Trim last character from a string

Question

I have a string say

\"Hello! world!\" 

I want to do a trim or a remove to take out the ! off world but not off Hello.

Answer 1

if (yourString.Length > 1)
    withoutLast = yourString.Substring(0, yourString.Length - 1);

or

if (yourString.Length > 1)
    withoutLast = yourString.TrimEnd().Substring(0, yourString.Length - 1);

...in case you want to remove a non-whitespace character from the end.
