是否有使用static_cast< int>每时每刻？ [英] Is there an alternative to using static_cast<int> all the time?

问题描述

我有一个名为 StackID 的枚举，在我的代码中，我必须 static_cast c> int 相当多 - 例如

I have an enumeration called StackID, and throughout my code I have to static_cast it to int quite a bit - e.g.

StackID somestack;
int id = static_cast<int>(somestack);

有一个简单的替代方法吗？我听说过隐性转换 - 这是我可以在这里使用吗？

Is there a shorthand alternative to doing this cast over and over again ? I have heard of "implicit" conversions - is that something I can use here?

（可能与此问题）

推荐答案

是否有应该使用的东西？可能不会。如果你正在做枚举转换为int我会问，如果你正确使用枚举（或者如果你必须与一个遗留的API接口）。据说你不 static_cast枚举到ints。

Is there something you should use instead? Probably not. If you're doing enum casts to int I would question if you're using enums properly (or if you're having to interface with a legacy API.) That being said you don't have to static_cast enums to ints. That'll happen naturally.

查看这篇文章从MSN on枚举和enum-> int和int->枚举（你必须使用static_cast。）

See this article from MSN on enums and enum->int and int->enum (where you do have to use a static_cast.)
