Passing IEnumerable through Json - asp.net-mvc

Question

I'm making a "Like" button in a simple comment database MVC program.
I'm passins the ID of the comment through to a ActionResult in the HomeController when I hover over the "Like" button. The problem (I think) is that I don't know how to pass the IEnumerable list of Likes to the ajax.
The script and HTML part:
HTML:
Like this
Script:
$(".likes").hover(function (event) {
var Liker = { "CID": event.target.id };
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "/Home/ShowLike/",
data: JSON.stringify(Liker),
dataType: "json",
success: function (data) {
$.each(data.Name, function (value) {
alert(value);
});
},
error: function (xhr, err) {
// Note: just for debugging purposes!
alert("readyState: " + xhr.readyState +
"\nstatus: " + xhr.status);
alert("responseText: " + xhr.responseText);
}
});
});
HomeController -> ShowLike
[HttpPost]
public ActionResult ShowLike(Liker ids)
{
LikesRepository lkrep = new LikesRepository();
IEnumerable<Like> list = lkrep.GetLikes(ids.CID);
return Json(list);
}
LikesRepository
public class LikesRepository
{
CommentDBDataContext m_db = new CommentDBDataContext();
public IEnumerable<Like> GetLikes(int iden)
{
var result = from c in m_db.Likes
where c.CID == iden
orderby c.Name ascending
select c;
return result;
}
public void AddLike(Like c)
{
m_db.Likes.InsertOnSubmit(c);
m_db.SubmitChanges(); //This works
}
}

After diving into the problem more, we found it was actually triggering an internal server error (500). This was caused by a circular reference from serializing the LINQ to SQL objects to JSON. This issue is discussed several times...

An alternate solution is to return the data as lists of strings as they only required the names.
