events + anonymous method question

[Grofit]

Hey,

Normally when you are using events and you add a delegate you can easily unsubscribe when cleaning up the object (on a side question if you dont will it not be GCed until it is?).

// Subscribe
SomeObject.SomeEvent += SomeObject_SomeEvent;

void SomeObject_SomeEvent(object sender, EventArgs e)
{ 
   Console.WriteLine("Called Some Event"); 

   // Unsubscribe (could cast sender)
   SomeObject.SomeEvent -= SomeObject_SomeEvent;
}

However when you use anon methods (not sure if my syntax is 100% but you get the idea:

// Subscribe
SomeObject.SomeEvent += new delegate(object sender, EventArgs e)
{
   Console.WriteLine("Called Some Event");
   // How do i unsubscribe?
}

You cant seem to unsubscribe (or there is no simple way that stands out to me) so im wondering how you can remove the listener, as i basically want to have an objects event to be listened out for once then trigger something else and then stop listening...
