Answer 1

Yes, you will have to dispose (of) the connection separately. You can also see this in the source code: SqlCommand.Dispose() does not close or dispose the connection it uses (by the way, that would be bad anyway as you could not execute multiple commands with the same connection).

Answer 2

yes , it is necessary to dispose the sqlconnection and sqlcommand object after your piece of code gets executed.

Now, there are two ways by which you can achieve this:

1. Write your code in using statement which will take care of disposing the objects, as sqlconnection and sqlcommand implements the IDisposable interface which takes care of disposing the objects..
2. by calling .close() method explicitly on sqlconnection object.
