What is it?

Constant enables developers to create smart enums in C# and is implemented using .NET portable class libraries.

Basic use

Creating constants:

private class Producttype : Constant<Producttype>
{
	[DefaultKey]
	public static readonly Producttype Default = new Producttype("default", false);
	public static readonly Producttype Box = new Producttype("box", true);

	private TestableConstant(string key, bool isValid)
	{
		this.Add(key, this);
		IsValid = isValid;
	}

	public bool ValidType { get; private set; }
}

Using constants:

public class Product
{
	private Producttype producttype;
	
	public Product(string type)
	{
		producttype = ProductType.GetOrDefaultFor(type);
	}	

	public void Validate()
	{
		if(prodtuctype.IsValid)
		{
			return true;
		}

		// Just to illustrate that it can be used as a normal enum as well
		if(producttype == Producttype.Default)
		{
			return true;
		}

		return false;
	}	
}

Motivation

The project was created because I found I had needs for this in quite a few projects and got tired of moving the code around. Enums in themselves can end up hiding businesslogic so this is the logical next step. Making it to a NuGet package made using this much easier.

Installation

The project can be installed easiliy via NuGet or by downloading and compiling the source yourself.
