在C#中表示参数化枚举的最佳方法？

public class EnumDescription<T> where T : Enum
{
    public string GetDescription(T value)
    {
        var fieldInfo = value.GetType().GetField(value.ToString());
        var attributes = (DescriptionAttribute[])fieldInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
        return attributes.Length > 0 ? attributes[0].Description : value.ToString();
    }
}

public enum Color
{
    [Description("红色")]
    Red,
    [Description("绿色")]
    Green,
    [Description("蓝色")]
    Blue
}

var color = Color.Red;
var description = new EnumDescription<Color>().GetDescription(color);
Console.WriteLine(description); // 输出：红色
