asp.net mvc - How do I pass my data to a JsonResult so that it formats correctly -

i using mootools textboxlist in mvc app create autocomplete tag suggester, similar stackoverflow one.

the script uses json suggestions. json string seems expect different able generate. script's demo, should this:

[[32,"science",null,null]] 

but can't figure out how string come out of mvc quite that. best looks more like:

[{"id":11,"text":"science"}] 

with actual field names showing up.

here controller method:

   public jsonresult suggest(string search)     {         jsonresult jsonresult = new jsonresult();          var tags = t in db.tags                          t.text.contains(search)                          select new {id=t.tagid, text=t.text};          var result = dosomethingto(tags); // <---????????          jsonresult.data = result;          jsonresult.jsonrequestbehavior = jsonrequestbehavior.allowget;          return jsonresult;     } 

i've tried several variations of passing variables jsonresult.data without luck. i've tried arrays, custom objects, etc. i'm not getting it. i'm it's

edit: should have said "i'm it's easy."

it's array of arrays of objects. generate this:

return json(new[] { new object[] { 32, "science", null, null } }); 

and within select action try along lines of:

public actionresult suggest(string search) {     var tags = t in db.tags                t.text.contains(search)                select new object[] { t.tagid, t.text };      return json(tags.tolist(), jsonrequestbehavior.allowget); }
