C# attribute that allows string representation of enum members & an extension method to get that string representation from an enum member.

EnumLabel.cs

public class EnumLabelAttribute : Attribute
{
	public string Label { get; private set; }
	public EnumLabelAttribute(string label) { Label = label; }
}

public static class EnumLabelExtension
{
	public static string GetLabel(this Enum @enum)
	{
		string value = null;
		var fieldInfo = @enum.GetType().GetField(@enum.ToString());
		var attrs = fieldInfo.GetCustomAttributes(typeof(EnumLabelAttribute), false) as EnumLabelAttribute[];
		if (attrs != null) value = attrs.Length > 0 ? attrs[0].Label : null;
		return value;
	}
}
// ============================================================================================
// sample usage
public enum Sample
{
        [EnumLabel("Hello World!")]
        HelloWorld = 1,
        [EnumLabel("Foo to the bar")]
        FooBar = 2
}

var label = Sample.FooBar.GetLabel(); // label is assigned the value "Foo to the bar"
