class MyArrayRankSample
    public static void Main()
            int[,,] myArray = new int[,,] {{{12,2,35},{300,78,33}},{{92,42,135},{30,7,3}}};
            Type myType = myArray.GetType();

            Console.WriteLine("Contents of myArray: {{{12,2,35},{300,78,33}},{{92,42,135},{30,7,3}}}");
            Console.WriteLine("myArray has {0} dimensions.", myType.GetArrayRank());
        catch(NotSupportedException e)
            Console.WriteLine("NotSupportedException raised.");
            Console.WriteLine("Source: " + e.Source);
            Console.WriteLine("Message: " + e.Message);
