Chapter 10.2, Problem 10.9CP

Explanation of Solution

Assigning a value to a read-only property:

• Read-only property has a get method, but it does not have any set method to modify the value.
• In order to make a property read only, simply write a “set” accessor method for the property.
• Therefore, the property becomes a read-only property.
• When someone tries to assign a value to a read-only property, an error will occur at the time of executing the program.

Example:

//Include libraries

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text.RegularExpressions;

//Define namespace

namespace ConsoleApplication7

{

    //Define class

    public class Square

    {

        //Field

        private double _perimeter;

        //Define a constructor

        Square()

        {

            //Assign value

            _perimeter=0.0;

        }

        //Perimeter property

        public double Perimeter

        {

            //Input value

            set

            {

                _perimeter=value;

            }

            //Display value

            get

            {

                return _perimeter;

            }
