If this is something you need to do a lot in your application  or you need to chain different calls  you can create an extension method    public static String TrimEnd this String str  int count        return str Substring 0  str Length - count       and call it   string oldString       Hello    string newString   oldString Trim 1     returns     Hello    or chained   string newString   oldString Substring 3  Trim 1      returns  Hello

If you are using string datatype  below code works   string str   str Remove str Length - 1       But when you have StringBuilder  you have to specify second parameter length as well     That is    string newStr   sb Remove sb Length - 1  1  ToString         To avoid below error
