property class in c#

Property is a name of data fields which are use to get and set the values. It is a member of class, Structs, and interfaces.

get{} :  getter are use to return a value.

set{} :  setter are use to get a value.

public int UserId { get; set; }

Example : get and set the values, In this step 1, we create property in a class

using System; 

using System.Collections.Generic; 

using System.Linq;  using System.Text;   

namespace PropertyExample 

{          

 public class UserDetails          

 {                       

   public int UserId { get; set; }                           

   public string UserName { get; set; }              

   public long PhoneNo { get; set; }   

 } 

}

In this step 2, we set the values which you want

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace PropertyExample

{

            public  class SetValues

            {

                        UserDetails _objUser=new UserDetails();

                        public UserDetails SetVal()

                        {

                                    _objUser.UserId = 001;

                                    _objUser.UserName = "Anil";

                                    _objUser.PhoneNo = 9090909090;

                                    return _objUser;

                        }

            }

}

In this step 3, we call the property and get the values which you set the above class

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace PropertyExample

{

            class Program

            {

                        static void Main(string[] args)

                        {

                                    SetValues objSetVal = new SetValues();

                                    UserDetails objUserDet = new UserDetails();

                                    objUserDet=objSetVal.SetVal();

                                    int id = objUserDet.UserId;

                                    string userName = objUserDet.UserName;

                                    long phone = objUserDet.PhoneNo;

                        }

            }

}

Property Explanation

1. When we are using get modifier that is called a read-only property.
2. When we are using set modifier that is called a write-only property.
3. When we are using both get and set modifiers that is called a read-write property.
4. Both get and set modifiers must be declared within the body of the property.
5. We cannot assign values in read-only property.
6. Properties are use to get and set the values using conditional statement.
