How to ignore the case sensitivity in List

Question

Let us say I have this code

string seachKeyword = \"\";
List sl = new List();
sl.Add(\"store\");
sl.Add(\"State\");
sl.Add(\"STAM         


        

Answer 1

One of possible (may not be the best), is you lowercase all of the strings put into sl. Then you lowercase the searchKeyword.

Another solution is writing another method that lowercase 2 string parameters and compares them
