web-services - C# + Java 服务soap 消息互操作性，soap 消息没有在c# APP + SGEN 中反序列化

Question

我在我的 c# 应用程序中使用的 Java Web 服务之一有一个返回类型“marketCalendar”，其定义如下 wsdl. WSDL 的 Target 名称空间是http://www.xyz.com

问题# 我的 c# 应用程序调用 java webservice 上的 GetMarketCalendar 方法，确实看到了 XML 响应，但无法将其反序列化回 marketCalendar 响应。所以我开始使用XGen 生成的类进行挖掘。

我注意到对于country、exchange、calendarDay类型- c# 的默认反序列化器将肥皂响应中的命名空间与空字符串进行比较，即

if (((object) Reader.LocalName == (object)id84_country && (object) Reader.NamespaceURI == (object)id2_Item)) {

其中传入的是 Reader.NamespaceURI = " http://www.xyz.com " 和 id2_Item = Reader.NameTable.Add(@""); 即空。由于比较失败，反序列化也失败。有什么解决办法吗？

这是 C# XMLSerializer 错误还是 wsdl 中的 marketCalendar 定义有问题？
