        {
            Application dtsApplication = new Application();
            ConnectionInfos connectionInfos = dtsApplication.ConnectionInfos;

            // Search for the File connection in the collection
            if (connectionInfos.Contains("DTS Connection Manager for Files"))
                Console.WriteLine("The collection contains the FILE connection");
            else
                Console.WriteLine("The collection does not contain the FILE connection");
            Console.WriteLine();
