You can use JSON.stringify when you posting data to pass arry of objects to controller.

$.ajax(
{
    url: 'Test/Questionbank',
    data: JSON.stringify({checkboxarray  : checkboxarray }),
    contentType: 'application/json',
    dataType: 'json',
    type: 'POST',
    success: function (data) {
        alert("success");
    },
    error: function () { alert('error');}
});
