.Replace(folder , @"\s+", "")

I'd guess that is a personal choice, based perhaps on readability & maintainabilty.

Most people (even non-programmers) can probably immediately see what is meant by

folder.Replace(" ", string.Empty)

but this is almost certainly not the case for:

Regex.Replace(folder , @"\s+", "")
that's why we are supposed to comment our code.
regex isn't always the best answer but it is flexible.
