        string str1 = "Pink Floyd";
        string str2 = "Ariana";
        Console.WriteLine("String 1 = " + str1);
        Console.WriteLine("String1 ToLowerInvariant = " + str1.ToLowerInvariant());
        Console.WriteLine("String 2 = " + str2);
        Console.WriteLine("String2 ToLowerInvariant = " + str2.ToLowerInvariant());
        Console.WriteLine("String 1 is equal to String 2: {0}", str1.Equals(str2));
