泛型类与非泛型类的区别有什么区别？ [英] What is the difference between generic classes and their non generic counterpart?

问题描述

这里有两个类：

    class ProductProcessor
    {
        public Product ExtendName(Product p)
        {
            p.name = p.name + " The product";
            return p;
        }
    }

    class ProductProcessor<T> where T : Product
    {
        public T ExtendName(T p)
        {
            p.name = p.name + " The product";
            return p;
        }
    }

如果两个类都没有性能损失，那么泛型类的优势是什么？

what is the advantage of the generic class given that both classes have no performance penalties?

通用存储库就是这样一种用法。

The generic Repository would be such a usage.
