如何检查/检测用户是否接受cookie？使用ASP.NET（C＃）

Answer 1

来自MSDN

确定是否接受cookie的一种方法是尝试编写cookie然后再尝试再读取它。如果您无法阅读您编写的cookie，则认为在浏览器中关闭了cookie。

写道：

Sub Page_Load()
   If Not Page.IsPostBack Then
      If Request.QueryString("AcceptsCookies") Is Nothing Then
           Response.Cookies("TestCookie").Value = "ok"
           Response.Cookies("TestCookie").Expires = _
              DateTime.Now.AddMinutes(1)
           Response.Redirect("TestForCookies.aspx?redirect=" & _
              Server.UrlEncode(Request.Url.ToString))
      Else
           labelAcceptsCookies.Text = "Accept cookies = " & _
              Request.QueryString("AcceptsCookies")
      End If
   End If
End Sub

然后阅读

Sub Page_Load()
    Dim redirect As String = Request.QueryString("redirect")
    Dim acceptsCookies As String
    ' Was the cookie accepted?
    If Request.Cookies("TestCookie") Is Nothing Then
        ' No cookie, so it must not have been accepted
        acceptsCookies = 0
    Else
        acceptsCookies = 1
        ' Delete test cookie
        Response.Cookies("TestCookie").Expires = _
           DateTime.Now.AddDays(-1)
    End If
    Response.Redirect(redirect & "?AcceptsCookies=" & acceptsCookies, _
       True)
End Sub

Answer 2

为Cookie保存一个值，重定向到某个页面并尝试重新读取该值。如果有效，则启用cookie。如果没有，那就没有。
