ASP.Net Cookie问题

Question

当用户插入时,我有一个cookie:

HttpCookie cookie = new HttpCookie("Username");
                    cookie.Expires = DateTime.Now.AddDays(1.0);
                    cookie.Value = txtUsername.Text;
                    Response.Cookies.Add(cookie);

当用户再次访问时,它会在登录页面中读出:

if (Response.Cookies["Username"] != null) txtUsername.Text = Response.Cookies["Username"].Value;

但是当我登录,然后我直接注销后,cookie就会被删除.它既没有exp-date也没有保存值.

Whot我错了吗？

Answer 1

if (Response.Cookies["Username"] != null) txtUsername.Text = Response.Cookies["Username"].Value

应该

if (Request.Cookies["Username"] != null) txtUsername.Text = Request.Cookies["Username"].Value
