Is it possible to add custom properties to c# enum object?

Question

Using c# Is it possible using to associate properties for each enum items?

I have used the Description Attribute to add English description to an enum item.

You can decorate elements with custom Attributes. Those can contain nearly anything you want.

[AttributeUsage(AttributeTargets.Field, AllowMultiple = false, Inherited = true)]
public class DescriptorAttribute : Attribute
{
    public bool IsFirst { get; }
    public int UnitType { get; }

    public DescriptorAttribute(bool isFirst, int unitType)
    {
        IsFirst = isFirst;
        UnitType = unitType;
    }
}

You would use this as follows:

public enum Test
{
    [Descriptor(isFirst: true, unitType: 2)]
    Element
}

you already have the code to read this attribute in your question.
