我在使用SAP Web服务时遇到了一些困难。我已经通过许多教程和MSDN上的许多线程，但我无法找到解决我的问题的方法：
运行我的程序会出现以下错误：

CommunicationException not handled.

我觉得奇怪的是：
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：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"   xmlns:urn="urn:sap-com:document:sap:rfc:functions">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:ZTST_MASS_USER_CREATE>
         <USER>
            <item>
            <!-- erased comment -->
               <USER>o</USER>
               <PWD>kkkk</PWD>
            </item>
         </USER>
      </urn:ZTST_MASS_USER_CREATE>
   </soapenv:Body>
</soapenv:Envelope>

型
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);

型
第二个错误是对webservice的请求被发送了两次：一次有认证，一次没有认证。
我通过这个线程：http://social.msdn.microsoft.com/Forums/vstudio/en-US/d9f99777-f702-4c0e-8198-b110f8eacdd9/net-c-console-application-calling-sap-webservice?forum=wcf
它并不完全适合我，因为

parameter =   client.ZTST_MASS_USER_CREATE(parameter);

我的两个请求的程序;第二个被服务器接受（第一个不进行身份验证），但返回一个错误：

愚蠢的我！如果你选择添加服务引用而不是Web服务引用，当你需要一个Web服务引用时，上面的错误就会发生。要将webREferenz添加到项目中：
