Is there a way to get if the string has a substring without maintaining the uppercase/lowercase in C#?

Question

For example, I have a string "ZONE123". Is there a way to get 'true' value when comparing it to substring "zone" - some kind of '.Contains("zone")'?

You can use IndexOf function:

   string s = "ZONE123";
   s.IndexOf("ZONE", StringComparison.InvariantCultureIgnoreCase) >= 0
