問題描述

我試圖弄清楚如何使用SAP Web服務。 我有一個.WSDL文件，用於在SAP中查找某些信息。

我的.WSDL文件： 

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="Customer_Out" targetNamespace="..." xmlns:p1="...." xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">

</wsdl:definitions>

我在.NET項目中添加了一個服務引用，該服務引用了.WSDL文件。 這創建了一個命名空間，該命名空間使我可以創建幾個類的實例（總共9個）。

我似乎找不到如何傳遞請求並接收相應的響應。 我應該解析這些請求/響應嗎？ 我知道本教程，但它與我正在處理的文件並不完全對應。

請求看起來像這樣： 

<man:MT_CustomerRead_request>
         <RowLimit>100</RowLimit>
         <!--Optional:-->
         <!-- <CustomerId>?
         <!--Optional:-->
         <Name>Dell*</Name>
         <!--Optional:-->
         <!--Optional:-->
         <AccountGroup>ABC</AccountGroup>
</man:MT_CustomerRead_request>

提前致謝

我只是在研究這個主題，下面是一個有關如何在.NET（C＃）中創建請求和調用SAP服務的示例。 

// Create the client
SapServiceReference.ECC_WS sapService = new SapServiceReference.ECC_WS();
sapService.Credentials = new NetworkCredential("Account", "Password");

// Prepare the parameters
SapServiceReference._parameters param = new SapServiceReference._parameters();
param.id = 1;
param.action = "R";

// Call SAP service
SapServiceReference._ws_Response response = sapService._someFunction(param);
string result = response.EvDescriptionText.Tdline;
