如何从[Serializable] INotifyPropertyChanged实现者中排除不可序列化的观察者？

using System;
using System.ComponentModel;
using System.Runtime.Serialization;

namespace SerializationExample
{
    [Serializable]
    public class SerializableClass : INotifyPropertyChanged
    {
        [field: NonSerialized]
        public event PropertyChangedEventHandler PropertyChangedEx;

        private string _name;

        public string Name
        {
            get { return _name; }
            set
            {
                _name = value;
                OnPropertyChanged(nameof(Name));
            }
        }

        protected virtual void OnPropertyChanged(string propertyName)
        {
            PropertyChangedEx?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}
