使用结构作为高级枚举类型，并尝试按索引访问属性

public enum MyEnum
{
    Member1,
    Member2,
    Member3
}

public struct MyStruct
{
    public string Name;
    public int Value;
}

public static class MyEnumExtensions
{
    public static MyStruct GetStruct(this MyEnum myEnum)
    {
        switch (myEnum)
        {
            case MyEnum.Member1:
                return new MyStruct { Name = "Member 1", Value = 1 };
            case MyEnum.Member2:
                return new MyStruct { Name = "Member 2", Value = 2 };
            case MyEnum.Member3:
                return new MyStruct { Name = "Member 3", Value = 3 };
            default:
                throw new ArgumentOutOfRangeException(nameof(myEnum), myEnum, null);
        }
    }
}

MyEnum myEnum = MyEnum.Member2;
MyStruct myStruct = myEnum.GetStruct();

Console.WriteLine($"Name: {myStruct.Name}, Value: {myStruct.Value}");

Name: Member 2, Value: 2
