Question

If I do not care about a thrown Exception. Can I code in a way as not to create it?

In other words, can an Exception be thrown but no Exception object be created?

An example – Simple example using a System.Net.Sockets.Socket

 Socket acceptingSocket;
acceptingSocket.Blocking = false;

while(condition)
{
    try
    {
        Socket acceptedSocket = acceptingSocket.Accept(); //(i)
        doWork(acceptedSocket);
    }
    catch{}
}

because the socket is in non-blocking mode
if there is no connection to accept
a SocketException is thrown at point (i)
and the conditional loop continues.

using this code implementation – will the SocketException object be created?

AND if it is created – is there a way to NOT create it?

Answer 1

You can’t suppress exceptions, you can only ignore them. In any case, it’s not the creating of the Exception object that’s expensive — it’s the stack walk that happens when the exception is thrown.

Also,

catch(SocketException) {}

not

catch { } or catch(Exception) { }
