Cant convert LINQ Query var to DataTable

I have the following code:

var _permiso = from P in _db.clsPermiso
               select P;

var _pagina = from P in _db.clsPagina.AsEnumerable()
              select P;

var _perfil = from P in _db.clsPerfil
              select P;

IEnumerable<DataRow> query = from permiso in _permiso.AsEnumerable()
            join perfil in _perfil.AsEnumerable()
                on permiso.ID equals perfil.ID
            join pagina in _pagina.AsEnumerable()
                on permiso.ID equals pagina.ID
            where (permiso.Acceso == true) && (permiso.Perfil.ID == Convert.ToInt32(strIDPerfil))
            select pagina;

I'开发者_开发问答ve been gathering some info on the MSDN page, and it tells me to use IEnumerable<DataRow> and then, asign that query variable into a DataTable var like this:

DataTable _dtResult = query.CopyToDataTable();

But im getting the error at the select pagina statement:

Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<MyApp.Models.clsPagina>' to 'System.Collections.Generic.IEnumerable<System.Data.DataRow>'. An explicit conversion exists (are you missing a cast?)

Thx in advice

Converting enumerables does not necessarily use the implicit conversions that the base types use. You will likely have to explicitly cast the result "pagina" as a DataRow in your LINQ query.

Not knowing your class/type definitions, I'm only guessing, but I believe you want your last line of your LINQ query to be:

select (DataRow)pagina;

Is there a specific reason you want the result as more primitive?
