Substring a string from the end of the string

Question

I need to remove two characters from the end of the string.

So:

string = \"Hello Marco !\"

must be

Hello Marco
         


        

Answer 1

I will trim the end for unwanted characters:

s = s.TrimEnd(' ', '!');

To ensure it works even with more spaces. Or better if you want to ensure it works always, since the input text seems to come from the user:

Regex r = new Regex(@"(?'purged'(\w|\s)+\w)");
Match m = r.Match("Hello Marco   !!");
if (m.Success)
{
    string result = m.Groups["purged"].Value;
}

With this you are safer. A purge based on the fact the last two characters has to be removed is too weak.
