Serial exception even with [field: NonSerialized]

Question

I have an IPC server working with some really simple interface that is working fine now. The interface itself is very simple and consists of only 4 methods. (RemoteCall Method - SingleTone):

[Serializable]
public class NetworkHook : MarshalByRefObject
{
    public void onIsInstalled(int pid, MessageDirection direction)
    {
    }

    public void onDataRecieved(int pid, MessageDirection direction, byte[][] data)
    {
    }

    public void onException(int pid, MessageDirection direction, Exception exception)
    {
    }

    public void onPing(int pid, MessageDirection direction)
    {
    }
}

The problems started when I started adding events to this class (so that any part of the server can subscribe to incoming messages, the remote call method is SingleTone to store eventlisteners). Since NetworkHook is serializable, I started adding [field: NonSerialzied] tags to my events. This should be good, since I don't need clients to let them know about listener events (or they don’t want to be at all), so losing them is fine:

[field: NonSerialized]
public event EventHandler<InstalledEventArgs> Test;

, :

public delegate void HookInstalledEventHandler(object sender, HookInstalledEventArgs args);

[field: NonSerialized]
public event HookInstalledEventHandler Test;

- , . NetworkHook:

public virtual void GetObjectData(SerializationInfo info, StreamingContext context)
{ 

}

Answer 1

event - .

.

:

private EventHandler eventField;

public event EventHandler SomeEvent
{
  add { eventfield = Delegate.Combine(eventfield, value); }
  remove { eventfield = Delegate.Remove(eventfield, value); }
}

, NonSerialized eventField.
