Convert a SQL query into a Linq to SQL instruction

I need to convert the below SQL query into a Linq query

select *
from bancos 
where codigobanco in 
   (select distinct codigobanco开发者_Python百科
   from headerarquivo
   where (MONTH(datahorageracao)=12) and (YEAR(datahorageracao)=2010))

How could I do to transform this SQL query in a Linq query ?

assuming that datahorageracao is a datetime you didnt post the properties or the domain model but want you want is something like this:

from banco in bancos
let queryauxiliar = (from arquivo in headerarquivo where (arquivo.datahorageracao.Month = 12) && arquivo.datahorageracao.Year = 2010 select arquivo.codigobanco)
where queryauxiliar.Any((val)=>banco.codigobanco == val.codigobanco)
select new Banco()
{
   NomeProp = banco.valor
}

Assuming datahorageracao is of type DateTime.Two different ways you can write LINQ code first using lambda expressions and second using query expression syntax either way works -

//Lambda Expression way get distinct codigobanco...
var codigobancolist =Context.headerarquivo.Where(c=>c.datahorageracao.Month ==12 && c.datahorageracao.Year==2010).Select(c=>c.codigobanco).Distinct();

//Query Expression way to get actual data...
    var data= from b in bancos 
              where b.codigobanco.Contains(codigobancolist)
              select b;

var banco = from c in bancos
            where headerarquivos
                  .Select(o => o.codibanco)
                  .Where(o.MONTH(datahorageracao)=12) and (o.YEAR(datahorageracao)=2010))
                  .Contains(c.codibanco)
            select c;

Pretty sure that should do it.
