Question

I know how to use try/catch block in case of database calls and know how to use “using” directive in context of using try/finally construction as well.

But, can I mix them? I mean when I use “using” directive can I use try/catch construction as well because I still need to handle possible errors?

Of course you can do it:

using (var con = new SomeConnection()) {
    try {
        // do some stuff
    }
    catch (SomeException ex) {
        // error handling
    }
}

using is translated by the compiler into a try..finally, so it’s not very different from nesting a try..catch inside a try..finally.
