By explicitly specifying it:

int c = string.Compare(a, b, StringComparison.InvariantCultureIgnoreCase)

You should use OrdinalIgnoreCase or CurrentCultureIgnoreCase depending on your needs. You normally don't want to use the InvariantCultures for comparisons - see msdn.microsoft.com/en-us/library/ms973919

@Manfred Thanks I was thinking about String.Equals(stringA, stringB, StringComparison.CurrentCultureIgnoreCase)

int c = string.Compare(a, b,true);

the last argument should be true (ignoreCase)

convert them to lower case then compare, There you go:

        string b = "b";
        string a = "";
        int c = string.Compare(a.ToLower(), b.ToLower());
