パターン2: Description属性で画面表示

using System;
using System.ComponentModel;
using System.Reflection;
 
public enum ProductStatus
{
    [Description("販売中")]
    Active = 1,
 
    [Description("一時停止")]
    Suspended = 2,
 
    [Description("廃番")]
    Discontinued = 9
}
 
//拡張メソッドでDescriptionを取得
public static class EnumExtensions
{
    public static string GetDescription(this Enum value)
    {
        FieldInfo field = value.GetType().GetField(value.ToString());
        if (field == null)return value.ToString();
 
        var attribute = field.GetCustomAttribute<DescriptionAttribute>();
        return attribute?.Description ?? value.ToString();
    }
}
 
//使い方
class Program
{
    static void Main()
    {
        var status = ProductStatus.Active;
        string label = status.GetDescription();  // "販売中"
 
        Console.WriteLine($"ステータス: {label}");
    }
}
