Examples

The following code example adds an IEnumerable<IModelEntry<TModel>> objectas an element to the IDataPacker object.

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

    public class AddModelEntriesExample
    {
        private readonly SchoolContext _context;

        public AddModelEntriesExample(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);

            dataStore.Retrieve();

            var dataPacker = new DataPacker();

            // Adds the DataStore object as an element to the current IDataPacker
            // and adds the DataStore name as the key name for the element
            // and uses the DataWindow format.
            var key = nameof(dataStore);
            dataPacker.AddDataStore(key, dataStore, true);

            // Gets an `IEnumerable<IModelEntry<TModel>>` object as an element to the 
            // `IDataPacker` object.
            var entries = dataPacker.GetModelEntries<D_Department>(key);

            Console.WriteLine("GetModelEntries Count: {0}", entries.Count());

            var newPacker = new DataPacker();
            newPacker.AddModelEntries(key, entries);

            // Gets all of the data in IDataPacker and shows the data in JSON format.
            string text = newPacker.GetTextString(DataFormat.Json);
            Console.WriteLine(text);
