Events Invocation
<p>If a class declares a event then event can be fired only from that class. what is the reason for the restriction of the event invocation?</p>

<pre><code>using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication12
{
    delegate void Function();

    class EventHandling
    {
        public event Function fun;

        public void AddEvents(Function events)
        {
            fun += events;
        }

        public void Notify()
        {
            fun();
        }
    }

    class Program
    {

        static void Main(string[] args)
        {
            EventHandling aEvtHandler = new EventHandling();
            Function aFun = new Function(Display);
            aEvtHandler.AddEvents(aFun);
            aEvtHandler.Notify();
        }

        static void Display()
        {
            Console.WriteLine("in the display");
            Console.Read();
        }
    }
}
</code></pre>
