Linq-分组并获取对象列表

Question

I have a list of L_CabecDocumento and each one of them has a L_CabecJob . I want to get all unique L_CabecJob from each and every L_CabecDocumento (i have a Where condition).

The problem is that i can't cast it to a List<L_CabecJob>() What am i doing wrong? Thanks

var lista = (from d in appADO.L_CabecDocumento
               where d.L_TipoEntidadeId == 2  && d.Entidade == fornecedor
               group d by d.CabecJob into c
               select c.Key ).ToList() ;

return  (List<L_CabecJob>)lista;

Answer 1

instead -

return  (List<L_CabecJob>)lista;

use -

return lista.Cast<L_CabecJob>();

next time english variables might help us understand youre code better ;)
