首先，我对Json.Net没有太多经验，所以我提前道歉。我可以很好地反序列化基本对象，但这里是我遇到问题的地方。。。
我有一个疯狂的返回JSON，我不知道如何反序列化。我把它贴在下面了。我使用C#和Newtonsoft.Json（Json.Net）NuGet包来编写一个应用程序来使用这个Json。
基本上，JSON按"类型"（"D"、"M"、"O"、"R"、"G"或"A"）划分，该类型有一个嵌套的JSON对象（"IO"），其中包含一组关于类型状态的相关信息。IO数据是一个列表。

我想要一个名为Status的对象，它将包含每个"类型"（D、M、O、R、G或A）的字段。请参阅下面的示例类，其中"D"类型是Digital类，"M"类型是Monitoring类。
public class Status
{
public ObservableCollection<Digital> Digital {get;set;}
public ObservableCollection<Monitoring> Monitoring{get;set;}
etc....
}
public class Digital
{
// I'll replace the # in the JSON with "number" or something
// before deserializing
public string # {get;set;}
public string Desc {get;set;}
public string Ss {get;set;}
public string Dt {get;set;}
public string InAlarm {get;set;}
}
然后，我想通过这样做来访问嵌套对象。在这个例子中，我想要"D"JSON类型，以及"IO"#1:的数据
var _statusObjMagic = new Status();
// Go get the JSON and deserialize it.. build up the _statusObjMagic
Some magical code here...
// Get some data from the JSON response
string inputOneDescription = _statusObjMagic.Digital[0].Desc;
反序列化这个JSON并获得上述结果的最简单方法是什么？也许我错了，有一种更简单的方法可以反序列化JSON并访问所有数据。我完全开放。
您需要有一个合适的类来反序列化为.
我使用JSON 2 C#为您生成了一个。
public class IO
{
[JsonProperty(PropertyName = "#")]
public int Id{ get; set; }
public string Desc { get; set; }
public int SC { get; set; }
public string DT { get; set; }
public object InAlarm { get; set; }
public string VS { get; set; }
}
public class RootObject
{
public string Type { get; set; }
public List<IO> IO { get; set; }
}
在C#中，#不是有效的属性名称。因此，我使用JSON.NET提供的JSON属性来告诉JSON.NET如何转换它
然后可以反序列化。
List<RootObject> mylist = JsonConvert.DeserializeObject<List<RootObject>>(json);
