请教读取cookie的问题

[dabuyingyeyaoda]

代码如下

    Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim cook As HttpCookie = New HttpCookie("UserInfo")
        cook.Expires = Now.AddDays(2)
        cook.Value = "XXX"

        HttpContext.Current.Response.Cookies.Add(cook)


        'Me.Response.AppendCookie(cook)

    End Sub

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim cookRead As HttpCookie = HttpContext.Current.Response.Cookies("UserInfo")
        TextBox1.Text = cookRead.Values.Count

    End Sub

HttpContext.Current.Response.Cookies("UserInfo") 读取出来的value为空，请教为何？

是不是要这么写 HttpContext.Current.Request.Cookies("UserInfo")

[dalmeeme]

改为：Dim cookRead As HttpCookie = HttpContext.Current.Request.Cookies("UserInfo")

正确。 很容易理解，Cookie是放在客户端的，所以应该是Request（客户端来的“请求”），而不是Response（服务器发过去的“响应”）。
