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")]
    Men,

    [Display(Name = "زن")]
    Women,

    //[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 string ToStringFast(this UnitTests.UserTypeTest states)
        {
            return states switch
            {
                UnitTests.UserTypeTest.Men => nameof(UnitTests.UserTypeTest.Men),
                UnitTests.UserTypeTest.Women => nameof(UnitTests.UserTypeTest.Women),
                UnitTests.UserTypeTest.None => nameof(UnitTests.UserTypeTest.None),
                _ => 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,
                _ => throw new ArgumentOutOfRangeException(nameof(states), states, null)
            };
        }
        public static bool IsDefinedFast(string states)
        {
            return states switch
            {
                nameof(UnitTests.UserTypeTest.Men) => true,
                nameof(UnitTests.UserTypeTest.Women) => true,
                nameof(UnitTests.UserTypeTest.None) => true,
                _ => throw new ArgumentOutOfRangeException(nameof(states), states, null)
            };
        }
        public static string ToDisplayFast(this UnitTests.UserTypeTest states)
        {
            return states switch
            {
                UnitTests.UserTypeTest.Men => "مرد",
                UnitTests.UserTypeTest.Women => "زن",
                UnitTests.UserTypeTest.None => "None",
                _ => 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 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.
