在JSON API调用中循环访问列表<Objects>（CrunchBase）

Question

首先，为了让所有人都对此感兴趣： 我有一个我需要查询各种数据点的API（CrunchBase）使用此工具为它生成类http://json2csharp.com/#（返回需要与该JSON URL进行交互的类）接下来，我需要使用该服务，输入Scott Hanselman进行救援，使用他的博客文章了解如何执行此操作http://www.hanselman.com/blog/NuGetPackageOfTheWeek4DeserializingJSONWithJsonNET.aspx接下来我将两人在一起，并做了一些修补以允许我查询部分所需信息的CrunchBase API。目前我只是用控制台应用程序来制定逻辑，因为我打算稍后将其包装在.dll中，以用于向MVC网站提供信息的DataModel项目的DAL层。

问题：目前为止，除了我不知道我应该怎么做才能遍历从JSON端点返回的子对象。我的代码发布给任何想看到实现的人（我在网上找不到任何用于在C＃中调用CrunchBase API的示例）此代码在我知道需要某些有点foreach循环的位置发表评论但我发现的所有例子都不适合我。任何方向如何做到这一点非常感谢。一个例子或者一个代码纠正对于帮助我自己和其他人自己解决其他问题将会有很大的帮助。另外的问题，这可以全部在C＃中完成，或者我需要使用别的东西 - 如果有的话，你可以推荐额外的后续研究？

此代码中使用的端点是“http://api.crunchbase.com/v/1/company/”+ CompanyName +“。js”非常感谢您的提前，我试了很久， 。

我猜你正在寻找这样的事情，如果不是你应该specifiy你的问题，或者说，为什么下面不工作或发生错误...

foreach (var office in j.offices) 
{ 
    Console.WriteLine("Description: {0}", office.description); 
    //... 
} 

但一个当然：可以用C＃完成！

对于那些List<object>属性，您应该将相应的类添加到您的模型（您生成的类）或尝试将这些对象转换为JsonObject或某物。像那样。 （用VS查看实际类型。）
