How to get a list of object with AJAX in ASP.NET MVC

I am trying to generate a list with AJAX and post it to controller. Here is my code so far;

var objects = new Array();

here is a loop {
var object = {
            a: 1,
            b: 2,
            c: 3
        };

objects[i] = object;
i++;
}

 $.ajax({
        type: "POST",
        url: "/Controller/Poster",
        cache: false,
        dataType: 'json',
        contentType: 'application/json; charset=utf-8',
        data: JSON.stringify(objects),
        success: function (result) {
            alert("posted");
        }
    });

Am I following the right way till here?

And in back end I created a model class;

public class ObjectModel
{
    public int a {get; set;}
    public int b {get; set;}
    public int c {get; set;}
}

Now I am trying to get this object list to my controller. After a research I tried create a controller method that takes an object list as parameter;

 [HttpPost]
 public JsonResult Poster(List<ObJectModel> olist)
    { 
    }

But I can't define a list in my controller. What am I supposed to do from now? And should I make any changes in my code?

Thanks!

I added System.Collections namepace to my controller. And I can define List now. After I added [HttpPost] attribute to my method and make public my class properties now there isn't any problem. My main problem was the System.Collections namespace. I successfully passed my object list to my controller.

Try this 

data: objects

instead of

data: JSON.stringify(objects)

Add attribute to Poster

[HttpPost]
public JsonResult Poster(List<ObJectModel> olist)

Change ObjectModel

public class ObjectModel
{
    public int a {get; set;}
    public int b {get; set;}
    public int c {get; set;}
}
