Question

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'alert'实例，但它的'info'属性始终为null。使用Fiddler，我可以检查XML并看到从服务器返回一个元素（见下文）。一个可能相关的注释：'info'在wsdl中定义为0..unbounded'alert'，并在代理中生成一个数组。此外，行为与使用WSE3的.net 2.0样式的Web引用相同。

作为一种解决方法，我编写了自己的XML序列化的类（即实现IXmlSerializable），并且这些类按预期反序列化（即info！= null）。然而，手工编码这些是容易出错的并且具有一些其他缺点。

为什么生成的代理类不能正确反序列化？纠正这个问题的最佳方法是什么？

DMIS未正确实施警报对象。

他们的版本使用大写A <Alert>，而绿洲将其定义为<alert>

命名空间也存在问题，您需要确保包含正确的命名空间以进行反序列化。

为什么为此WSDL生成的.NET代理会丢弃一些数据？
