我正在努力消費SAP Web服務。我經歷過很多教程，並在MSDN上的多個線程，但我不能找到我的問題的解決方案：消費SAP Web服務 - 請求發送兩次，每次都失敗
運行我的程序與此錯誤結束：

什麼似乎不可思議對我說：
我測試了通過SoapUI創建的請求。我不得不刪除的評論，然後正常工作：
<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>
所以最後我的代碼看起來是這樣的：
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);
的是，在Web服務請求發送第二個錯誤兩次：一次一次沒有認證。
它並不完全適合我，造成
parameter = client.ZTST_MASS_USER_CREATE(parameter);
我計劃兩個請求;第二個是由服務器（先不進行身份驗證）接受，但返回一個錯誤：
