WebService Client返回空的Result对象，但是消息正文具有内容

Question

我正在使用内置的Web服务参考客户端与第三方Web服务进行通信。

工作流程包括连续拨打3个电话。第一个调用工作正常，但是第二个调用返回空对象，即使消息包含请求的数据也是如此。我很好奇它是否是某种模式不匹配导致的，或者它是否是我的代码中的错误。

这是问题部分的wsdl。

这是呼叫代码

根据我在某处遇到的一些调试建议，我注册了一个IClientMessageInspector，然后输入

private void WaitForJob(string user, string password, string jobId)
        {
            RMJQueryJob1.QueryJobPortTypeClient client = new RMJQueryJob1.QueryJobPortTypeClient();
            client.Endpoint.EndpointBehaviors.Add(new FaultFormatingBehavior());
            client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
            client.ClientCredentials.UserName.UserName = user;
            client.ClientCredentials.UserName.Password = password;
            using (System.ServiceModel.OperationContextScope scope = new System.ServiceModel.OperationContextScope(client.InnerChannel))
            {
                var httpRequestProperty = new HttpRequestMessageProperty();
                httpRequestProperty.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " +
                             Convert.ToBase64String(Encoding.ASCII.GetBytes(client.ClientCredentials.UserName.UserName + ":" +
                             client.ClientCredentials.UserName.Password));
                OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;

                RMJQueryJob1.QueryJobRequest queryJobRequest = new RMJQueryJob1.QueryJobRequest();
                queryJobRequest.JobId = jobId;
                queryJobRequest.JobFields = new string[] { "Status", "Queue" };

                // THIS RETURNS NULL
                var result = client.QueryJob1(queryJobRequest);

            }
        }
