C# 實時監聽值的變化

代碼：

using System;
namespace Test_Tools
{

    class Program 
    {
        static void Main(string[] args)
        {

            MonitorValueChange change = new MonitorValueChange();
            change.MyValue = 10;
            change.OnMyValueChanged += Change_OnMyValueChanged;
            change.MyValue = 10;

           
        }
        public static void Change_OnMyValueChanged(object sender, EventArgs e)
        {
            Console.WriteLine("&^%&%^&%^");
            //要做的操作
        }
    }
    public class MonitorValueChange
    {
        private int myValue;
        public int MyValue
        {
            get { return myValue; }
            set
            {
                if (value != myValue)
                {
                    WhenMyValueChange();
                }
                myValue = value;
            }
        }
        //定義的委托
        public delegate void MyValueChanged(object sender, EventArgs e);
        //與委托相關聯的事件
        public event MyValueChanged OnMyValueChanged;
        //事件觸發函數
        private void WhenMyValueChange()
        {
            if (OnMyValueChanged != null)
            {
                OnMyValueChanged(this, null);

            }
        }

    }
