#772 – Initializing an Array as Part of a Method Call

When you want to pass an array to a method, you could first declare the array and then pass the array by name to the method.

Suppose that you have a Dog method that looks like this:

        public void DoBarks(string[] barkSounds)
        {
            foreach (string s in barkSounds)
                Console.WriteLine(s);
        }

You can declare the array and pass it to the method:

            Dog d = new Dog();

            // Declare array and then pass
            string[] set1 = { "Woof", "Rowf" };
            d.DoBarks(set1);

Or you can just initialize a new array instance as part of the method call, without first declaring it:

            // Initialize and pass array without declaring
            d.DoBarks(new string[] { "Grr", "Ack-ack" });

You can also initialize a multi-dimensional array as part of a method call:

            // Initialize and pass multi-dimensional array
            d.AddNumbers(new int[,] { { 1, 2, 3 }, { 9, 10, 11 }, { 100, 12, 32 } });
