[英]Autofac generic registration
Is there a way I can accomplish something like this: 有没有办法我可以完成这样的事情:
var builder = new ContainerBuilder();
builder.Register(c => c.Resolve<DbContext>().Set<TEntity>()).As(IDbSet<TEntity>);
Sure, and there's even a pattern for that. 当然,甚至还有一种模式。 It's called the repository pattern: 这称为存储库模式:
public interface IRepository<TEntity>
{
IQueryable<TEntity> GetAll();
TEntity GetById(Guid id);
}
public class EntityFrameworkRepository<TEntity> : IEntity<TEntity>
{
private readonly DbContext context;
public EntityFrameworkRepository(DbContext context) {
this.context = context;
}
public IQueryable<TEntity> GetAll() {
return this.context.Set<TEntity>();
}
public TEntity GetById(Guid id) {
var item = this.context.Set<TEntity>().Find(id);
if (item == null) throw new KeyNotFoundException(id.ToString());
return item;
}
}
You can register it as follows: 您可以按以下方式注册:
builder.RegisterGeneric(typeof(EntityFrameworkRepository<>)).As(typeof(IRepository<>));
