Examples

The following code example demonstrates how to export the department records to a JSON string using startRow, endRow, startColumn, and endColumn parameters.

using DWNet.Data;
using SnapObjects.Data;
using System;

namespace Appeon.ApiDoc.IDwDataExporterExamples
{
    public class ExportPlainExample
    {
        private readonly SchoolContext _context;

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

        public void Example9()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();

            // Get DataStore exporter in JSON format.
            var exporter = datastore.GetDataExporter(DataFormat.Json);

            // Exports records in rows 1 through 11 and in columns 2 and 3 of the primary buffer
            string json = exporter.ExportPlain(DwBuffer.Primary, 0, 10, 1, 2);

            Console.WriteLine(json);

            /*The exported JSON file is:

            ExportPlainJson9.json  
            */
        }
    }
