关于Cookie

1、 创建cookie
    

/// <summary>
        /// 创建cookie
        /// </summary>
        /// <param name="key">键</param>
        /// <param name="value">值</param>
        public static void CreateCookie(string childCookie, string value)
        {
            if (HttpContext.Current.Request.Cookies["LoanAssess"] != null && HttpContext.Current.Request.Cookies["LoanAssess"].Value != "")
            {
                HttpCookie cookies = HttpContext.Current.Request.Cookies["LoanAssess"];
                cookies.Values[childCookie] = value;
                cookies.Expires = DateTime.Now.AddDays(1);
                HttpContext.Current.Response.AppendCookie(cookies);
            }
            else
            {
                HttpCookie newcookie = new HttpCookie("LoanAssess");
                newcookie.Values[childCookie] = value;
                newcookie.Expires = DateTime.Now.AddDays(1);
                HttpContext.Current.Response.AppendCookie(newcookie);
            }
        }

 2、得到cookie值
        

/// <summary>
        /// 得到cookie值
        /// </summary>
        /// <param name="childKey">子键cookie</param>
        /// <returns></returns>
        public static string GetCookieValue(string childKey)
        {
            string cookieValue = "";
            HttpCookie cookies = HttpContext.Current.Request.Cookies["LoanAssess"];
            if (cookies != null && cookies.Values[childKey] != null)
            {
                cookieValue = cookies.Values[childKey];
            }
            return HttpUtility.UrlDecode(cookieValue);
        }
