A C# source generator to create an enumeration class from an enum type. With this package, you can work on enums very, very fast without using reflection.

Supernova.Enum.Generators

The best Source Generator for working with enums in C#

A C# source generator to create an enumeration class from an enum type. With this package, you can work on enums very, very fast without using reflection.

Package - Supernova.Enum.Generators

Add the package to your application using

dotnet add package Supernova.Enum.Generators

Adding the package will automatically add a marker attribute, [EnumGenerator], to your project.

To use the generator, add the [EnumGenerator] attribute to an enum. For example:

[EnumGenerator]
public enum UserTypeTest
{
    [Display(Name = "مرد", Description = "Descمرد")] Men = 3,

    [Display(Name = "زن", Description = "Descزن")] Women = 4,

    //[Display(Name = "نامشخص")]
    None
}

This will generate a class called EnumNameEnumExtensions (UserTypeTest + EnumExtensions), which contains a number of helper methods. For example:

    public static class UserTypeTestEnumExtensions
    {
        public static readonly ImmutableDictionary<UnitTests.UserTypeTest, string> DisplayNamesDictionary = new Dictionary<UnitTests.UserTypeTest, string>
        {
                {UnitTests.UserTypeTest.Men, "مرد"},
                {UnitTests.UserTypeTest.Women, "زن"},
                {UnitTests.UserTypeTest.None, "None"},

        }.ToImmutableDictionary();

        public static readonly ImmutableDictionary<UnitTests.UserTypeTest, string> DisplayDescriptionsDictionary = new Dictionary<UnitTests.UserTypeTest, string>
        {
                {UnitTests.UserTypeTest.Men, "Descمرد"},
                {UnitTests.UserTypeTest.Women, "Descزن"},
                {UnitTests.UserTypeTest.None, "None"},

        }.ToImmutableDictionary();

        public static string ToStringFast(this UnitTests.UserTypeTest states, string defaultValue = null)
        {
            return states switch
            {
                UnitTests.UserTypeTest.Men => nameof(UnitTests.UserTypeTest.Men),
                UnitTests.UserTypeTest.Women => nameof(UnitTests.UserTypeTest.Women),
                UnitTests.UserTypeTest.None => nameof(UnitTests.UserTypeTest.None),
                _ => defaultValue ?? throw new ArgumentOutOfRangeException(nameof(states), states, null)
            };
        }
        public static bool IsDefinedFast(UnitTests.UserTypeTest states)
        {
            return states switch
            {
                UnitTests.UserTypeTest.Men => true,
                UnitTests.UserTypeTest.Women => true,
                UnitTests.UserTypeTest.None => true,
                _ => false
            };
        }
        public static bool IsDefinedFast(string states)
        {
            return states switch
            {
                nameof(UnitTests.UserTypeTest.Men) => true,
                nameof(UnitTests.UserTypeTest.Women) => true,
                nameof(UnitTests.UserTypeTest.None) => true,
                _ => false
            };
        }
        public static string ToDisplayFast(this UnitTests.UserTypeTest states, string defaultValue = null)
        {
            return states switch
            {
                UnitTests.UserTypeTest.Men => "مرد",
                UnitTests.UserTypeTest.Women => "زن",
                UnitTests.UserTypeTest.None => "None",
                _ => defaultValue ?? throw new ArgumentOutOfRangeException(nameof(states), states, null)
            };
        }
        public static string ToDescriptionFast(this UnitTests.UserTypeTest states, string defaultValue = null)
        {
            return states switch
            {
                UnitTests.UserTypeTest.Men => "Descمرد",
                UnitTests.UserTypeTest.Women => "Descزن",
                UnitTests.UserTypeTest.None => "None",
                _ => defaultValue ?? throw new ArgumentOutOfRangeException(nameof(states), states, null)
            };
        }
        public static UnitTests.UserTypeTest[] GetValuesFast()
        {
            return new[]
            {
                UnitTests.UserTypeTest.Men,
                UnitTests.UserTypeTest.Women,
                UnitTests.UserTypeTest.None,
            };
        }
        public static string[] GetNamesFast()
        {
            return new[]
            {
                nameof(UnitTests.UserTypeTest.Men),
                nameof(UnitTests.UserTypeTest.Women),
                nameof(UnitTests.UserTypeTest.None),
            };
        }
        public static int GetLengthFast()
        {
            return 3;

        }
    }

You do not see this file inside the project. But you can use it.

Usage

var stringEnum = UserTypeTest.Men.ToStringFast(); //Men;

var isDefined = UserTypeTestEnumExtensions.IsDefinedFast(UserType.Men); //true;

var displayEnum = UserTypeTest.Men.ToDisplayFast(); //مرد

var descriptionEnum = UserTypeTest.Men.ToDescriptionFast(); //Descمرد

var names = UserTypeTestEnumExtensions.GetNamesFast(); //string[]

var values = UserTypeTestEnumExtensions.GetValuesFast(); //UserType[]

var length = UserTypeTestEnumExtensions.GetLengthFast(); //3

If you had trouble using UserTypeTestEnumExtensions and the IDE did not recognize it. This is an IDE problem and you need to restart the IDE once.
