Examples

The following code example demonstrates how to export the department records in the first and the second rows in the primary buffer to an XML string.

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

namespace Appeon.ApiDoc.DataStoreDataExtensionsExamples
{
    public class ExportXmlExample
    {
        private readonly SchoolContext _context;

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

        public void Example7()
        {
            // Instantiates the datastore with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();

            // Exports data from the first and second rows of the primary buffer.
            string xml = datastore.ExportXml(DwBuffer.Primary, 0, 1, MappingMethod.Index);

            Console.WriteLine(xml);

            /*The exported XML file is:

            ExportXml7.xml  
            */
        }
    }
}
