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>();
