Check if the connection is still open...

Hello friends, I have a small problem, I need to check if the database connection is still open. Here is my code...

try {
// new connection
// connection open
// other code
// close the connection
} catch (Exception ex) {
// handling exception
} finally {
// Here I want to close the connection if still open
}
So... how to check id the connection is still open ?
p.s. I use C#.NET 2.0, MS Access database (OleDbConnection).

Thanks.
