使用继承类

Question

的dbset可以说我有一类食品

public class FoodsContext : DbContext, IUnitOfWork 
{ 
    public DbSet<Consumer> Consumers {get; set;} 
} 

，并有一流的水果

public class FruitsContext: FoodsContext 
{ 
    public DbSet<Price> Prices {get; set;} 
} 

然后在我的仓库 可以说我有

public class SampleRepository 
{ 
    private readonly FruitsContext _dbFruits = new FruitsContext(); 

    public void foo() 
    { 
     _dbFruits.Prices.doanything; 
     //how can i use Consumers table that has been set in Foods class 
    } 
} 

在我的存储库类中，我想访问消费者的值表，而不创建食物类的实例。我怎样才能做到这一点？

我曾在某个项目中看到过这个，但我现在还不太记得。有人能提出一些建议吗

Answer 1

你也可以做

public void foo() 
{ 
    _dbFruits.Prices.doanything; 
    //how can i use Consumers table that has been set in Foods class 
    _dbFruits.Set<Consumer>.doanything; 
} 

Answer 2

它看起来像普通的继承对我说：

public void foo() 
{ 
    _dbFruits.Prices.doanything; 
    //how can i use Consumers table that has been set in Foods class 
    _dbFruits.Consumers.doanything; // this should work 
}
