使用Sap WebService – 请求发送两次并且每次都失败

我正在努力消耗一个sap webservice。 我已经通过很多教程和msdn上的许multithreading，但我无法找到解决我的问题的方法：

运行我的程序最终会出现此错误：

CommunicationException not handled. -> unknown Messageversion System.ServiceModel.CommunicationException wurde nicht behandelt. HResult=-2146233087 Message=Unbekannte Nachrichtenversion.

对我来说似乎很奇怪：

我测试了通过SoapUI创建的请求。 我不得不删除评论，然后它工作正常：

所以最后我的代码看起来像这样：

  var binding = new BasicHttpBinding(); binding.MaxReceivedMessageSize = int.MaxValue; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic; binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; binding.AllowCookies = true; var address = new EndpointAddress("http://host/relativeurn); //create client ServiceReference2.ZTST_MASS_CREATE_USER_gutClient client = new ServiceReference2.ZTST_MASS_CREATE_USER_gutClient(binding, address); Console.WriteLine("Created Client"); //define credentials client.ClientCredentials.UserName.UserName = "User"; client.ClientCredentials.UserName.Password = "PWD"; ServiceReference2.ZTST_USER_PWD[] parameter = new ServiceReference2.ZTST_USER_PWD[2]; parameter.Initialize(); parameter[] = something client.open(); parameter = client.ZTST_MASS_USER_CREATE(parameter); 

第二个错误是对Web服务的请求被发送两次：一次，一次没有validation。

我通过这个post： http ： //social.msdn.microsoft.com/Forums/vstudio/en-US/d9f99777-f702-4c0e-8198-b110f8eacdd9/net-c-console-application-calling-sap-webservice？论坛= WCF

它不适合我，原因

  parameter = client.ZTST_MASS_USER_CREATE(parameter); 

我的程序有两个请求; 第二个被服务器接受（第一个没有validation），但返回错误：

                                        false  # 3EB6184C46517B16E1000000AC10FEEB    false true no false                                                                                

更新：

这是我的appl.config

愚蠢的我！ 如果您在需要WEB服务参考时选择添加服务引用而不是Web服务引用，则会发生上述错误。 要将webREferenz添加到项目中：
