[英]Using Generics on a Repository base class
I have the following model where I just modified my IEntity interface to take a generic type since I have multiple identity types. 我有以下模型,由于我有多个标识类型,因此我刚刚修改了IEntity接口以采用通用类型。
public interface IEntity<T>
{
T Id { get; set; }
}
public class Product : IEntity<int>
{
public int Id { get; set; }
}
Now I have to modify my IRepository and IProductRepository to reflect this change but I am not sure how. 现在,我必须修改IRepository和IProductRepository以反映此更改,但是我不确定如何更改。
public interface IRepository<TEntity> where TEntity : IEntity
{
void Add(TEntity entity);
void Delete(TEntity entity);
}
public interface IProductRepository : IRepository<Product>
{
}
Anyone care to push me in the right direction? 有人愿意将我推向正确的方向吗?
Thanks 谢谢
You need to add a second generic parameter: 您需要添加第二个通用参数:
public interface IRepository<TEntity, TID> where TEntity : IEntity<TID>
{
void Add(TEntity entity);
void Delete(TEntity entity);
}
public interface IProductRepository : IRepository<Product, int>
