Hi all,

My project is multi-Thread service using SqlConnection (sql server + C#), stability and performance are very importance, and there are not too much connection at same time.

In fact, I does has not much experiences of working with TSQL, now I am considering 2 solution of working with SqlConnection:

- Solution1: Using (SqlConnection con = new SqlConnection(someConnectionString)){...} => so dispose() the SqlConnection each time we use.

- Solution2: Using SortedList<ThreadName, SqlConnection> to manage SqlConnection, each Thread using its own 1 SqlConnection, it was opened 1 time and wasn't dispose(), so still keep Number of Connection opening at same time is small enough, because we keep Number of Thread at same time is smaller than a threshold.

I have no idea which solution is better (good stability and performance).

Could you give me some guide.

Thank in Advance,
TuanNM

Based on the info you provided, I'd first try to keep things as simple as possible. So creating the connection and closing it when it's not needed anymore would be my choice. One reason is that the connection pooling helps you with the performance regarding to open the connection.

More info, see:
