如何获得在C＃中枚举类型的全局访问？ [英] How to get global access to enum types in C#?

问题描述

这可能是一个愚蠢的问题，但我似乎无法做到这一点。我想成立一​​个类中的一些枚举是这样的：

This is probably a stupid question, but I can't seem to do it. I want to set up some enums in one class like this:

public enum Direction { north, east, south, west };

然后有那么一些其他类可以例如具有可访问到所有类，枚举类型：

Then have that enum type accessible to all classes so that some other class could for instance have:

Direction dir = north;

和能够通过阶级之间的枚举类型：

and be able to pass the enum type between classes:

public void changeDirection(Direction direction) {
   dir = direction;
}

我认为枚举设置公共将使这个自动可能的，但似乎没有被我宣布在枚举类的外部可见的。

I thought that setting the enum to public would make this automatically possible, but it doesn't seem to be visible outside of the class I declared the enum in.

推荐答案

您可以做两件事情之一。

You can do one of two things.

1 - 将枚举的声明外部类

1- Move the declaration of the enum outside of the class

今天，你可能有这样的事情。

Today you probably have something like this

public class ClassName
{
  public enum Direction
  {
    north, south, east, west
  }
  // ... Other class members etc.
}

这将改变为

public class ClassName
{      
  // ... Other class members etc.
}

// Enum declared outside of the class
public enum Direction
{
  north, south, east, west
}

2 - 使用类名

2- Reference the enum using the class name

ClassName.Direction.north

例如：

public void changeDirection(ClassName.Direction direction) { 
   dir = direction; 
}

其中，类名是你宣布在枚举类的名称。

Where ClassName is the name of the class that you declared the enum in.
