Properties

Properties allow you to control the accessibility of a classes variables, and is the recommended way to access variables from the outside in an object oriented programming language like C#.

A property is much like a combination of a variable and a method - it can't take any parameters, but you are able to process the value before it's assigned to our returned. A property consists of 2 parts, a get and a set method, wrapped inside the property: 

private string color;

public string Color

{

    get { return color; }

    set { color = value; }

}

Example:

class Program

    {

        public static void Main()

        {

            Car objcar = new Car();

            objcar.color = "Red";

            Console.WriteLine(objcar.describe());

            objcar.color = "Green";

            Console.WriteLine(objcar.describe());

            Console.ReadLine();

        }

    }

    class Car

    {

        private string colour;

       

        public string describe()

        {

            return "The colour of the Car is: " + color;

        }

        public string color

        {

            get { return colour; }

            set

            {

                if (value == "Green")

                {

                    colour = value.ToUpper();

                }

                else

                {

                    colour = value.ToLower();

                }

            }

        }

    }

Output:

The colour of the Car is: red

The colour of the Car is: GREEN
