Add a trailing # to each string of a list results in #//

Question

I would like to add a trailing # to every string of a list of strings. The # is added, but as well two \. What can I do to correct this piece of code?

Input:

Houseplant

Algorithm:

tmpList = tmpList.Select(hashtag => Path.Combine("#", hashtag)).ToList();

Output:

#\\Houseplant

Answer 1

If you don't mean to concatenate these as paths (with a / separating them) then dont use Path.Combine.

You could just use String.Concat:

tmpList = tmpList.Select(hashtag => String.Concat("#", hashtag)).ToList();
