在抽象字典中使用Enum Bastetype作为Key

Question

First I want to say that I am quite new to C# sharp. Is there any way implement a construct like the following? Or is there any other way to archive this?

public interface IClass 
{ 
    Dictionary<Enum, ISecondClass> { get; } 
}

public abstract class ClassBase : IClass
{
    public abstract Dictionary<Enum, ISecondClass> { get; protected set;}
}

public class ConcreteClass : ClassBase
{
    public override Dictionary<ConreteEnum, ISecondClass> { get; protected set;}
}

EDIT: I forgot to say that the concrete instance of the Dictionary needs to implement a custom Enum-comparer that need a concrete enum to get initialized

For all who are interested in the custom enum-comparer, which is needed in this case, take a look at this link: Custom-Enum-Comparer

Answer 1

You can add a generic type argument to the class/interface level

public interface IClass<TEnum>
{ 
    Dictionary<TEnum, ISecondClass> { get; } 
}

public abstract class ClassBase<TEnum> : IClass<TEnum>
{
    public abstract Dictionary<TEnum, ISecondClass> { get; protected set;}
}

public class ConcreteClass : ClassBase<ConcreteEnum>
{
    public override Dictionary<ConcreteEnum, ISecondClass> { get; protected set;}
}
