1、写cookie方法

    #region 登录时写入cookie
    public static void LoginCookieSave(string uid, string loginname, string pwd)
    {
        System.Web.HttpCookie logincookie = new System.Web.HttpCookie("userinfo");
        logincookie.Values.Add("uid", uid);
        logincookie.Values.Add("loginname", ICore.IChecking.Escape(loginname));
        logincookie.Values.Add("pwd", pwd);
        logincookie.Expires = DateTime.Now.AddMonths(12);
        logincookie.Domain = "domain.com";
        HttpContext.Current.Response.AppendCookie(logincookie);
    }
    #endregion

2、读取cookie方法

    /// <summary>
    /// 获得Cookie的值
    /// </summary>
    /// <param name="cookieName"></param>
    /// <param name="key"></param>
    /// <returns></returns>
    public static string GetCookieValue(string cookieName, string key)
    {
        HttpRequest request = HttpContext.Current.Request;
        if (request != null)
            return GetCookieValue(request.Cookies[cookieName], key);
        return "";
    }


    /// <summary>
    /// 获得Cookie的子键值
    /// </summary>
    /// <param name="cookie"></param>
    /// <param name="key"></param>
    /// <returns></returns>
    public static string GetCookieValue(HttpCookie cookie, string key)
    {
        if (cookie != null)
        {
            if (!string.IsNullOrEmpty(key) && cookie.HasKeys)
                return cookie.Values[key];
            else
                return cookie.Value;
        }
        return "";
    }
