I have this string
%1111_Ç2222_Ç3333_
and I want remove the characters between the first and second _
Ç2222_
What is the best way to do this?
Thanks


maybe you want to go into this direction, but your question is not that clear...
string sIn = "%1111_Ç2222_Ç3333_";
string sOut = string.Join("_", sIn.Split('_').Where((x, index) => index != 1));
