Examples

The following code example demonstrates how to use the DwMeta property.

using DWNet.Data;
using System;

namespace Appeon.ApiDoc.IDataStoreBaseExamples
{
    public class DwMetaExample
    {
        private readonly SchoolContext _context;

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

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

            // Gets the type of model corresponding to the current DwMeta.
            var type = datastore.DwMeta.ModelType;
            Console.WriteLine("ModelType Name: {0}", type.Name);
            Console.WriteLine("ModelType FullName: {0}", type.FullName);

            // Gets datastore columns.
            var columns = datastore.DwMeta.Columns;
            Console.WriteLine("Column Count: {0}", columns.Count);
            foreach (var item in columns)
            {
                Console.WriteLine("Column ID: {0}, Column Name: {1}", item.ID, item.Name);
            }

            // Gets DataWindow data.
            Console.WriteLine("DataWindow Processing: {0}", datastore.DwMeta.DataWindow.Processing);
            Console.WriteLine("DataWindow UpdateTable: {0}", datastore.DwMeta.DataWindow.Table.UpdateTable);
            Console.WriteLine("DataWindow UpdateWhere: {0}", datastore.DwMeta.DataWindow.Table.UpdateWhere);

            /*This code produces the following output:
