WCF 客户端返回“无”作为对第三方网络服务的响应

我有一个第三方 Web 服务（恰好是 peoplesoft EIP 服务），我试图从 .net 调用它。我尝试使用服务引用和旧的 Web 引用来调用此服务，每次调用它时，我都会从服务中得到“无”响应。

我已经通过 SoapUI 运行了服务调用，并且工作正常。我已经使用 Fiddler 捕获了网络流量，并注意到当我从 SoapUi 或 .Net 调用该服务时，我从调用中得到了相同的结果 xml。这意味着通话正常。我已在 WCF 中打开跟踪和日志记录，但没有看到任何错误。它也没有抛出异常。

所以我的理论是，.net 很难将服务中的 xml 转换回 .net 对象。

这是我的代码片段：

Dim psclient As New psService.LSS_WEBORDER_PortTypeClient

Dim psreq As New psService.LSS_WEBORDER_REQ_MSG_TypeShape
psreq = New psService.LSS_WEBORDER_REQ_MSG_TypeShape

Dim orderinfo(1) As psService.Transaction_TypeShape

Dim captureid As String = "WB" & Right(Guid.NewGuid.ToString, 8)
orderinfo(0) = New psService.Transaction_TypeShape
orderinfo(0).LSS_WEBOHDR_WRK = New psService.LSS_WEBOHDR_WRKMsgDataRecord_TypeShape
orderinfo(0).LSS_WEBOHDR_WRK.CAPTURE_ID = New psService.CAPTURE_ID_TypeShape
orderinfo(0).LSS_WEBOHDR_WRK.CAPTURE_ID.Value = captureid

psreq.MsgData() = orderinfo

Dim response As New psService.LSS_WEBORDER_RESP_MSG_TypeShape
response = psclient.LSS_WEBORDER_OP(psreq)
response.ToString() <-- this throws an exception because "response" is nothing. 
psclient.Close()

任何帮助将不胜感激。

I have a 3rd party webservice (happens to be a peoplesoft EIP service) that I'm trying to call from .net. I've tried using a service reference and the old web reference to call this service and every time I call it I get a response of "nothing" back from the service.

I've ran the service call through SoapUI and it works fine. I've captured the network traffic using Fiddler and notice that when i call the service from SoapUi or from .Net I get the same resulting xml back from the call. So that means the call is working. I've turned on tracing and logging within WCF and I'm not seeing any errors. Nor is it throwing an exception.

So my theory is that .net is having a hard time translating the xml from the service back into a .net object.

Here is a snippet of my code:

Dim psclient As New psService.LSS_WEBORDER_PortTypeClient

Dim psreq As New psService.LSS_WEBORDER_REQ_MSG_TypeShape
psreq = New psService.LSS_WEBORDER_REQ_MSG_TypeShape

Dim orderinfo(1) As psService.Transaction_TypeShape

Dim captureid As String = "WB" & Right(Guid.NewGuid.ToString, 8)
orderinfo(0) = New psService.Transaction_TypeShape
orderinfo(0).LSS_WEBOHDR_WRK = New psService.LSS_WEBOHDR_WRKMsgDataRecord_TypeShape
orderinfo(0).LSS_WEBOHDR_WRK.CAPTURE_ID = New psService.CAPTURE_ID_TypeShape
orderinfo(0).LSS_WEBOHDR_WRK.CAPTURE_ID.Value = captureid

psreq.MsgData() = orderinfo

Dim response As New psService.LSS_WEBORDER_RESP_MSG_TypeShape
response = psclient.LSS_WEBORDER_OP(psreq)
response.ToString() <-- this throws an exception because "response" is nothing. 
psclient.Close()

Any help would be appreciated.
