how i can send byte[] to other pc

The easiest way is to use Sockets: since the Socket.Send[^] method is designed to send a byte array, it seems the best to use.

There is an example on MSDN[^] of how to use.

There is no "send bytes" per se, you need to make service part, ideally, a Windows Service.

Let me list your options, low-level to high level:

Sockets. Use the class System.Net.Sockets.Socket.

TCP. Use the classes System.Net.Sockets.TcpListener in server side, System.Net.Sockets.TcpClient of client side. I would say, this is better option.

Remoting or WCF. See overview and technology samples in MSDN.

Best way to find a sample is a search in CodeProject articles, next one is Google. I used to see a number of really nice simple samples. For the classes listed above, there are nice Microsoft samples in the help or MSDN pages on those classes. This is the reason why using these classes is the easiest from the standpoint of search effort — almost no search. Remoting or WCF will require a lot more search, but the code can be very compact. Using these technologies without understanding can give very inadequate results.

I really think you don't have a good justification to make other people to do the search for you; CodeProject help is normally based on the effort done by the Inquirer.

Hi ther,

I wrote a class library and article a little while ago to do just the same thing. While I used it for a network game, it can actaully be used for any program. Have a look at:
Fast Networking Library 2

It uses Sockets to communicate with protocol Tcp. If you don't understand all of it you could also have a look at my riginal article:
Network gaming classes and functions


Hope this helps,

Ed :)
