问题描述

我想要链接提取器的C#代码，例如
如果我以www.yahoo.com的身份输入
那么我的输出应该是www.yahoo.com上的所有内部消息，都应保存在一个文本文件中.

我知道我必须使用LinksExtractor类，但没有得到怎么做

例如ip:www.yahoo.com
o/p:
www.yahoo.com/sports
www.yahoo.com/Business

i know i have to use LinksExtractor class but not getting how to do

e.g. ip:www.yahoo.com
o/p:
www.yahoo.com/sports
www.yahoo.com/Business

推荐答案

开始吧:)

创建公共列表链接:

Let''s start :)

Create a public List links:

List<string> links = new List<string>();</string></string>

private void FindLinks(string url)
{
   links.Clear();

   WebBrowser webBrowser1 = new WebBrowser();
   webBrowser1.Navigate(url);
   webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}

void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
   

   if (((WebBrowser)sender).Document != null)
   {
      HtmlElementCollection col = ((WebBrowser)sender).Document.GetElementsByTagName("a");

      foreach (HtmlElement elem in col)
      {
         if (elem.GetAttribute("href").StartsWith("http://"))
            links.Add(elem.GetAttribute("href"));
      }
   }
}

调用函数使用:

Call function using:

FindLinks(@"http://www.google.gr/");

所有链接都将在列表链接中

All links will be in the List links
