I am developing a website to crawl the other website content in ASP.NET . I am able to get the content correctly but how can I identify which language is used based on that content.

I used following code.

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(TextBox1.Text ); request.UserAgent = "A .NET Web Crawler";

    WebResponse response = request.GetResponse();

    Stream stream = response.GetResponseStream();

    StreamReader reader = new StreamReader(stream);
    string htmlText = reader.ReadToEnd();
