Label1.Text = (Session["userInfo"] as UserInfo).UserName + "欢迎您！";
 if (Request.Cookies["name"] == null)
 {
 HttpCookie hc = new HttpCookie("name", (Session["userInfo"] as UserInfo).UserName);
 hc.Expires = DateTime.Now.AddMonths(1);
 HttpCookie tm = new HttpCookie("time", DateTime.Now.ToString());
 tm.Expires = DateTime.Now.AddMonths(1);
 HttpCookie ct = new HttpCookie("count", "1");
 ct.Expires = DateTime.Now.AddMonths(1);
hc.Domain="xxx.com";//域名
tm.Domain="xxx.com";//域名
ct.Domain="xxx.com";//域名
 Response.Cookies.Add(hc);
 Response.Cookies.Add(ct);
 Response.Cookies.Add(tm);
 }

 {
 Response.Cookies["time"].Value = DateTime.Now.ToString();
 Response.Cookies["count"].Value = (int.Parse(Request.Cookies["count"].Value) + 1).ToString();
