Generally, that's not a very reasonable thing to do. The thing is, you can check, and maybe the check succeeds. Then the connection dies. Then you try sending and the send fails -- you have to handle that, so the check was a waste of time.
Or you check and the check fails, but then the connection recovers.

Whether you're checking for network or database or a file or disk, it's better just to try it and see whether or not it fails. Doing otherwise is just a waste of effort, in time, in development, in testing, in maintenance.

In the case you mention, what if the connection is live, but the SMTP server isn't or refuses the connection? There are a lot more things that can go wrong than just "no connection to the Internet".

Try it, and handle any Exception that results -- you have to anyway.

i solved this problem my self. i want to see if the connection is open then send my file instead of send file and see that there is not any open connection. first way is smarter.
