Enum Enhancements

EnumConverter allows to convert primitive types into arbitrary enum type and vice versa. It is helpful if enum type is defined as generic parameter and not known at compile time.

using DotNext;
using System;

enum Color: int
{
    Black = 0,
    Red = 0xFF0000,
    Green = 0x00FF00,
    Blue = 0x0000FF,
    White = 0xFFFFFF
}

public static E Plus<E>(E first, E second, E third) 
    where E: unmanaged, Enum
{
    var result = first.ToInt64() + second.ToInt64() + third.ToInt64();
    return result.ToEnum<E>();
}

var white = Plus(Color.Red, Color.Green, Color.Blue);
white == Color.White;   //true

Attributes

EnumType static classes exposes access to custom attributes attached to the enum member.

using DotNext.Reflection;

sealed class EnumMemberAttribute : Attribute
{
}

enum MyEnum
{
    None = 0,

    [EnumMember]
    WithAttribute = 1,
}

EnumMemberAttribute attr = MyEnum.WithAttribute.GetCustomAttribute<MyEnum, EnumMemberAttribute>();
