首先，这对希望了解这一点的人有所帮助：
我有一个API，我需要查询各种数据点（CrunchBase），我获取了URL并使用此工具http://json2csharp.com/#为其生成了类（返回了与该JSON URL交互所需的类）接下来，我需要使用服务，请斯科特·汉塞尔曼（Scott Hanselman）进行救援，使用有关如何执行此操作的博客文章http://www.hanselman.com/blog/NuGetPackageOfTheWeek4DeserializingJSONWithJsonNET.aspx接下来，我将两者放在一起，并进行了一些修补，以使我可以查询CrunchBase API以获取所需的部分信息。目前，我只是通过控制台应用程序来确定逻辑，因为我打算稍后将其包装在.dll中，以便在将信息提供给MVC站点的DataModel项目的DAL层中使用。
问题：到目前为止，除了我不知道我该怎么做才能遍历从JSON终结点返回的子对象之外，目前为止都可以工作。我的代码按原样发布给想要查看实现的任何人（我无法在网上找到任何示例来调用C＃中的CrunchBase API）此代码在我知道需要一些foreach循环的地方被评论。但是我发现的所有示例都不适用于我。任何有关如何执行此操作的方向都非常感谢。一个示例或代码更正对帮助自己和其他人自己解决其余问题大有帮助。另一个问题，这可以全部用c＃完成吗？还是需要使用其他方法？
此代码中使用的端点是“ http://api.crunchbase.com/v/1/company/” + CompanyName +“。js”提前非常感谢，在询问之前，我竭尽全力。

最佳答案
我想您正在寻找类似的东西，如果没有，则应指定您的问题，或告诉以下内容为何不起作用或发生哪个错误...
foreach (var office in j.offices)
{
Console.WriteLine("Description: {0}", office.description );
//...
}
但是可以肯定的是：可以使用C＃完成！
对于那些
List<object>属性，您应该将相应的类添加到模型（您确实生成的类），或者尝试将这些对象强制转换为JsonObject或sth。像那样。 （请检查VS以查看实际类型。）
