Question

public interface IRepository<TEntity, in TID> where TEntity : IAggregateRoot
{
    TEntity Find(TID id);
}

其实施如下：

    public class Repository<TEntity, TID> : IRepository<TEntity, TID> where TEntity : class, IAggregateRoot
{
    public virtual TEntity Find(TID id)
    {
        return _unitOfWork.Session.Get<TEntity>(id);
    }
}

如何在上面的存储库中传递 TID ？

Answer 1

这是一种通用类型。您必须在实例存储库时定义它。对于示例，对于名为Product的实体，其中Id为int。

var productRepository = new Repository<Product, int>();

// to call a method, you have to pass the TID defined, which is an int 
// and it will return a TEntity, that is a Product.
Product product = productRepository.Find(1);

如何在Generic Repository中传递实体和ID？
