C# properties

Properties are the members of a class, interface, and structure in C#. As we know that, members or methods of class and structure are known as "Fields". Properties are an extended version of fields with almost same syntax.

Using properties, we can read and write or manipulate private fields. For example, we have a class name EMPLOYEE that contains private fields EMP_ID, EMP_NAME, EMP_SALARY. Normally we cannot access those fields out of the class. But using Properties we can access them.

Types of C# properties

There are two types of properties are using to access private fields:

1. set - To write value in private fields
2. get - To read value of private fields

Declaration:

public int ID
{
	get
	{
		return EMP_ID;
	}

	set 
	{
		EMP_ID = value;
	}
}

public string NAME
{
	get
	{
		return EMP_NAME;
	}

	set 
	{
		EMP_NAME = value;
	}
}

public int SALARY
{
	get
	{
		return EMP_SALARY;
	}
	set 
	{
		EMP_SALARY = value;
	}
}

Example: With the help of program, we can understand about properties easily...

using System;
using System.Collections;
namespace ConsoleApplication1
{
    class EMPLOYEE
    {
        private int     EMP_ID      ;
        private string  EMP_NAME    ;
        private int     EMP_SALARY  ;

        public int ID
        {
            get
            {
                return EMP_ID;
            }

            set
            {
                EMP_ID = value;
            }
        }

        public string NAME
        {
            get
            {
                return EMP_NAME;
            }

            set
            {
                EMP_NAME = value;
            }
        }

        public int SALARY
        {
            get
            {
                return EMP_SALARY;
            }
            set
            {
                EMP_SALARY = value;
            }
        }

    }

    
         
    class Program
    {
        static void Main()
        {
            EMPLOYEE E = new EMPLOYEE();

            E.ID   = 101;
            E.NAME = "Duggu Pandit";
            E.SALARY = 1000000;

            Console.WriteLine("ID     : " + E.ID);
            Console.WriteLine("NAME   : " + E.NAME);
            Console.WriteLine("SALARY : " + E.SALARY);

        }
    }
}

Output

    ID		: 101
    NAME	: Duggu Pandit
    SALARY	: 1000000
