how to pass parameter like 'before' and 'limit' in Manatee Trello methods

first of all, thanks to @gregdennis. I use Manatee Trello namespace to query and get Actions from Trello board. there is a limitation to getting entities on each request (50 by default). In Online API documentation I read there are several parameters like 'limit' and 'before'. How I passing these parameters to methods in my code, my sample fetch code is here:

    Board board = new Board(boardId);
    var actions = board.Actions.ToList();

There are a few extension methods on various collection types that will modify the API queries to add these parameters.

The first you're looking for is Limit(this ReadOnlyActionCollection, int). Just pass in the number of actions you want. Valid values (per the API) are 0-1000.

The second is Filter(this ReadOnlyActionCollection, DateTime?, DateTime?) which will allow you to filter on since (start) and before (end). (The API docs say that lastView is a valid option for the since parameter. This is not supported at the moment.)

Edit

Note that these extension methods work just like LINQ: they return a new instance of the query. The query doesn't execute until the collection is enumerated.

Edit 2

To get any collection you have to have a Trello entity (board, list, card, etc.) first. A collection is meaningless without the object which defines it. For example, boards have lists, lists have cards, cards have checklists, and all of these have actions.

So to get a collection that consists of the 500 most recent actions for a card,

var card = new Card("<ID>");
var actions500 = card.Actions.Limit(500);
foreach(var action in actions500)
{
    Console.WriteLine(action);
}

Edit 3

Okay. I see the problem. I didn't use the this keyword in the Limit() extensions. I'll fix that and publish an updated.

Until then, please use the method statically:

Collections.Limit(card.Actions, 100);

Edit 4

As of Manatee.Trello version 3.0.0, Limit is a property on all collections. The default is 50 for most types.
