我有一个名为Direccion
的表,其他名为Cliente
,每个都像这样定义
public class Direccion
{
public short IdDireccion { get; set; }
public short IdCliente { get; set; }
public string Descripcion{ get; set; }
public virtual ICollection<Cliente> Cliente { get; set; }
}
public class Cliente
{
public short IdCliente { get; set; }
public string Descripcion { get; set; }
}
现在我想要完成的是通过生成匿名类型
来查询此输出id <----could be idCliente or idDireccion
Descripcion <----could be the description of cliente or Direccion
idFK <---- the id of direccion related with cliente
但是当我从Direccion
导航到Cliente
时,我开始遇到麻烦,因为这个关系给了我收藏,我不知道如何使表达式处理集合到那个类型我期待哪个是Cliente
这是我失败的尝试:
var x= (from d in Direccion
where d.Activo == true select d.Cliente).Select( x => new { x.IdCliente })
var x = (from d in db.Direccion
where d.Activo == true
select d).AsQueryable().Select(xx => new { d.IdCliente });
答案 0 :(得分:3)
尝试使用SelectMany方法:
var x = from d in db.Direccion
where d.Activo == true
from c in d.Cliente
select new
{ c.IdCliente,
c.Descripcion };
