$.ajax({
url: <Url of the action>,
type: "POST",
data: JSON.stringify([1,2,3]),
dataType: "json",
contentType: 'application/json; charset=utf-8'
});
and in the action.
public ActionResult ReceiveIntArray(int[] ints)
{
...
}
mvc should parse the json automatically.
check out this question.

Doesn't work from my code... can't catch the reason. When I enter the method parameter is null.

sorry you would have to use JSON.stringify([1,2,3]) i have edited the answer

@Daniel it works for me too but, i have one question. why didn't matter what array name is ("ints")? Normally if data: { BasvuruId: BasvuruId}, in js , Variable name must be same (BasvuruId) in action.

dataType:"json" is often overlooked... at least, by me.
Try solution from this question:
Set the
traditionalproperty to true before making the get call. i.e.:jQuery.ajaxSettings.traditional = true $.get('/controller/MyAction', { vals: arrayOfValues }, function (data) { ... }

Code doesn't send values. Link is nice.
The way I'm doing it is with a simple input:hidden element
<input type="hidden" name="elements" value='@String.Join(",", ViewBag.MyArray)' />
And in the JavaScript code I'm passing it as a string:
$.ajax({
type: "POST",
url: '/Controller/Method',
data:
{
recipients: $("input[name=elements]").val()
},
traditional: true,
success: updateSelected
});
And finally I just Split the elements like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Method(string elements)
{
IList<long> selected = elements.Split<long>(',');
...
}

The simplest way would be to send a delimited (commas, possibly) string list of the ints as an argument on a GET request, then use Sting.Split() to parse them on your C# MVC receiver.
So, for example
$.get("/path-to/receiver/", { myArray: myArray.toString() } );
Then, on the server, use
string[] stringArray = Request.QueryString["myArray"].ToString().Split(',')
to extract the values to a string array, then Int32.TryParse to finally get an array of ints.

Doesn't send values. There is nothing to parse.
Ben Parsons
This is just an example - you would need to replace "myArray" etc with your own values. The request url should be something like /path-to/receiver/?myArray=your,array,contents
Try this solution :
var Array = [10, 20, 30];
$.ajax({
type: "Post",
datatype: "Json",
url: <Url of the action>,
data: JSON.stringify(Array),
contentType: 'application/json; charset=utf-8',
});
