简单委托与事件！

Question

using System;
using System.Collections.Generic;
using System.Text;namespace Myproject
{
    public delegate void TestEventDelegate();
    class EventSource
    {
        public event TestEventDelegate TestEvent;
        public void RaiseTestEvent()
        {
            if (TestEvent != null)
            {
                TestEvent();
            }
        }
    }
    class EventReceive
    {
        public void ReceiveTestEvent()
        {
            Console.WriteLine("事件接收");
        }
        public void Subscribe()
        {
            //怎么写  ？
 
        }
    }    class Program
    {
        
        static void Main(string[] args)
        {
            //接下来应该怎么写  ？
        }
    }
}
我定义了一个Subscribe方法，该方法如何把ReceiveTestEvent方法和TestEvent事件联系起来？同时在该方法中调用RaiseTestEvent方法。然后又是如何在Main方法中调用EventReceive类中Subscribe方法 ？

Answer 1

    class EventReceive
    {
        public void ReceiveTestEvent()
        {
            Console.WriteLine("事件接收");
        }
        public void Subscribe()
        {
            //怎么写  ？
            EventSource eventSource = new EventSource();
            eventSource.TestEvent += new TestEventDelegate(ReceiveTestEvent);            eventSource.RaiseTestEvent(); // 引发事件
        }
    } 
    class Program
    {
       
        static void Main(string[] args)
        {
            //接下来应该怎么写  ？
            EventReceive eventReceive = new EventReceive();
            eventReceive.Subscribe();
        }
    }

Answer 4

 class Program
    {
        static void Main(string[] args)
        {
            EventSource e = new EventSource();
            EventReceive er = new EventReceive();
            er.Subscribe();
            e.RaiseTestEvent();
        }
    }    public delegate void TestEventDelegate();
    class EventSource
    {
        public static event TestEventDelegate TestEvent;
        public void RaiseTestEvent()
        {
            if (TestEvent != null)
            {
                TestEvent();
            }
        }
    }
    class EventReceive
    {
        public void ReceiveTestEvent()
        {
            Console.WriteLine("事件接收");
            Console.Read();
        }
        public void Subscribe()
        {
            EventSource.TestEvent += new TestEventDelegate(ReceiveTestEvent);
        }
    } 

Answer 5

using System;
using System.Collections.Generic;
using System.Text;namespace Myproject
{
    public delegate void TestEventDelegate();
    class EventSource
    {
        public  event TestEventDelegate TestEvent;
        public void RaiseTestEvent()
        {
            if (TestEvent != null)
            {
                TestEvent();
            }
        }
    }
    class EventReceive
    {
        public void ReceiveTestEvent()
        {
            Console.WriteLine("事件接收");
        }
        public void Subscribe()
        {
            //EventSource.TestEvent += new TestEventDelegate(ReceiveTestEvent);
            EventSource eventSource = new EventSource();
            eventSource.TestEvent += new TestEventDelegate(ReceiveTestEvent);            eventSource.RaiseTestEvent(); // 引发事件 
 
        }
    }    class Program
    {
        
        static void Main(string[] args)
        {
            //EventSource e = new EventSource();
            //EventReceive er = new EventReceive();
            //er.Subscribe();
            //e.RaiseTestEvent();
            EventReceive eventReceive = new EventReceive();
            eventReceive.Subscribe(); 
        }
    }
}
综上所述...
