c#最简单的数据抓取

  创建一个程序在button按钮的事件中，写下

 

          private string url = http://www.baidu.com/;
          private WebClient wc = new WebClient();

           private void button1_Click(object sender, EventArgs e)
        {
            string articleData = Encoding.UTF8.GetString(wc.DownloadData(string.Format(url)));
            string pth = Path.GetFullPath(Properties.Settings.Default.ToString()) + ".txt";
            if (!File.Exists(pth))
            File.AppendAllText(pth, articleData, Encoding.UTF8);
        }

 

    抓取到整个页面的html。
