反序列化JSON不同的结构，但在C＃中使用相同的名称

Question

I am working, in C#, with some API and it returns "Errors" in JSON with 404 and 200(!) status code, but with different structures.

1) HTTP Status 200:

{ "Errors": "Duplicated" }

2) HTTP Status 200:

{ "Errors": {"some_key":"Invalid"} }

3) HTTP Status 404:

{ "Errors": "some_key1":["Invalid"], "some_key2":["Invalid"] }

1 - Maps to String - OK, but not to Dictionary<string,string> 2 - Maps to Dictionary<string,string> , but not to string 3 - Maps it to ModelState Dictionary<string,List<string>> OK, as the StatusCode is diff (I rename "Errors" in Json string and map it to diff property name.

The only issue is with case 1 and 2 as both are returned with the same HTTP Status code and the same node name "Errors".

Have anybody worked with these cases? How do you handle them? Is there any Netwon Json deserialzier setting to flatten Case 2 to just string or Case 1 into dictionary with 1,2,3.. autgenerated keys?

Any other idea?

Cheers

Make your property a dynamic object. https://msdn.microsoft.com/en-us/library/dd264736.aspx . Then based on what properties are available you can convert it or can read the properties directly off the dynamic.
