本示例使用 C# 通过 HttpWebRequest 和 HttpWebResponse 获取新浪网站的内容，并利用正则表达式去除 HTML 标签，最终输出纯文本信息。

        HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://www.sina.com.cn");
        myReq.Method = "GET";
        myReq.ContentType = "application/x-www-form-urlencoded";
        HttpWebResponse myRes = (HttpWebResponse)myReq.GetResponse();
        Stream resStream = myRes.GetResponseStream();
        System.IO.StreamReader streamReader = new StreamReader(resStream, System.Text.Encoding.GetEncoding("GB2312"));
        string mystring = streamReader.ReadToEnd();
        Regex Myregex = new Regex(@"<[^>]*>");
        mystring = Myregex.Replace(mystring,"");
        myRes.Close();
        resStream.Close();
        Response.Write(mystring);
