如何将自定义对象的集合存储到user.config文件？

[Serializable]
public class CustomObject
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class Program
{
    public static void Main(string[] args)
    {
        // 创建自定义对象集合
        List<CustomObject> objects = new List<CustomObject>
        {
            new CustomObject { Id = 1, Name = "Object 1" },
            new CustomObject { Id = 2, Name = "Object 2" },
            new CustomObject { Id = 3, Name = "Object 3" }
        };

        // 将对象集合序列化为字节数组
        BinaryFormatter formatter = new BinaryFormatter();
        using (MemoryStream stream = new MemoryStream())
        {
            formatter.Serialize(stream, objects);
            byte[] serializedData = stream.ToArray();

            // 将序列化的数据存储到user.config文件中
            Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
            config.AppSettings.Settings["CustomObjects"].Value = Convert.ToBase64String(serializedData);
            config.Save(ConfigurationSaveMode.Modified);
            ConfigurationManager.RefreshSection("appSettings");
        }

        // 从user.config文件中读取和反序列化对象集合
        string serializedDataString = ConfigurationManager.AppSettings["CustomObjects"];
        byte[] serializedData = Convert.FromBase64String(serializedDataString);
        using (MemoryStream stream = new MemoryStream(serializedData))
        {
            List<CustomObject> deserializedObjects = formatter.Deserialize(stream) as List<CustomObject>;

            // 输出反序列化后的对象集合
            foreach (CustomObject obj in deserializedObjects)
            {
                Console.WriteLine($"Id: {obj.Id}, Name: {obj.Name}");
            }
        }
    }
}
