识别QuickFix是使用主要还是辅助主机进行连接

Question

I am making use of QuickFix/N

With an initiator/Client app does anyone know if there is a way to identify if the quickfix app is using Primary Host SocketConnectHost=xxx and SocketConnectPort=yyyy or Alternative/Backup/Secondary Host ie SocketConnectHost1=rrr and SocketConnectPort=zzz to connect to the server/acceptor.

Looking at the QuickFix Config tutorial i dont see anything that lets me find out.

There is no API for that, but the information is known inside QuickFIX/N. It does log it, here: https://github.com/connamara/quickfixn/blob/master/QuickFIXn/Transport/SocketInitiator.cs#L226

If you want to dig this information out, you can either modify QuickFIX/N to make some private things public (look for socketEndPoint ), or implement a logger which captures the relevant phrase, or do some system-level introspection, ie use a system API to ask "What TCP connections do I have open now," like this: Get all TCP-connections opened by application using C#
