get a method to return json in C# and asp.net MVC 2 or 3 -

i use json return allot of results when building website, find myself writing a lot of code this:

 return json((                     s in searchresults                     select new {                        orderid = s.orderid,                       orderrealid = s.orderrealid,                       orderstatus = s.orderstatus,                       orderdate = s.orderdate,                       ordervenue = s.venuename + " - " + s.venuelocation + " (" + s.venuenumber + ")",                       orderstatustext = s.statusordervalue                     }                 ), jsonrequestbehavior.denyget); 

what this:

 public string resultstojson<t>(hashtable fields){                     s in t                     select new {                        // loop through hash table                     } } 

and call function whatever ienumerable results have question on right lines here, best possible way makes no sense writing in mvc , oop keep rewriting code ? in ? time.

many thanks

what types hashtable (dictionary<t,t> since 2.0) hold? if it's plain dictionary<string,string> write json trivially.

if has set of types have more types inside, way down leaf nodes worth looking @ json.net library instead, has far more advanced json capabilities standard .net json serializer.
