我有一个快速的问题......通过使用仿制药，做我彻底摆脱装箱/拆箱操作？

I have one quick question... by using generics, do I completely get rid of boxing/unboxing operations?

例如，通过使用清单是否仍得到很多装箱/拆箱的？

For example, by using a List do I still get lots of boxing/unboxing?

我读过一些文档在互联网上，但没能解决这个具体问题...

I've read several docs on the internet but couldn't solve this specific question...

推荐答案

如果一个类被正确写入，然后使用仿制药将避免所有的装箱和拆箱。相反，刚刚在即时编译器将产生code为每个版本的正确恰当地处理值类型的类。

If a class was written correctly, then using generics will avoid all boxing and unboxing. Instead, the just-in-time compiler will generate code for each version of the class that correctly handles the value types appropriately.
