protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.GetLeft.Value = invited.GetInviteCountByWeb().ToString();
HttpCookie oldCookie = Request.Cookies["Time"];
if (oldCookie != null)
{
if (DateTime.Now.ToString("yyyy-MM-dd") == Convert.ToDateTime(oldCookie.Values["GetTime"]).ToString("yyyy-MM-dd"))
{
this.IsGet.Value = "false";
}
else
{
HttpCookie newCookie = new HttpCookie("Time");
newCookie.Values.Add("GetTime", DateTime.Now.Date.ToString("yyyy-MM-dd"));
newCookie.Expires = DateTime.Now.AddHours(24.0);
Response.Cookies.Add(newCookie);
}
}
}
}
但它不起作用,每次浏览器关闭时,oldcookie为null。 那么如何每天设置一次按钮?
答案 0 :(得分:3)
你的其他陈述在错误的地方,试试这样;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.GetLeft.Value = invited.GetInviteCountByWeb().ToString();
HttpCookie oldCookie = Request.Cookies["Time"];
if (oldCookie != null)
{
if (DateTime.Now.ToString("yyyy-MM-dd") == Convert.ToDateTime(oldCookie.Values["GetTime"]).ToString("yyyy-MM-dd"))
{
this.IsGet.Value = "false";
}
}
else
{
HttpCookie newCookie = new HttpCookie("Time");
newCookie.Values.Add("GetTime", DateTime.Now.Date.ToString("yyyy-MM-dd"));
newCookie.Expires = DateTime.Now.AddHours(24.0);
Response.Cookies.Add(newCookie);
}
}
