C# 访问WSDL文件的SOAP客户端

我在C#中的ASP.NET中工作，在sabre的webservices中，我尝试调用wwebservice airlowfaresearch，这很好，但我会努力让讨价还价搜索器获得最大备用日期，我使用了以下内容：

webservices.sabre.com/wsdl/sabreXML1.0.00/tpf/OTA_AirLowFareSearchLLS1.13.1RQ.wsdl

并更改了

：BargainFinderMax_ADRQ

的操作，这是我的请求：

<?xml version="1.0" encoding="UTF-8"?>

我得到这个错误：

对象引用未设置为对象的实例

而xml响应仅限于此：

<?xml version="1.0" encoding="UTF-8"?>
<OTA_AirLowFareSearchRS xsi:nil="true" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>

此问题的原因是什么？

以下是您的工作BFM_AD请求示例：

我建议您从工作请求开始，在获得成功的响应后，您应该根据需要专门处理该请求。

谢谢您的回答，但我知道这应该是请求，但我希望它以这样的方式出现，但在C中，我不知道如何做，因为我没有放任何回执，请让我清楚，您使用的是.NET wsdl生成的请求模型类，因此无法使用http客户端发出普通的SOAP XML请求，对吗？
