Category: Introduction, viewed: 1164 time(s).
In this example we create a property. Property is used to read or write fields or attributes of a class. In our User class web have four fields id, username, firstName, lastName. Next we create properties for setting and getting the value of the property.
using System;
namespace Kodecsharp.Example.Intro
{
public class User
{
private long id;
private string username;
private string firstName;
private string lastName;
public User()
{
}
/// <summary>
/// User ID Property
/// </summary>
public long Id
{
get
{
return id;
}
set
{
id = value;
}
}
/// <summary>
/// Username Property
/// </summary>
public string Username
{
get
{
return username;
}
set
{
username = value;
}
}
/// <summary>
/// Firstname Property
/// </summary>
public string FirstName
{
get
{
return firstName;
}
set
{
firstName = value;
}
}
/// <summary>
/// Lastname Property
/// </summary>
public string LastName
{
get
{
return lastName;
}
set
{
lastName = value;
}
}
public static void Main(string[] args)
{
User user = new User();
user.Id = 1;
user.Username = "admin";
user.FirstName = "System";
user.LastName = "Administrator";
System.Console.WriteLine("User: " + user.Id + "; " +
user.Username + "; " + user.FirstName + "; " +
user.LastName);
}
}
}
