A cookie wrapper class. Easily read, create, update and delete cookies in MVC

Create a new class with name CookieHelper.cs In your project and paste the following code.

public class CookieHelper
    {
        #region Constants

        /// <summary>
        /// The cookie name
        /// </summary>
        public const string cookieName = "UserName";

        #endregion

        #region Enums

        public enum EnumCookieInterval

How to use?

1. Create cookie 

string cookie = CookieHelper.CreateCookie(CookieHelper.cookieName, "Here is cookie value", CookieHelper.EnumCookieInterval.DAY, 7);

string cookie = CookieHelper.CreateCookie(CookieHelper.cookieName, "Here is cookie value", CookieHelper.EnumCookieInterval.MONTH, 1);

2. Read Cookie

string cookie = CookieHelper.ReadCookie(CookieHelper.cookieName);

3. Update Cookie

string newCookie = CookieHelper.UpdateCookie(CookieHelper.cookieName, "Updated cookie value", CookieHelper.EnumCookieInterval.DAY, 14);

4. Delete Cookie

CookieHelper.DeleteCookie(CookieHelper.cookieName);
