C# 和类中的嵌套枚举

发布于 2024-12-11 21:25:53 字数 159 浏览 0 评论 0原文

我听说 C# 中不可能嵌套 enum 。那么如何将以下结构转换为类层次结构或其他结构。所以我希望该类充当 enum

嵌套类和 const 字段

class Cat1
{
    public const int Public = 1;
    public class Private
    {
        public const int Abc = 2;
        public const int Mno = 3;
        public const int Pqr = 4;
    }
}

nested classes and const fields

class Cat1
{
    public const int Public = 1;
    public class Private
    {
        public const int Abc = 2;
        public const int Mno = 3;
        public const int Pqr = 4;
    }
}

public class Cat1
{
  public enum Publicpart
  {
     Xyz
  }

  private enum Privatepart
  {
     Abc, Mno, Pqr
  }
}

那么你可以这样称呼它

Cat1.Publicpart.Xyz

，或者如果你有私人访问权限

Cat1.Privatepart.Abc

public class Cat1
{
  public enum Publicpart
  {
     Xyz
  }

  private enum Privatepart
  {
     Abc, Mno, Pqr
  }
}

then you can call it like this

Cat1.Publicpart.Xyz

or if you have private acces

Cat1.Privatepart.Abc

您可以使用hirerchy作为类结构，每个类都有自己的枚举属性

如果您想通过枚举解决此问题，您应该重新考虑，因为第一个枚举类别对我来说代表某种“可见性”概念，而第二个类别仅对具有“公共”可见性的实例有效。

用这样的方法解决你的问题怎么样：

public enum Visibility
{
    Public,
    Private
}

public abstract class VisibilityState
{
    public Visibility Visibility { get; private set; }

    protected VisibilityState(Visibility visibility)
    {
        Visibility = visibility;
    }
}

public class PublicVisibilityState : VisibilityState
{
    public PublicVisibilityState() : base(Visibility.Public) { }
}

public class PrivateVisibilityState : VisibilityState
{
    public PrivateVisibilityState() : base(Visibility.Private) { }
    public OtherEnum OtherEnumState { get; set; }
}

public enum OtherEnum
{
    Abc, Mno, Pqr
}

You should rethink if you want to solve this problems via enums because the first enum category represents to me some kind of "visibility" concept while the second category is only valid of instances with visibility "public".

What about solving your issue with something like this:

public enum Visibility
{
    Public,
    Private
}

public abstract class VisibilityState
{
    public Visibility Visibility { get; private set; }

    protected VisibilityState(Visibility visibility)
    {
        Visibility = visibility;
    }
}

public class PublicVisibilityState : VisibilityState
{
    public PublicVisibilityState() : base(Visibility.Public) { }
}

public class PrivateVisibilityState : VisibilityState
{
    public PrivateVisibilityState() : base(Visibility.Private) { }
    public OtherEnum OtherEnumState { get; set; }
}

public enum OtherEnum
{
    Abc, Mno, Pqr
}
