C# Better Enums Source Generator

A step in making C# enums usable in order to not fall behind Java.
A source generator that adds extension methods for enums with any attribute. Also adds more performant methods.

Install the NuGet or GitHub package.

How to use

[BetterEnum] // Add this attribute to the enum
public enum ExampleEnum {
	AnExample,
	[ExampleEnumInfo("Hello", 1)] // Add attributes to your enum members
	[Description("Another text")]
	Another,
	[Description("1")]
	One
}

The following methods are now available via an extension class:

// Faster ToString
ExampleEnum.AnExample.BetterToString();
// Access the value attributes directly
ExampleEnum.Another.GetExampleEnumInfo();
ExampleEnum.Another.GetDescription().Description;
// Programmatically access an attribute (uses slow runtime reflection on each call)
ExampleEnum.One.GetAttributeOfType<DescriptionAttribute>();

public enum ExampleEnum {
	[ExampleEnumInfo("Example Text", 123)]
	[Description("Multiple attributes")]
	Example,
	[ExampleEnumInfo("Test Enum", 5)]
	Test,
	[ExampleEnumInfo("Working enum", 7)]
	[Description("Even more attributes")]
	Working
