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

You can apply little trick over this.
Change all the string to same case: either upper or lower case

List searchResults = sl.FindAll(s => s.ToUpper().Contains(seachKeyword.ToUpper()));
