Autofac通用注册

Question

有没有一种方法，我可以做到这样的事：

var builder = new ContainerBuilder(); 
builder.Register(c => c.Resolve<DbContext>().Set<TEntity>()).As(IDbSet<TEntity>);

当然，甚至还有一种模式为。这就是所谓的仓库模式：

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; 
    } 
} 

可以按如下方式进行注册：

builder.RegisterGeneric(typeof(EntityFrameworkRepository<>)).As(typeof(IRepository<>));
