我有两个C＃类

public class SearchResult
{
    public int? EntityId { get; set; }
    public string Name { get; set; }
    public Address RegisteredAddress { get; set; }
}

和

public class Address
{
    public int? AddressId { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string Address3 { get; set; }
}

在dbContext调用中使用它，以通过EF5映射数据库中的返回对象

using (DbEntities db = new DbEntities())
{
    querySearchResult = db.Database.SqlQuery<SearchResult>(
        @"SELECT e.entity_id AS EntityId, e.entity_reg_name AS Name,
              a.address_1 AS [RegisteredAddress.Address1]
          FROM
              entity AS e
              LEFT JOIN address AS a ON e.entity_reg_addr_id = a.address_id",
        objectParameterList.ToArray()).ToList();
}

我遇到的问题是，即使返回了地址数据，我似乎也无法获得映射的地址对象。searchResult映射的其他属性很好。
