一个简单的用Cookie记住用户名密码的例子

Button事件里

protected void Button1_Click(object sender, EventArgs e)    {        Request.Cookies.Clear();        HttpCookie myname = new HttpCookie("nameinfo");        myname["name"] = TextBox1.Text;        myname["pass"] = TextBox2.Text;        myname.Expires = DateTime.Now.AddHours(1);        Response.Cookies.Add(myname);    }

初始化加载的时候

protected void Page_Load(object sender, EventArgs e)    {        if (Request.Cookies["nameinfo"] != null)        {            TextBox1.Text = Request.Cookies["nameinfo"]["name"].ToString();            TextBox2.Attributes["value"] = Request.Cookies["nameinfo"]["pass"].ToString();//如果直接给TextMode="Password"的TextBox2赋值，将不能显示在TextBox2        }    }
