I have the code below to query records from a stored procedure but am concerned I may not be disposing what I need to or am disposing when the object would be cleared by the

Answer 1

You should dispose the data reader, and the command. No need to separately close the connection if you dispose the command. You should ideally do both using a using block:

using (SqlCommand cmd = new...)
{
    // do stuff
    using (SqlDataReader dr = cmd.ExecuteReader())
    {
        // do stuff
    }
}

If you need exception handling do that separately either inside or around the using blocks - no need for the finally for the Dispose calls though with using.
