Hi, Just Ping the server from code, and check the results, if you got response your connection is not broken, else you have disconnected. Check this links to know more.

Don't. Assume it is connected. Just perform your network I/O according to your application-layer protocol, that is, send and receive data, and, if it fails, handle the exception. For more detail on that, please see my past answers:

Multple clients from same port Number[^].

By the way, please don't tell me that you don't have such application-level protocol. It would simply mean that you have it implicitly, somehow assuming what is should do. But it's always better to realize it and develop a comprehensive definition of your protocol. Please see: Application layer — Wikipedia, the free encyclopedia[^].
