我在试图弄清楚如何反序列化我对 facebook api 的调用的响应时遇到了很多麻烦。我的 c# 代码如下所示：
FacebookClient client = new FacebookClient();
string path = "SELECT message, type, attachment FROM stream WHERE source_id = " + fbid.ToString();
dynamic result = client.Get("fql", new { q = path });
这就是结果的样子 - 它以 json 形式返回
我需要反序列化这个动态对象，它是一个字符串 json 到 ac# 对象。不知道可以foreach对动态对象进行循环。我还尝试只创建一个对象并将反序列化为我创建的对象。问题是，正如您所看到的，有很多属性大部分时间都没有返回，然后有时它们会被返回。所以 Facebook 返回的 json 总是有不同数量的属性。我尝试了一个for循环，然后通过 response.data.message[1] 之类的方法从 json 中取出对象，但这不起作用。任何想法如何将这个动态对象反序列化为我可以使用的东西？
