Examples

The following code example demonstrates how to use the CopyTo method to copy all rows from the primary buffer of the DataStore to the departments array.

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

namespace Appeon.ApiDoc.IDataStore_GenericExamples
{
    public class CopyToExample
    {
        private readonly SchoolContext _context;

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

        public void Example()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore<D_Department>(_context);

            // This datastore has 4 records
            datastore.Retrieve();

            var departments = new D_Department[5];

            // Creates a D_Department object and populates it with data.
            var department = new D_Department
            {
                Departmentid = 20,
                Name = "New Department",
                Budget = 20,
                Startdate = DateTime.Now,
                Administrator = 2
            };

            // Sets the first element of the departments array.
            departments[0] = department;

            // Copies 4 records to the departments array. 
            // It starts at the index 1 of the array, so the first element (index = 0) 
            // in the departments array will not be affected.
            datastore.CopyTo(departments, 1);
           
            foreach( var d in departments)
            { 
                Console.WriteLine("Department Name: {0}", d.Name);
            }

            /*This code produces the following output:
            
            Department Name: New Department
            Department Name: Engineering
            Department Name: English
            Department Name: Economics
            Department Name: Mathematics    
            */
        }
    }
}
