reciprocal link checker from ASP.NET - How do I implement one

Hi all. I cannot find on the web how I can develop a reciprocal link checker from ASP.NET.

So far what I got developed is a Screen Scraper but I want it to verify the link I request is still on the site. I am looking into verifing a bulk of sites at once and just can't seem to get the scraper to what I want it to do.

Any help will be greatly welcomed.

 

Im looking for this too ..
Can you forward me the scrrenscraper ? maybe its of my use.

 

In ASP .NET C# you can do this:
=========================
String url="http://www.yahoo.com"; //example url
WebClient client=new WebClient();
Stream stream=client.OpenRead(url);
String content=reader.ReadToEnd();
String myUrl="http://www.webcosmo.com";
bool linkExists=false;
if(content.ToLower().IndexOf(myUrl)>=0)
linkExists=true;

============================
You have inlude this:
using System.Net;


best idea will be developing a windows form which will check bunch of sites in Thread with Thread.Sleep

Hope it helps.

 

Thanks for the code, ill see how it works and update this thread.

 

Run a regex once you get the Source... Also an easy way to use WebClient is using the shared method DownloadString.

Instantiate your webclient, then dim str as string = webclientobj.downloadstring("http://www.smashingdir.com") and thats it then run a regex to traverse links, then iterate through that link collection for your link

 

Do you have a sample page written in ASP.net (vb) ?
I still aint able to get this done

 

I could write up one when I get back from Vacation Sunday night - if you remind me

 

Ok, ill wait.. thanks m8
