Is there a way to make the following return true?

 string title = "ASTRINGTOTEST";
 title.Contains("string");

There doesn't seem to be an overload that allows me to set the case sensitivity.. 
Currently I UPPERCASE them both, but that's just silly.

**UPDATE** 
The sillyness I refer to is the [i18n][1] issues that come with up- and down casing.
