从vb.net中的httpwebrequest获取Json响应

我正在处理一个旧的VB.NET（ASP.NET）网页，我需要获得HttpWebRequest调用的响应，如下所示：

Dim s As HttpWebRequest
Dim enc As UTF8Encoding
Dim postdatabytes As Byte()
s = httpWebRequest.Create("www.theurl.com/api")
enc = New System.Text.UTF8Encoding()
Dim PostData = "grant_type=client_credentials"
postdata = postdata & "&client_id=" & ConfigurationManager.AppSettings("client_id")
postdata = postdata & "&client_secret=" & ConfigurationManager.AppSettings("client_secret")
postdata = postdata & "&audience=" & ConfigurationManager.AppSettings("audience")
postdatabytes = enc.GetBytes(postdata)
s.Method = "POST"
s.ContentType = "application/x-www-form-urlencoded"
s.ContentLength = postdatabytes.Length

Using stream = s.GetRequestStream()
      stream.Write(postdatabytes, 0, postdatabytes.Length)
End Using
Dim result = s.GetResponse()
response.write(result)

我遇到的问题是，我在写“result”时得到的不是Postman提供的Json字符串，而是响应：

有什么想法吗

谢谢

对于那些寻找答案的人，我通过添加以下代码使其工作：

Dim responsedata As Stream = result.GetResponseStream
Dim responsereader As StreamReader = New StreamReader(responsedata)
Dim xResponse = responsereader.ReadToEnd
Response.Write(xResponse)

谢谢

Dim responsedata As Stream = result.GetResponseStream
Dim responsereader As StreamReader = New StreamReader(responsedata)
Dim xResponse = responsereader.ReadToEnd
Response.Write(xResponse)
