c# - Update table using linq -


i want update table not working

here code:

public boolean setsectionticksign(decimal trans_id, decimal job_id, string sectioname) {     string sectionames = "";     transcription_master trans_mastr = new transcription_master();     try     {         var trans_master = (from trans_mast in r2ge.transcription_master trans_mast.transcription_id == trans_id && trans_mast.entity_id == job_id select new          {             trans_mast.completed_trans_sections         }).distinct().tolist();         var complt_trans = trans_master.asenumerable().where(dr = > dr.completed_trans_sections != null).tolist();         if (complt_trans.count == 0)          {             if (sectionames == "")              {                 trans_mastr.completed_trans_sections = sectioname;             }         }          else         {             trans_mastr.completed_trans_sections = "," + sectioname;         }         int sc = r2ge.savechanges();     } }

it not update database..what wrong in it??

you should change piece of code such thing:

 var trans_master = (from trans_mast in r2ge.transcription_master                       trans_mast.transcription_id == trans_id                       && trans_mast.entity_id == job_id                       select trans_mast).distinct().tolist();

in case variable trans_maser refference object collection, changes done on object taken ef context, , savechanges give correct result.
