Test yourself.

Just a small task for you, try not to cheat and you ll get a pie :)
Show/Hide

You have a Provider class, pretty simple:

public class Provider
{
public delegate void NotifyDelegate(string message);

public event NotifyDelegate Notify;
}

And class Consumer a bit more difficult:

public class Consumer
{
public int Id { get; set; }

~Consumer()
{
Console.WriteLine("Consumer " + Id + " finalized...");
}

public void Consumer_Notify(string message)
{
}
}

And finally here is favourable ;) static void Main:

static void Main()
{
var provider = new Provider();

var topLevelConsumers = new List();

for (var i = 0; i < 5; i++)
{
var consumer = new Consumer { Id = i };
provider.Notify += consumer.Consumer_Notify;
}

for (var i = 5; i < 10; i++)
{
var consumer = new Consumer { Id = i };
provider.Notify += consumer.Consumer_Notify;
topLevelConsumers.Add(consumer);
}

Console.WriteLine("Step 1. Collect garbage");

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();

Console.WriteLine("Step 2. Dispose provider");

provider = null;

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();

Console.WriteLine("Step 3. Close app");
Console.ReadKey();
}





Try to predict output of such main function (don't pay attention to the Id's order in output)?
