Asp.net reCaptcha-读取JSON响应

我从重新捕获中得到响应，需要读取“success”值，但得到错误：

Public member 'success' on type 'Dictionary(Of String,Object)' not found.

回应

{“成功”：正确，“挑战”：“2017-02-20T13:55:01Z”，“主机名”：“domain.co.uk”}

我正在尝试使用以下方式访问它：

data.success

data.success

完整代码

Dim Response As String = Request.Form("g-recaptcha-response")
Dim Valid As Boolean = False
Dim req As HttpWebRequest = DirectCast(WebRequest.Create(Convert.ToString("https://www.google.com/recaptcha/api/siteverify?secret=" & SecretKey & "&response=") & Response), HttpWebRequest)
Try
    Using wResponse As WebResponse = req.GetResponse()

        Using readStream As New StreamReader(wResponse.GetResponseStream())
            Dim jsonResponse As String = readStream.ReadToEnd()
            Dim js As New JavaScriptSerializer()
            Dim data As Object = js.Deserialize(Of Object)(jsonResponse)
            Valid = Convert.ToBoolean(data.success)
        End Using
    End Using

    Return Valid
Catch ex As WebException
    Throw ex
End Try

最终得到了答案，因此，如果这对任何人都有帮助，那么：

data("success")

而不是
