拳击的优势在于你可以传递一个整数作为

对象。拆箱的好处是你可以获得原生整数性能

回来。

The advantage of boxing is that you can pass, say, an integer around as an
object. The advantage of unboxing is you get you native integer performance
back.

您可以拥有获取或返回任何类型值的方法。你怎么会实现Reflection的GetField或SetProperty方法而没有

拳击？


其次，你可以拥有数据结构它可以保存任何类型的

您需要了解的内容。

You can have methods that take or return ANY type of value. How would
you implement Reflection''s GetField or SetProperty methods without
boxing?

Secondarily, you can have data structures that can hold ANY type of
value, like an object[] or 1.x''s ArrayList and HashTable.
