是什么在C＃[OUT]之间进出的区别？ [英] What's the difference between [Out] and out in C#?

问题描述

我见过这两个仰视p如果在/ Invoke的定义...有时 [OUT] 时，有时退出 ...我假设它们是相同的。

I've seen both when looking up P/Invoke definitions... sometimes [Out] is used, and sometimes out... I'm assuming they're the same.

推荐答案

他们是等同于对方时在的P / Invoke 的上下文中使用 - 见的 OutAttribute 。

They are the equivalent to each other when used in the context of P/Invoke - see OutAttribute.

您可以应用OutAttribute珍视和按引用传递引用类型输入/输出行为更改到Out-仅行为，这相当于在C＃中使用了关键字。

You can apply the OutAttribute to value and reference types passed by reference to change In/Out behavior to Out-only behavior, which is equivalent to using the out keyword in C#.
