Make an ADO.Net connection when you have an SMO connection
When you have an SMO connection, it is very easy to make an ADO.Net connection as the connection string is exactly the same. Then you just have to reuse it.

SqlConnection mySQLConnection;
mySQLConnection =
new SqlConnection(ServerConn.ConnectionString);
mySQLConnection.Open();
