[Mono-devel-list] SocketException vs. RemotingException

[Casper Hornstrup]

Hi.

When attempting to instanciate a remoting object which is not
available (i.e. no service is listening on the port), .NET 1.1
throws a SocketException while Mono 1.1 throws a RemotingException.


internal static bool IsResynchronizationEnabled()
{
	BaseRemoteIntegrationObject integrationObject = (BaseRemoteIntegrationObject)
		Activator.GetObject(typeof(BaseRemoteIntegrationObject),
		                    IntegrationManagerAccess.IntegrationManagerRemotingUrl);
	return integrationObject.IsResynchronizationEnabled();
}


private bool IsResynchronizationEnabled()
{
	try
	{
		return Global.IsResynchronizationEnabled();
	}
	catch (SocketException) /* .NET */
	{
		return false;
	}
	catch (System.Runtime.Remoting.RemotingException) /* Mono */
	{
		return false;
	}
}
