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

Use Linq, this adds a new method to .Compare

using System.Linq;
using System.Collections.Generic;

List MyList = new List();
MyList.Add(...)
if (MyList.Contains(TestString, StringComparer.CurrentCultureIgnoreCase)) {
    //found
} 

so presumably

using System.Linq;
...

List searchResults = sl.FindAll(s => s.Contains(seachKeyword, StringComparer.CurrentCultureIgnoreCase));
