Serialize/deserialize IPagedList<T> using JSON.NET

[ronaldme]

I am strugling with the serialization of IPagedList using JSON.NET.

Also asked a question on StackOverflow(1) as it is maybe not an issue with this library per se, but that I have to implement a custom serializer/deserializer to make it work.

I have the following use case, I want to serialize/deserialize my IPagedList of T using JSON.net (Newtonsoft.Json). This seems not to be working. It does not serialize everything, only the items (or with my own ContractResolver, the object with empty properties).

A test case:

var list = new List(Enumerable.Range(1, 1000));
var paged = list.AsQueryable().ToPagedList(3, 10);

var json = JsonConvert.SerializeObject(paged); (output: [21,22,23,24,25,26,27,28,29,30])
var obj = JsonConvert.DeserializeObject<PagedList>(json);

Questions:

1. Why do only the items get serialized? (cannot serialize back to the PagedList because of that, I guess)
2. Is there a 'known' solution to serialize the pagedlist?

Found (2) which correctly makes me serialize the PagedList but that cannot convert back to the IPagedList, are there implementations for serialization for this library?

+1 I think this is important.
Would be essential having this done.
Thank you.

This is not a bug. JSON support only simple arrays and cannot serialize complex object which inherite from array type. You should resolve it manual. For ex. serialize separately PagedListMetaData object and elements.
