如何反序列化JObject到.NET对象 [英] How to deserialize an JObject to .NET object

问题描述

我愉快地使用 Newtonsoft JSON库。 例如，我将创建一个 JObject 从.NET对象，在这种情况下异常的情况下（可能是也可能不是一个子类）

I happily use the Newtonsoft JSON library. For example I would create a JObject from an .NET object, in this case a instance of Exception (might or might not be a subclass)

if (result is Exception)
    var jobjectInstance = JObject.FromObject(result);

现在我知道该库可以反序列化JSON文本（即字符串）为对象

now I know the library can deserialize JSON text (i.e. a string) to an object

// only works for text (string)
Exception exception = JsonConvert.DeserializeObject<Exception>(jsontext); 

但我在找的是：

but what I am looking for is:

// now i do already have an JObject instance
Exception exception = jobjectInstance.????

那么很显然，我可以从 JObject 返回JSON文本，然后使用反序列化功能，但似乎倒退到我。

Well it is clear that I can go from on JObject back to JSON text and then use the deserialize functionality, but that seems backwards to me.

推荐答案

根据这个<一个href="http://www.west-wind.com/weblog/posts/2012/Aug/30/Using-JSONNET-for-dynamic-JSON-parsing">post,这是好多了：

According to this post, it's much better now:

// pick out one album
JObject jalbum = albums[0] as JObject;

// Copy to a static Album instance
Album album = jalbum.ToObject<Album>();

文档： JSON转换到一个类型
