【问题描述】：
我使用此 WSDL 向 .NET 项目添加了 WCF 服务引用： https://interop.cmiservices.org/axis/services/CAP1_1?wsdl
它生成代理类等，我可以调用这些方法。但是，当调用“getCAPAlerts”或“getCAPAlert”时，返回值似乎缺少数据。例如，'getCAPAlert' 返回一个 'alert' 实例，但它的 'info' 属性始终为空。使用 Fiddler，我可以检查 XML 并查看从服务器返回的元素（见下文）。一个可能相关的注释：'info' 在 wsdl 中的 'alert' 上定义为 0..unbounded，并且在代理中生成了一个数组。此外，该行为与使用 WSE3 的 .net 2.0 样式 Web 引用相同。
作为一种解决方法，我编写了自己的 XML 序列化类（即实现 IXmlSerializable），并且这些类会按预期反序列化（即 info != null）。然而，手工编码这些很容易出错并且有一些其他的缺点。
为什么生成的代理类不能正确反序列化？纠正此问题的最佳方法是什么？

【问题讨论】：
-
info属性返回一个info对象数组。info对象/类是否可序列化？ -
webservice 是你的，这样你就可以调整 wsdl xsd 架构了吗？
-
抱歉放弃这篇文章。信息也是由 wsdl 工具生成的，不幸的是，不，这不是我们控制的服务。拍得对，这个来源没有正确实现规范。此外，.net 序列化在 0..* 元素方面存在问题...
