Question

Is there a nice way to extract part of a string with linq, example:
I have

string  s = "System.Collections.*";

or

string s2 = "System.Collections.Somethingelse.*";

my goal is to extract anything in the string without the last ‘.*‘

thankx I am using C#

Answer 1

The simplest way might be to use String.LastIndexOf followed by String.Substring

int index = s.LastIndexOf('.');

string output = s.Substring(0, index);

Unless you have a specific requirement to use LINQ for learning purposes of course.
