C# translator with babel fish translator

I need a translation in my C# code, babel fish translator. So far I have this code..but I always get the "error" string, something wrong with the regex part, can anyone help me with this one plz ?? thanks alot

PS: IF there's any other way of coding will be oke

    public string Translate(string resource, System.Globalization.CultureInfo from, System.Globalization.CultureInfo to)
        {
            string[] VALIDTRANSLATIONMODES = new string[] 
 {"en_zh", "en_fr", "en_de", "en_it", "en_ja", "en_ko", "en_pt", "en_es", 
 "zh_en", "fr_en", "fr_de", "de_en", "de_fr", "it_en", "ja_en", "ko_en", 
 "pt_en", "ru_en", "es_en"};
            Uri uri = new Uri("http://www.babelfish.com");
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
            //request.Referer = BABELFISHREFERER;
            string postsourcedata;
            string translationmode = "en_fr";
            postsourcedata = "lp=" + translationmode +
                "&tt=urltext&intl=1&doit=done&urltext=" +
            HttpUtility.UrlEncode(resource);
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = postsourcedata.Length;
            request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
            Stream writeStream = request.GetRequestStream();
            UTF8开发者_Go百科Encoding encoding = new UTF8Encoding();
            byte[] bytes = encoding.GetBytes(postsourcedata);
            writeStream.Write(bytes, 0, bytes.Length);
            writeStream.Close();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream responseStream = response.GetResponseStream();
            StreamReader readStream = new StreamReader(responseStream, Encoding.UTF8);
            string page = readStream.ReadToEnd();
            Regex reg = new Regex(@"<div style=padding:10px; lang=..>(.*?)</div>");
            MatchCollection matches = reg.Matches(page);
            if (matches.Count != 1 || matches[0].Groups.Count != 2)
            {
                return "erro";
            }
            return matches[0].Groups[1].Value;



        }

Thats what i ended up doing

string fromCulture = from.Name;
            string toCulture = to.Name;
            string translationMode = string.Concat(fromCulture, "_", toCulture);

            string url = String.Format("http://babelfish.yahoo.com/translate_txt?lp={0}&tt=urltext&intl=1&doit=done&urltext={1}", translationMode, HttpUtility.UrlEncode(resource));
            WebClient webClient = new WebClient();
            webClient.Encoding = System.Text.Encoding.Default;
            string page = webClient.DownloadString(url);

            int start = page.IndexOf("<div style=\"padding:0.6em;\">") + "<div style=\"padding:0.6em;\">".Length;
            int finish = page.IndexOf("</div>", start);
            string retVal = page.Substring(start, finish - start);

This previous answer might help: Using c# to call google translator. It references this codeplex project: http://languagetranslator.codeplex.com/ which uses the Google Translation API.

It might take a few moments to find the code which does the job you want but I usually find that it's the best way to learn (for me at least!)

Your regex is failing because there are no instances of what you are searching for in the downloaded text.

<div style=padding

does not exist. Perhaps some quotes?

<div style="padding //etc
