I have a class, EventContainer.cs, which contains an event, say:

I have another class, EventRaiser.c

Not a good programming but if you want to do that any way you can do something like this

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

        Extension ext = new Extension();
        ext.MyEvent += ext_MyEvent;
        ext.Dosomething();
    }

    static void ext_MyEvent(int num)
    {
        Console.WriteLine(num);
    }
}


public class Extension
{
    public delegate void MyEventHandler(int num);
    public event MyEventHandler MyEvent;

    public void Dosomething()
    {
        int no = 0;
        while(true){
            if(MyEvent!=null){
                MyEvent(++no);
            }
        }
    }
}
