如何从数据库中删除实体？ [英] How can I delete entity from data base?

问题描述

嗨！



我是Entity Framework 5的新手。我正在使用ASP.NET MVC的实体框架。

我有很多对多的关系。

  class  Garage 
 {
  public   int  GarageId {获取;  set ;} 
  public   string  GarageAddress { get ;  set ;} 
  public  ICollection< Car>汽车{获取;  set ;} 
} 
 
  class  Car 
 {
  public   int  CarId { get ;  set ;} 
  public   string  CarName { get ;  set ;} 
  public  ICollection< Garage>车库{获取;  set ;} 
} 

汽车可以与不同的车库，车库也可以有很多车。

我的问题我不知道，我怎么能从一个车库删除车并把这辆车留在其他车库。此外，如果我只在一个车库删除汽车和这辆车，它应该从数据库中删除。



请提供一些例子。

谢谢

Hi!

I'm new in Entity Framework 5. I'm using Entity Framework with ASP.NET MVC.
I have relationships Many-To-Many.

class Garage
{
public int GarageId{get;set;}
public string GarageAddress{get;set;}
public ICollection<Car> Cars{get; set;}
}

class Car
{
public int CarId{get;set;}
public string CarName{get;set;}
public ICollection<Garage> Garages{get; set;}
}

Car can be related to different garages, also Garages can have a lot of cars.
My problem I don't know, how can I delete car from one garage and left this car in other garages. Also If I delete Car and this Car only in one garage, it should deleted from DB.

Please provide some example.
Thanks
