Question

I know that a lot of examples exist where a SqlConnection is defined and then a SqlCommand is defined, both in Using blocks:

using (var conn = new SqlConnection(connString)) {       using (var cmd = new SqlCommand()) {         cmd.Connection = conn;         //open the connection       } } 

My question: If I define the connection directly on the SqlCommand, does the connection close when the command is disposed?

using (var cmd = new SqlCommand()) {       cmd.Connection = new SqlConnection(connString);       //open the connection } 

Answer 1

No, SqlCommand never attempts to close/dispose of the connection.
