  You WebClient, which will help to download the html

  protected void Page_Load(object sender, EventArgs e)
          {
              using (WebClient client = new WebClient())
              {
                  client.DownloadStringCompleted += client_DownloadStringCompleted;
                  client.DownloadStringAsync(new Uri("Your url"));
              }
          }
  
          void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
          {
              string html = e.Result;
          }

  Thanks & Regards,

  Hi Bimal,

  Its throwing an exception 

  "Asynchronous operations are not allowed in this context. Page starting an asynchronous operation has to have the Async attribute set to true and an asynchronous operation can only be started on a page prior to PreRenderComplete event."

  Two ways

  1. Include Async="true" with Page directive like

  <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
      CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" Async="true" %>

   or

      2. Use sync method call like

  string html = null;
              using (WebClient client = new WebClient())
              {
                  html = client.DownloadString(new Uri("Your url"));
              }

  Thanks & Regards,
  Bimal

  Hi,

  The WebClient class provides some common methods for sending data to and receiving data from a resource identified by a URL.

  As you description and replies above, you just need to retrieve data from one URL， please check this reference below about WebClient which shows several methods to retrieve data from URL

  The following table describes WebClient methods for downloading data from a resource.

  <div style="text-align: left; widows: 2; text-transform: none; text-indent: 0px; letter-spacing: normal; font: bold 13px 'Segoe UI', Verdana, Arial; white-space: normal; orphans: 2; height: 20px !important; color: #3f529c; clear: both !important; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" class="caption" xmlns="http://www.w3.org/1999/xhtml"></div> <div style="text-align: left; widows: 2; text-transform: none; text-indent: 0px; letter-spacing: normal; font: 13px 'Segoe UI', Verdana, Arial; white-space: normal; orphans: 2; color: #000000; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" class="tableSection" xmlns="http://www.w3.org/1999/xhtml">

  Method	Description
  OpenRead	Returns the data from a resource as a Stream.
  OpenReadAsync	Returns the data from a resource, without blocking the calling thread.
  DownloadData	Downloads data from a resource and returns a Byte array.
  DownloadDataAsync	Downloads data from a resource and returns a Byte array, without blocking the calling thread.
  DownloadFile	Downloads data from a resource to a local file.
  DownloadFileAsync	Downloads data from a resource to a local file, without blocking the calling thread.
  DownloadString	Downloads a String from a resource and returns a String.
  DownloadStringAsync	Downloads a String from a resource, without blocking the calling thread.

  </div>

   

  Apart from using WebClient, you also can try using HmtlAgilityPack which is a html parser/crawler

  Hi

  To read the whole page:

  string thewholepage = HttpContent( url );

  private string HttpContent( string url )
  {
  	WebRequest objRequest= System.Net.HttpWebRequest.Create(url);
  	StreamReader sr =  new StreamReader( objRequest.GetResponse().GetResponseStream() );  
  	string result = sr.ReadToEnd();
  	sr.Close();
  	return result;
  }
