1、增加Cookie的写入方法：

/// <summary>

        /// 写 Cookies

        /// </summary>

        /// <param name="cookieName">主键</param>

        /// <param name="cookieValue">键值</param>

        /// <param name="hours">有效时间（小时）</param>

        /// <returns></returns>

        public static bool SetCookie(string cookieName, string cookieValue, int hours)

        {

            try

            {

                HttpCookie Cookie = new HttpCookie(cookieName);

                if (!string.IsNullOrEmpty(Settings.Domain))

                    Cookie.Domain = Settings.Domain;

                Cookie.Expires = DateTime.Now.AddHours(hours);

                Cookie.Value = SecurityHelper.Encrypt(cookieValue);

                System.Web.HttpContext.Current.Response.Cookies.Add(Cookie);

                return true;

            }

            catch

            {

                return false;

            }

        }

2、增加Cookie的读取方法：

 /// <summary>

        /// 读取Cookies

        /// </summary>

        /// <param name="CookieName">主键</param>

        /// <returns></returns>

        public static string GetCookie(string CookieName)

        {

            HttpCookie Cookie = System.Web.HttpContext.Current.Request.Cookies[CookieName];

            if (Cookie != null)

            {

                return SecurityHelper.Decrypt(Cookie.Value.ToString());

            }

            else

            {

                return null;

            }

        }

3、增加对Cookie的删除方法：

/// <summary>

        /// 删除Cookies

        /// </summary>

        /// <param name="cookieName">主键</param>

        /// <returns></returns>

        public static bool DeleteCookie(string cookieName)

        {

            try

            {

                HttpCookie Cookie = new HttpCookie(cookieName);

                if (!string.IsNullOrEmpty(Settings.Domain))

                {

                    Cookie.Domain = Settings.Domain;

                }

                Cookie.Expires = DateTime.Now.AddDays(-1);

                System.Web.HttpContext.Current.Response.Cookies.Add(Cookie);

                return true;

            }

            catch

            {

                return false;

            }

        }

4、增加Cookie的过期时间设置：

/// <summary>

        /// 更新cookie过期时间

        /// </summary>

        /// <param name="cookieName"></param>

        /// <param name="cookieValue"></param>

        /// <param name="minutes"></param>

        public static void ModCookies(string cookieName, string cookieValue, int minutes)

        {

            var httpCookie = HttpContext.Current.Response.Cookies[cookieName];

            if (httpCookie != null)

            {

                httpCookie.Value = cookieValue;

                httpCookie.Expires = DateTime.Now.AddMinutes(minutes);

            }

        }
