如何显示DisplayAttribute.Description属性值？

using System;
using System.ComponentModel.DataAnnotations;

public enum MyEnum
{
    [Display(Description = "这是第一个枚举值")]
    FirstValue,

    [Display(Description = "这是第二个枚举值")]
    SecondValue
}

public class Program
{
    public static void Main(string[] args)
    {
        string description = GetDisplayDescription(MyEnum.FirstValue);
        Console.WriteLine(description); // 输出：这是第一个枚举值
    }

    public static string GetDisplayDescription(Enum value)
    {
        var displayAttribute = value.GetType()
            .GetField(value.ToString())
            .GetCustomAttributes(typeof(DisplayAttribute), false)
            .FirstOrDefault() as DisplayAttribute;

        return displayAttribute?.Description ?? value.ToString();
    }
}
