WPF，这个更改通知怎么写

Question

在使用类里写,比如.
using System;
using System.ComponentModel;namespace CSCnsl {
    class Person : INotifyPropertyChanged {
        private string name;
        public string Name {
            get { return name; }
            set { name = value; OnPropertyChanged("Name"); }
        }  public event PropertyChangedEventHandler PropertyChanged;
        protected void OnPropertyChanged(string propertyName) {
            if (PropertyChanged != null) {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
    class Program {
        static void Main(string[] args) {
            Person p = new Person();
            p.PropertyChanged += p_PropertyChanged;
            p.Name = "改下名字";
         
        }        static void p_PropertyChanged(object sender, PropertyChangedEventArgs e) {
            Console.WriteLine("在我这里写具体的操作");
        }
    }
}

Answer 1

class Program
    {
        static void Main(string[] args)
        {
            Person person = new Person();
            person.PropertyChanged += Message;
            person.Name = "Name";
        }        //名字改变后的逻辑写在这个方法里
        private static void Message(object sender, PropertyChangedEventArgs e)
        {
            Console.WriteLine("Name Changed: " + e.Name);
            Console.Read();
        }
    }    public class Person : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;        private string name;
        public string Name
        {
            get { return name; }
            set
            {
                name = value;
                if (name != string.Empty)
                    OnPropertyChanged(name);
            }
        }        protected void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
