哪一个更有效：列表＆LT; INT＆GT;或INT [] [英] Which one is more efficient : List<int> or int[]

问题描述

有人能告诉我哪一个是之间更高效的名单，LT; INT＆GT; 和 INT [] 。因为我工作的一个项目，正如你可能知道效率的方式如此重要的问题了。

如果您加入了一些介绍性说明到您的文章，这将会是巨大的寿：）

解决方案

 （名单应可调整大小）？清单＆LT; INT＆GT; ：INT []
 

列表＆LT; INT＆GT; 是 INT [] 根据需要调整大小的包装。随着JIT内联，他们应该执行的几乎的相同，但JIT将有一个更简单的时间挤掉从额外的性能 INT [] ，因为它是一个CLI原始专用IL指令。

Can someone tell me which one is more efficient between List<int> and int[]. Because I am working on a project and as you might know efficiency is way so important concern now.

If you added some introductory note to your post, it'd be great tho :)

解决方案

(list should be resizable) ? List<int> : int[]

List<int> is a wrapper for int[] that resizes as needed. With JIT inlining, they should perform almost identically, but the JIT will have an easier time edging out the extra performance from int[] because it's a CLI primitive with dedicated IL instructions.
