[Flags] 属性到底有什么作用? [英] What Does the [Flags] Attribute Really Do?

问题描述

应用 [Flags] 真的吗?

What does applying [Flags] really do?

我知道它修改了 Enum.ToString，但它还有别的作用吗?(例如，不同的编译器或运行时行为等)

I know it modifies the behavior of Enum.ToString, but does it do anything else? (e.g. Different compiler or runtime behavior, etc.)

编辑:是的，我知道它记录一个事实，即枚举旨在用作按位标志，并且应用它更合乎逻辑位标志.不过，我更多的是询问具体的行为变化，而不是一般的编程实践.

Edit: Yeah, I'm aware that it documents the fact that the enum is intended to be used as bitwise flags, and that it's more logical to apply it to bit flags. I was asking more about concrete behavior changes though, not general programming practices.

推荐答案

来自 MSDN 文章:

有趣的是，当Flags 被指定，Parse 和 Format方法具有高级功能.

It is interesting to note that when Flags is specified, Parse and Format methods feature advanced capabilities.

同样，Parse 方法可以成功解析逗号分隔像刚才显示的那样的字符串正确的数值.

Likewise, the Parse method can successfully parse a comma-separated string like the one just shown into the proper numeric value.
