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

Easy way to send array params to web api

API

public IEnumerable GetCategories([FromUri]int[] categoryIds){
 // code to retrieve categories from database
}

Jquery : send JSON object as request params

$.get('api/categories/GetCategories',{categoryIds:[1,2,3,4]}).done(function(response){
console.log(response);
//success response
});

It will generate your request URL like ../api/categories/GetCategories?categoryIds=1&categoryIds=2&categoryIds=3&categoryIds=4
