我试图解析WSDL，沿着给定here的示例的行。
作者在评论中指出，该示例无法深入研究复杂的数据类型。
事实上，当我运行该示例时，它似乎甚至不能处理简单的数据类型。
我在示例中使用的System.Web.Services.Description.ServiceDescription类中搜索过，但在运行时找不到任何实际参数或返回类型信息。我认为我可能需要对xsd文件进行一些手动解析？
谷歌和stackoverflow似乎缺乏如何以编程方式深入研究复杂类型的完整示例，所以......我应该怎么做？
这不是很好 - 但它完成了工作（希望如此;）。我将此代码部分基于您提供的链接，然后添加一些递归来解析模式中包含的不同类型，以及内部元素及其数据类型。这肯定没有考虑到XML模式中的所有可能性，但我认为它足以说明如果需要可以增加复杂性。
我希望这有帮助！！！！

你想用解析的结果做什么？例如，如果要将类型存入内存以便使用它们，则可以使用ServiceDescription.Read和导入程序来编译程序集。
您可以在此PowerShell脚本中看到此类方法的示例：
