有人知道通过URL怎么获得一个网站的状态码吗？

Question

状态？ Encoding myEncoding = Encoding.GetEncoding("gb2312");
            string param = "wd=123";//HttpUtility.UrlEncode("wd", myEncoding) + "=" + HttpUtility.UrlEncode("123", myEncoding);            byte[] postBytes = Encoding.ASCII.GetBytes(param);            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://www.baidu.com/s?wd=123");
            //HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://www.codeproject.com/KB/cs/giospdfsplittermerger/GiosPdfSplitterMerger.zip");
            req.Method = "Get";
            //req.ContentType = "application/x-www-form-urlencoded;charset=gb2312";
            //req.ContentLength = postBytes.Length;
            WebProxy por = WebProxy.GetDefaultProxy();
            por.Credentials = new System.Net.NetworkCredential("zxd", "123456");
            req.Proxy = por;
            //using (Stream reqStream = req.GetRequestStream())
            //{
            //    reqStream.Write(postBytes, 0, postBytes.Length);
            //}
            byte[] data = new byte[1024 * 10];
            using (WebResponse wr = req.GetResponse())
            {
                //在这里对接收到的页面内容进行处理
                string herders = wr.Headers.ToString();
                wr.GetResponseStream().Read(data, 0, data.Length);
                
            }

Answer 1

是不是网站的源代码呢?要是是的话可以参考下
  private void button1_Click(object sender, EventArgs e)
        {
    
            int Page = 1;
            string txtOne = System.Web.HttpUtility.UrlEncode(this.textBox1.Text, System.Text.Encoding.Default);
            string txtTwo = System.Web.HttpUtility.UrlEncode(this.textBox2.Text, System.Text.Encoding.Default);
            string Sosourl = "http://www.soso.com/q?w=" + txtOne + " " + txtTwo + "&lr=&sc=web&ch=w.p&filter=1&num=10&gid=&cin=&site=&pg=" + Page;
            WebRequest request = WebRequest.Create(Sosourl);
            WebResponse response = request.GetResponse();
            Stream resStream = response.GetResponseStream();
            StreamReader sr = new StreamReader(resStream, System.Text.Encoding.Default);
            string Webcode = sr.ReadToEnd();
            try
            {
                StreamWriter sw = new StreamWriter(@"c:\1.txt");
                sw.WriteLine(Webcode);
                MessageBox.Show("写入完成");
            }
            catch(Exception s)
            {
                MessageBox.Show(s.Message.ToString());
 
            }        }

我现在是每条数据每个网站的TimeOut设置为10秒来访问每个网站。
