問題描述
我正在嘗試解析 WSDL，按照給出的示例 這里.
I am attempting to parse WSDL, along the lines of the example given here.
作者在評論中指出，該示例無法深入研究復雜的數據類型.
The author notes, in the comments, that the example is not capable of drilling down into complex data types.
事實上，當我運行該示例時，它似乎甚至無法處理簡單的數據類型.
And in fact, when I run the example, it does not appear to even handle simple data types.
我在示例中使用的 System.Web.Services.Description.ServiceDescription 類中四處尋找，但在運行時找不到任何實際參數或返回類型信息.我知道我可能需要手動解析 xsd 文件?
I have poked around in System.Web.Services.Description.ServiceDescription class, which is used in the example, but cannot find any actual parameter or return type information at run-time. I gather that I may need to do some manual parsing of an xsd file?
google 和 stackoverflow 似乎都缺乏如何以編程方式深入研究復雜類型的完整示例，所以......我應該怎么做?
Both google and stackoverflow appear to lack a complete example of how to drill down into complex types programmatically, so... how should I do this?
推薦答案
這并不漂亮 - 但它完成了工作(希望;).我將此代碼部分基于您提供的鏈接，然后添加了一些遞歸來解析架構中包含的不同類型，以及內部元素及其數據類型.這絕對沒有考慮到 XML 模式中的所有可能性，但我認為它足以說明您可以在必要時增加復雜性.
This is not pretty - but it gets the job done (hopefully ;). I based this code partly on the link you provided, and then added some recursion to parse out the different types included in the schema, as well as the inner elements and their data types. This definitely does not take into account all possiblities in an XML schema, but I think it exemplifies enough that you could add complexity to this if neccessary.
希望對你有幫助！！！！
