The Generic EventHandler delegate

.NET 2.0 introduces a generic event handler delegate, the following example shows you how to use the new syntax.

public event EventHandler<EventArgs> RaiseCustomEvent;
   
protected virtual void OnRaiseCustomEvent(EventArgs e)
{
    EventHandler<EventArgs> handler = RaiseCustomEvent;
       
    if (handler != null)
    {
        handler(this, e);
    }
}

void HandleCustomEvent(object sender, EventArgs e)
{
    Console.WriteLine("Event Received");
}
   
public static void Main()
{
    MyClass ourClass = new MyClass();
   
    // Subscribe to event
    ourClass.RaiseCustomEvent += ourClass.HandleCustomEvent;
   
    // How to raise an event.
    ourClass.OnRaiseCustomEvent(new EventArgs());
}
