Best practice? open and close multi connections, or one large open connection for ado.net

Question

I am using ADO.Net for some database connectivity and I was just hoping I was doing it the right way. I am opening and closing multiple connections for each stored procedur

Answer 1

A better way to do this would be to prep both of the commands and then open the connection and execute them both in quick succession:

conn.Open();
comm1.ExecuteReader();
comm2.ExecuteReader();

Always keep them open for as short a time as possible.
