Examples

The following code example demonstrates how to use the AddRow method to add a row of data to the DataStore.

using Appeon.ApiDoc.Models;
using DWNet.Data;
using System;
using System.Collections.Generic;

namespace Appeon.ApiDoc.IDataStoreExamples
{
    public class AddRowExample
    {
        private readonly SchoolContext _context;

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

        public void Example2()
        {
            // Instantiates a DataStore object with dataobject: d_department.
            var datastore = new DataStore("d_department", _context);

            Console.WriteLine("Before AddRow, Rowcount: {0}", datastore.Retrieve());

            // Creates a D_Department object.
            var department = new D_Department
            {
                Departmentid = 20,
                Name = "department name2",
                Budget = 20,
                Startdate = DateTime.Now,
                Administrator = 2
            };

            // AddRow method returns the zero-based index number of the row that 
            // was added.
            int currentRow = datastore.AddRow(department);

            Console.WriteLine("AddRow return value: {0}", currentRow);

            // Commits changes to database
            datastore.Update();

            Console.WriteLine("After Update and Retrieve, Rowcount: {0}",
                datastore.Retrieve());

            /*This code produces the following output:
            
            Before AddRow, Rowcount: 4
            AddRow return value: 4
            After Update and Retrieve, Rowcount: 5           
            */
        }
    }
}
