        public ExportPlainJsonExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example5()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            // Generates data in the primary/delete/filter buffers for this example.
            datastore.Retrieve();
            datastore.DeleteRow(0);
            datastore.SetFilter("departmentid < 5");
            datastore.Filter();

            // Exports data from the primary buffer.
            string json = datastore.ExportPlainJson(DwBuffer.Primary);

            Console.WriteLine(json);

            /*The exported JSON file is:
