我有以下使用 RestSharp 调用 Web 服务的代码。代码运行没有错误，但是当我查看 response.Data 时，我看到 Result 对象没有反序列化，并且仍然包含默认值。
<Serializable()> <DataContract()> _
Private Class Result
<DataMember(IsRequired:=False)> _
Public responseCode As Long
<DataMember(IsRequired:=False)> _
Public responseMessage As String
Friend Const RESULT_OK As Long = 2000
End Class
Private Function Login(ByVal user As String, ByVal password As String) As RestResponseCookie
Dim req As New RestRequest("authenticationService/authentication/signIn", Method.POST)
req.RequestFormat = DataFormat.Json
Dim input As New SigninInput
input.requestParameters.username = user
input.requestParameters.password = password
req.AddBody(input)
Dim response As RestResponse(Of Result) = getRestClient().Execute(Of Result)(req)
If response.StatusCode = HttpStatusCode.OK Then
Dim res As Result = response.Data
End If
Return Nothing
End Function
现在，如果我将代码更改为以下内容：
Dim response As RestResponse = getRestClient().Execute(req)
If response.StatusCode = HttpStatusCode.OK Then
Dim des As New Json.DataContractJsonSerializer(GetType(Result))
Dim res As Result = CType(des.ReadObject(New IO.MemoryStream(response.RawBytes)), Result)
End If
反序列化运行得很好。我尝试从代码的非工作版本中调试结果，并且内容似乎很好。这是我得到的内容： "{"responseMessage":"Success: Your request was successfully completed.","responseCode":2000}" 并且 ContentType 应该是“application/json”。
我可以运行有效的代码，但我很高兴知道为什么 RestSharp 的反序列化没有正确进行。
