When I have a return within the code of Using(connection) does the connection and db objects gets dismissed properly

Question

I'm not sure if my question is clear so here's a code sample:

    public static bool isRecordExist(int ID)
    {
        using (SqlConnection connection = new SqlConnection(ConnectionString))
        {
            using (SqlCommand command = new SqlCommand(commandText, connection))
            {
                int flag = int.Parse(command.ExecuteScalar);

                if (flag)
                    return false;
                else
                    return true;
            }
        }
    }

So, now I understand that I don't need to close or dismiss any Sql objects when I have the 'using' keyword, because it does that automatically as soon as you get our of it's brackets but now the we reach to the 'return' part. will it dismiss and close the objects properly or do I need to save this value and make my check and 'return' outside the 'using' code ?

Answer 1

Yes it closes automatically. Exiting a using block calls .Dispose() on the object in question which for a SqlConnection will close the connection and any open resources.

Does End Using close an open SQL Connection
