        public static void Run()
        {

            Workbook workbook = new Workbook();

            try
            {
                // Access the collection of external connections
                ExternalConnectionCollection connections = workbook.DataConnections;

                // Find the first DBConnection in the collection (if any)
                DBConnection dbConn = null;
                foreach (ExternalConnection conn in connections)
                {
                    if (conn is DBConnection dbConnection)
                    {
                        dbConn = dbConnection;
                        break;
                    }
                }

                if (dbConn == null)
                {
                    Console.WriteLine("No DBConnection objects found in the workbook.");
                }
                else
                {
                    // Display the current Command value (read operation)
                    Console.WriteLine("Current Command: " + dbConn.Command);

                    // Demonstrate setting the Command (read-write property)
                    dbConn.Command = "SELECT * FROM Customers";
                    Console.WriteLine("Updated Command: " + dbConn.Command);
                }

                // Save the workbook
                workbook.Save("CommandDemo.xlsx");
                Console.WriteLine("Workbook saved as CommandDemo.xlsx");
            }
            catch (Exception ex)
