Writing HTML Helpers

Writing HTML Helpers
page 330,
book Professional ASP.NET MVC 3

For example in: \MvcApplication1\MvcApplication1\Core\Extensions.cs write something like:

using System;
using System.IO;
using System.Web.Mvc;

namespace MvcApplication1.Core
{
    public static class HtmlExtensions
    {
        private class Extensions : IDisposable
        {
            private readonly TextWriter _writer;

            public Extensions(TextWriter writer)
            {
                _writer = writer;
            }

            public void Dispose()
            {
                _writer.Write("</table>");
            }
        } //private class Extensions : IDisposable

        //note that this part is not under private class Extensions : IDisposable
        public static IDisposable Begin(this HtmlHelper html)
        {
            var writer = html.ViewContext.Writer;
            writer.Write("<table>");
            return new Extensions(writer);
        }
    }
}

And in: \MvcApplication1\MvcApplication1\Views\Stanko\Index.cshtml Something like:

@using (Html.Begin())
{
}

after starting app in the HTML source I will see tag <table></table> from here
