//登录用户名
hcookie.Values["lastVist"] = DateTime.Now.ToString
(); //上次访问时间
hcookie.Values["nowVist"] = DateTime.Now.ToString
(); //本次访问时间
hcookie.Values["count"] = "1"; //登录用户访问
次数
hcookie.Expires = DateTime.Now.AddDays(30);
//设置保存时间是30天
Response.Cookies.Add(hcookie);
}
else
{
HttpCookie hcookie = new HttpCookie(loginName); hcookie.Values["username"] = this.txtName.Text; String lastVist = Request.Cookies[loginName]
["nowVist"];
hcookie.Values["lastVist"] = lastVist;
hcookie.Values["nowVist"] = DateTime.Now.ToString
();
hcookie.Values["count"] = (Convert.ToInt32
(Request.Cookies[loginName]["count"].ToString()) + 1).ToString
();
hcookie.Expires = DateTime.Now.AddDays(30); Response.Cookies.Add(hcookie);
} Response.Redirect("Welcome.aspx");
}
private String getName()

String uname = this.txtName.Text;
Session["uname"] = uname;
return uname;
}
