Question

I have two questions.

1) Should you always use a using statement on a connection? So, I would use it on the connection and then another one on a reader within the connection? So I would be using two using statements.

2) Lets say you use the using statement on the connection and also a reader being returned on the connection. So you have two using statements. Does it create two Try{}Finally{} blocks or just one?

Thanks!

Answer 1

1. You should always use a using statement when an object implements IDisposable. This includes connections.

2. It will create two nested try{}finally{} blocks.
