我正在尝试按照给出的示例 here 来解析 WSDL .
作者在评论中指出,该示例无法深入到复杂的数据类型。
事实上,当我运行该示例时,它似乎甚至无法处理简单的数据类型。
我在示例中使用的 System.Web.Services.Description.ServiceDescription 类中四处寻找,但在运行时找不到任何实际参数或返回类型信息。我想我可能需要对 xsd 文件进行一些手动解析?
google 和 stackoverflow 似乎都缺乏如何以编程方式深入了解复杂类型的完整示例,所以......我应该怎么做?
最佳答案
这不是很漂亮 - 但它完成了工作(希望 ;)。我将此代码部分基于您提供的链接,然后添加了一些递归来解析架构中包含的不同类型,以及内部元素及其数据类型。这绝对没有考虑到 XML 模式中的所有可能性,但我认为它足以说明您可以在必要时增加复杂性。
希望对您有所帮助!!!!
