Pass an array of integers to ASP.NET Web API?

Question

I have an ASP.NET Web API (version 4) REST service where I need to pass an array of integers.

Here is my action method:

Answer 1

In case someone would need - to achieve same or similar thing(like delete) via POST instead of FromUri, use FromBody and on client side(JS/jQuery) format param as $.param({ '': categoryids }, true)

c#:

public IHttpActionResult Remove([FromBody] int[] categoryIds)

jQuery:

$.ajax({
        type: 'POST',
        data: $.param({ '': categoryids }, true),
        url: url,
//...
});

The thing with $.param({ '': categoryids }, true) is that it .net will expect post body to contain urlencoded value like =1&=2&=3 without parameter name, and without brackets.
