1、增加Cookie的写入方法:

  1. /// <summary>
  2. /// 写 Cookies
  3. /// </summary>
  4. /// <param name="cookieName">主键</param>
  5. /// <param name="cookieValue">键值</param>
  6. /// <param name="hours">有效时间（小时）</param>
  7. /// <returns></returns>
  8. public static bool SetCookie(string cookieName, string cookieValue, int hours)
  9. {
  10.     try
  11.     {
  12.         HttpCookie Cookie = new HttpCookie(cookieName);
  13.         if (!string.IsNullOrEmpty(Settings.Domain))
  14.             Cookie.Domain = Settings.Domain;
  15.         Cookie.Expires = DateTime.Now.AddHours(hours);
  16.         Cookie.Value = SecurityHelper.Encrypt(cookieValue);
  17.         System.Web.HttpContext.Current.Response.Cookies.Add(Cookie);
  18.         return true;
  19.     }
  20.     catch
  21.     {
  22.         return false;
  23.     }
  24. }

2、增加Cookie的读取方法：

  1. /// <summary>
  2. /// 读取Cookies
  3. /// </summary>
  4. /// <param name="CookieName">主键</param>
  5. /// <returns></returns>
  6. public static string GetCookie(string CookieName)
  7. {
  8.     HttpCookie Cookie = System.Web.HttpContext.Current.Request.Cookies[CookieName];
  9.     if (Cookie != null)
  10.     {
  11.         return SecurityHelper.Decrypt(Cookie.Value.ToString());
  12.     }
  13.     else
  14.     {
  15.         return null;
  16.     }
  17. }

3、增加对Cookie的删除方法：

  1. /// <summary>
  2. /// 删除Cookies
  3. /// </summary>
  4. /// <param name="cookieName">主键</param>
  5. /// <returns></returns>
  6. public static bool DeleteCookie(string cookieName)
  7. {
  8.     try
  9.     {
  10.         HttpCookie Cookie = new HttpCookie(cookieName);
  11.         if (!string.IsNullOrEmpty(Settings.Domain))
  12.         {
  13.             Cookie.Domain = Settings.Domain;
  14.         }
  15.         Cookie.Expires = DateTime.Now.AddDays(-1);
  16.         System.Web.HttpContext.Current.Response.Cookies.Add(Cookie);
  17.         return true;
  18.     }
  19.     catch
  20.     {
  21.         return false;
  22.     }
  23. }

4、增加Cookie的过期时间设置：

  1. /// <summary>
  2. /// 更新cookie过期时间
  3. /// </summary
  4. /// <param name="cookieName"></param>
  5. /// <param name="cookieValue"></param>
  6. /// <param name="minutes"></param>
  7. public static void ModCookies(string cookieName, string cookieValue, int minutes)
  8. {
  9.     var httpCookie = HttpContext.Current.Response.Cookies[cookieName];
  10.     if (httpCookie != null)
  11.     {
  12.         httpCookie.Value = cookieValue;
  13.         httpCookie.Expires = DateTime.Now.AddMinutes(minutes);
  14.     }
  15. }
