#802 – A Method Might Have No Parameters

You can pass one or more data values to a method using parameters.  A parameter in a method is just a variable, usable only within that method, that refers to a piece of data passed into the method.

If the method that you are writing requires no data to be passed in, you can omit all parameters.  You include an empty pair of parentheses after the method name, to indicate that the method has no parameters.

    public class Dog
    {
        public string Name { get; set; }
        public int Age { get; set; }

        // All data that we need is passed into constructor
        public Dog(string name, int age)
        {
            Name = name;
            Age = age;
        }

        // Bark is a method that has no parameters
        public void Bark()
        {
            Console.WriteLine(string.Format("{0} : WOOF !", Name));
        }
    }
