Unsuscribing not valid remote event clients

Is there any way I can remove the link or unsuscribe not valid clients?
I have a try catch in the event invocation on the server, if the server can
not raise the event, will log its fail, but i dont want the server to try
again with the same invalid client.

As Ken had suggested for another author: Please read the following
article regarding remoting and events:

http://www.dotnetjunkies.com/Tutorial/BFB598D4-0CC8-4392-893D-30252E2...

Here's a very simple example you would place into you're event handler:

if (_OnEvent!=null)
{

System.Delegate[] oClientList;


lock (OnEvenSyncObject) // a generic object to prevent additions to
the chain while we're looping
{
oClientList = _OnEvent.GetInvocationList();
}


for (int iLcv=0;iLcv<oClientList.Length;iLcv++)
{
EventDelegate del = (EventDelegate) oClientList[iLcv];
try
{
// Try to invoke the delegate -- remove from list if it fails
del();
}
catch (Exception)
{
oClientList -= del;
}
} // End chained event enum
}
