如何从对象中获得jsession值？

Question

以下是我的代码

Dim response As HttpWebResponse = TryCast(requset.GetResponse(), HttpWebResponse)
        dataStream = response.GetResponseStream()
        Dim reader As New StreamReader(dataStream)
        Dim responseFromServer As String = reader.ReadToEnd()

responseFromServer的结果是

  

{＆＃34;导致＆＃34;：0，＆＃34; jsession＆＃34;：＆＃34; f0fcb39d-8cf5-47a3-BA85-f3cedbd26561＆＃34;}

如何从responseFromServer获取Jsession？
