c# - Linq projecting to a class -

public class marketviewmodel {     public marketviewmodel()     {     }      public string item { get; set; }     public list<subitem> stationname { get; set; }  }  public class subitem {     public string item { get; set; } }  var active = actives in activestations     group actives.stationname new { actives.market,actives.stationgroupint } g     select new marketviewmodel { item = g.key.market, stationname = g.tolist() }; 

in above linq code, question how project marketviewmodel, see stationname list of subitem.

stationname = g.tolist()

( how re-write piece ?) creates list of subitem objects

edit

activestations entity contains

• stationname(string),
• stationgroupint (int),
• market (string)

---

market stationname stationgroupint ----------------------------------        b              1       c              1       d              1  

you can use select on group g create sub item.

var active = actives in activestations              group actives.stationname new { actives.market,actives.stationgroupint } g              select new marketviewmodel {                   item = g.key.market,                   stationname = g.select(stationname => new subitem {                       item = stationname                   }).tolist()               };
