if(!IsPostBack) { UserInfo userInfo = Session["userInfo"] as UserInfo; if (userInfo == null) { Response.Redirect("Login.aspx"); } else if (userInfo.UserName != "王浡" && userInfo.PassWord != "wangbo") { Response.Redirect("Login.aspx"); } else { HttpCookie cookie; int count = 1; string time = ""; if (Request.Cookies["Test"] == null) { cookie = new HttpCookie("Test"); } else { cookie = Request.Cookies["Test"]; count = int.Parse(cookie.Values["count"]); count++; time = cookie.Values["time"]; } cookie.Values["count"] = count.ToString(); cookie.Expires = DateTime.Now.AddDays(1); cookie.Values["time"] = DateTime.Now.ToString(); Response.Cookies.Add(cookie); lblMessage.Text = userInfo.UserName + "欢迎您！！！"; Response.Write("上次登录时间为："+time+"<br>"); Response.Write("登录次数为：" + count + "<br>"); }
