Risparmiare risorse per gli eventi ASP.NET

Ecco come risparmiare un pò di risorse quando si scrive un evento in ASP.NET

private static readonly object EventSubmitKey = new object();

// The Submit event.
[
Category("Action"),
Description("Raised when the user clicks the button."),
EditorBrowsable(EditorBrowsableState.Always),
Browsable(true)
]

public event EventHandler Submit
{
   add
   {
      Events.AddHandler(EventSubmitKey, value);
   }

   remove
   {
      Events.RemoveHandler(EventSubmitKey, value);
   }
}

// The method that raises the Submit event.
protected virtual void OnSubmit(EventArgs e)
{
   EventHandler SubmitHandler = (EventHandler)Events[EventSubmitKey];

   if (SubmitHandler != null)
   {
      SubmitHandler(this, e);
   }
}
