Enum.Ext provides a TypeSafeEnum that has a bunch of advantages compared to the normal .NET Enum value type.
For example is it possible to store additional information directly with the enum. Furthermore you are able to query an enum based on the information stored with it.
There is also a Json-Serializer implemented, so you dont have to cast from DTOs manually.

Enum.Ext can be installed using the following command via the NuGet package manager console:
PM> Install-Package Enum.Ext If you are planning to use Enum.Ext with Entity Framework Core, you should also install Enum.Ext.EFCore
https://www.nuget.org/packages/Enum.Ext.EFCore/
PM> Install-Package Enum.Ext.EFCore List of all packages that we currently offer:
PM> Install-Package Enum.Ext PM> Install-Package Enum.Ext.EFCore PM> Install-Package Enum.Ext.AutoFixture Simply inherit your class from TypeSafeEnum or TypeSafeNameEnum and adjust everything to your needs.
public sealed class Weekday : TypeSafeNameEnum<Weekday, int> { public static readonly Weekday Monday = new Weekday(1, "--Monday--"); public static readonly Weekday Tuesday = new Weekday(2, "--Tuesday--"); public static readonly Weekday Wednesday = new Weekday(3, "--Wednesday--"); .... private Weekday(int id, string name) : base(id, name) { } }use it just like the native one
var day = Weekday.Monday; // Assigns Tuesday day = (Weekday)2;and access the additional information easily
var day = Weekday.Monday; // Prints out '--Monday--' Console.WriteLine(day.Name);Just add the following line at the end of the OnModelCreating method in your DbContext class and you are ready to go
protected override void OnModelCreating(ModelBuilder modelBuilder) { ... modelBuilder.ConfigureEnumExt(); }var fixture = new Fixture(); fixture.WithEnumExt(); var weekday = fixture.Create<Weekday>();Here you find some examples how you could use the extension.
public sealed class YearlyPrice : TypeSafeEnum<YearlyPrice, int> { public decimal Price { get; private set; } public DateTime ValidFrom { get; private set; } public DateTime ValidTo { get; private set; } public static readonly YearlyPrice Price_2018 = new YearlyPrice(1, 15.99m, new DateTime(2018, 1, 1), new DateTime(2018, 12, 31)); public static readonly YearlyPrice Price_2019 = new YearlyPrice(2, 16.99m, new DateTime(2019, 1, 1), new DateTime(2019, 12, 31)); private YearlyPrice(int id, decimal price, DateTime validFrom, DateTime validTo) : base(id) { ValidFrom = validFrom; ValidTo = validTo; Price = price; } public static YearlyPrice GetPriceByDate(DateTime date) { // The List property holds all elements declared above return List.FirstOrDefault(x => x.ValidFrom <= date && date <= x.ValidTo); } }Get the according enum for a given date
DateTime date = new DateTime(2018, 5, 3); // Returns YearlyPrice.Price_2018 var price = YearlyPrice.GetPriceByDate(date);
