Look for Baidu and GG, English Yahoo also looked for, did not find ready-made.
Had to write one himself, crawl very accurate. ^_^. Friends who need to take.
I don't know how many technical friends there are. ）

In the writing of a small SEO tool, simulation spiders crawl links, but also detection of spiders recognized effective links!!

(Cause is a few GG group of friends Encounter, malicious false link deception, the surface to see who also can not see out, but the actual spider a crawl on the leak stuffing, with my software a test, can also be the true colours ...) ）

Nonsense not to say, the code below, attached screenshot of a ... I use a friend of the environmental protection site to detect the effect of the map, probably see.

private string Getalexa (int idx, string url)


        {


//sourcecode by http://77521.cn


string css = "";


string result = "no rank";


string html = Func.gethttppage ("http://www.alexa.com/search?q=" + URL.) Replace ("http://", ""), "Utf-8");


string Patt = "<link href=\" ([^\ ' \\s]*?] \ "_fcksavedurl=" ([^\ "' \\s]*?) \ "" _fcksavedurl= "\" ([^\ "' \\s]*?) \ "" _fcksavedurl= "\" ([^\ "' \\s]*?) \ "Type=\" Text/css\ "rel=\" stylesheet\ ">";


Regex reg = new Regex (Patt, regexoptions.ignorecase);


MatchCollection mc = Reg. Matches (HTML);


if (MC. Count <= 0)


{//Wrong


Dgedit (IDX, 7, "no rankings");


        }


else


{//Find CSS


CSS = func.gethttppage (mc[0). Result ("$"), "Utf-8");


reg = new Regex ("Rank": ([\\s\\s]*?) </a> ", regexoptions.ignorecase);


MC = Reg. Matches (HTML);


if (MC. Count <= 0)


        {


Dgedit (IDX, 7, "no rankings");


        }


Else


        {


string Mao = mc[0]. Result ("$");


String Mao2 = Mao. Replace ("\", ""). Replace ("'", ""). Replace ("", "");


Mao2 = Regex.Replace (Mao2, "<\\!--. +?-->");


reg = new Regex ("<span[\\s\\s]*?class=[\"]? +?) [\] ']?> (. +?) </span> ", regexoptions.ignorecase);


MC = Reg. Matches (MAO2);


if (MC. Count <= 0)


            {


Dgedit (IDX, 7, "no rankings");


            }


else


            {


//textbox1.text = Mao2;


for (int n = 0; n < MC. Count; n++)


                {


if CSS. IndexOf (Mc[n]. Result ("$")!=-1)


                    {


                         Mao2 = Regex.Replace (Mao2, "<span[^>]*?class=" + mc[n). Result ("$") + ">.+?</span>",

                        //textbox1.text = TextBox1.Text + "\r\n\r\ n------------------------------------------
                    }
                }
                 Mao2 = Regex.Replace (Mao2, "<[\\s\\S]+?>", "");
                Mao2 = Regex.Replace (Mao2, "", "");
                Mao2 = Regex.Replace (Mao2, " ", "");
                Mao2 = Regex.Replace (Mao2, "|", "");
                Mao2 = Mao2. Replace ("\ R", ""). Replace ("\ n", "");
                dgedit (idx, 7, MAO2);
                return MAO2;
           }
         }
      }
    return result;
   }

Again nonsense point, such code may be common webmaster is useless, hair in the lounge, is also a small original, Baidu GG Yahoo no relevant code Kazakhstan.

Have a tutorial class site friends, don't miss Ah. ^_^

Although a bit unlikely, I hope you can keep a link when you reprint.

Code, Gethttppage is a function of crawling Web page code. Such a simple one should be available on their own. Don't say it.
Dgedit is a delegate.
