适当的代码首先相关类/表的EF6结构 [英] Proper Code First EF6 structure for related classes/tables
本文介绍了适当的代码首先相关类/表的EF6结构的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
public class Person
{
[Key]
public int Id {get;组; }
public string FirstName {get;组; }
public string LastName {get;组; }
public int TitleTypeId {get;组; }
}
public class TitleType
{
public int Id {get;组; }
public string Name {get;组;
}
标题类包含先生,夫人,MS之类的内容。等等。
定义这些类的正确方法是什么,以便我可以使用Linq从TitleType表中调用所需的标题name? p>
ie person.Title.name
解决方案
public class Person
{
[Key]
public int Id {get;组; }
public string FirstName {get;组; }
public string LastName {get;组; }
public TitleType标题{get;组; }
}
EF将创建额外的列来自动处理外键。 p>
I have a two classes. A person class and a Title class.
public class Person
{
[Key]
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public int TitleTypeId { get; set; }
}
public class TitleType
{
public int Id { get; set; }
public string Name { get; set; }
}
The title class contains things like "Mr., Mrs., MS.,etc.."
What is the proper way to define these classes so that I can use Linq to recall the desired title "name" from the TitleType table?
i.e. person.Title.name
解决方案
public class Person
{
[Key]
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public TitleType Title { get; set; }
}
EF will create additional column to handle Foreign Key for you automatically.
