To close or not to close connection in database

Question

I work with Windows-Mobile and Windows-CE using SqlCE and I dont know what better to do.

To open connection when the program open, run any

Answer 1

There are already some conflicting answers here.

To be honest, I'm not enirely sure how WinCE deals with connections. I don't think there is a ConnectionPool.

But the general pattern in .NET is to keep connections open as short as possible. This improves reliability and prevents resource leaks. Make sure you know about the using (var conn = ...) { ... } pattern.

So I would say: go with your second option, and only keep connections longer if you really experience a performance problem, and if opening the connection is the cause. I don't think it will be with SqlCE
