Hello,

I am familiar with extract data from search engines like Google, etc using crawling with C#.

For example i use Regular expression, HttpRequest and HttpResponse and this is a simple example of geeting data from Google

private void GoogleSearch(string _keyword) 
    {
        HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create("http://www.google.com.eg/#q="+_keyword);

        HttpWebResponse httpRes = (HttpWebResponse)httpReq.GetResponse();

        StreamReader sr = new StreamReader(httpRes.GetResponseStream());

        string responseText = sr.ReadToEnd();

        Regex mainRegex = new Regex("<li class=" + '"' + "g" + '"' +">.*?</li>");

        MatchCollection matchs = mainRegex.Matches(responseText);

        foreach (Match m in matchs)
        {
            MessageBox.Show(m.Value);
        }
    }

Now, i need to get data from Linkedin search engine, so i should simulate the login to Linkedin before i can make the search.

so can any one help me and tell me what is the mechanism of doing this ?

Thanks
