人亦已歌

使用实例：

private User u = new User();
private string urlPath = 
protected void Page_Load(object sender, EventArgs e)
    if (!Page.IsPostBack)
    {
    #region 基础数据
    u = new User();
    u.UserName = "慈众营销"; 
    u.UserAge = 27; 
    u.UserSex = "男"; 
    u.UserSite = "http://www.zhengdecai.com"; 
    urlPath = Server.MapPath("~/file/"); 
    #endregion
    cookieInfo();
    }
///<summary>
/// Cookie测试
///</summary>
private void cookieInfo()
    CookieHelper.SetCookie("userName", "慈众营销");
    CookieHelper.SetCookie("userAge", "27", DateTime.Now.AddDays(1));
    CookieHelper.WriteCookie("userSex", "男");
    CookieHelper.WriteCookie("userSite", "http://www.zhengdecai.com", 20);
    //CookieHelper.SetCookie("u", u);
    CookieHelper.ClearCookie("userName");
    CookieHelper.RemoveCookie("userAge");
    string cStr = CookieHelper.GetCookieValue("userName") + " - " + CookieHelper.GetCookieValue("userAge") + " - " + CookieHelper.GetCookieValue("userSex") + " - " + CookieHelper.GetCookieValue("userSite");
    Response.Write("存在Cookie：" + cStr + "<br/>");
    CookieHelper.ClearCookie("userName");
    cStr = CookieHelper.GetCookieValue("userName") + " - " + CookieHelper.GetCookieValue("userAge") + " - " + CookieHelper.GetCookieValue("userSex") + " - " + CookieHelper.GetCookieValue("userSite");
    CookieHelper.ClearAllCookie();
