How to add a case-insensitive option to Array.IndexOf

I have a string

string str=\"hello\";

This is my array

string[] myarr = new string[] {\"good\",\"Hello\", \"this\" , \"new\         


        

Answer 1

Beaware !! The Answer marked might have some problem , like

string array[] = {"hello", "hi", "bye" , "welcome" , "hell"}

if you use the same method as described in the answer to find the index of word "hell"

Int Indexofary = Array.FindIndex(array, t => t.IndexOf("hell", StringComparison.InvariantCultureIgnoreCase) >=0);

you will get result Indexofary = 0 instead of 4.

Instead of that use

Array.FindIndex(array, t => t.Equals("hell", StringComparison.InvariantCultureIgnoreCase));

to get proper result .
