Question

ef code first 怎样指定哪些类生成数据表？那些不生成数据表

Answer 1

TPH(Table Per Hierarchy)

TPH：基类和派生类都映射到同一张表中，通过使用鉴别列来识别是否为子类型。这是Code First默认规则使用的表映射方法。

public class Lodging
{
public int LodgingId { get; set; }
[Required]
[MaxLength(200)]
[MinLength(10)]
public string Name { get; set; }
public string Owner { get; set; }
public decimal MilesFromNearestAirport { get; set; }
public int DestinationId { get; set; }
}
public class Resort : Lodging
{
public string Entertainment { get; set; }
public string Activities { get; set; }
}
