C#无法正确获取网站页面的源码
url:http://www.
我的代码:
        public static string GetPage(string url)
        {
                HttpWebRequest request = null;
                HttpWebResponse response = null;
                StreamReader reader = null;
                try
                {
                        request = (HttpWebRequest)WebRequest.Create(url)
                        request.Timeout = 30000;
                        request.Method = "GET";
                        request.KeepAlive = false;
                        request.AllowAutoRedirect = false;
                        response = (HttpWebResponse)request.GetResponse();
                        if (response.StatusCode == HttpStatusCode.OK)
                        {
                                reader = new StreamReader(response.GetResponseStream(), true);
                                string html = reader.ReadToEnd();
                                return html;
                        }
                }
                catch { }
                finally
                {
                        if (response != null)
                        {
                                response.Close();
                                response = null;
                        }
                        if (reader != null)
                                reader.Close();
                        if (request != null)
                                request = null;
                }
                return string.Empty;
        }
        protected void Button1_Click(object sender, EventArgs e)
        {
                TextBox1.Text = GetPage("http://www.);
        }
获取到的部分源码:
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Welcome</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta name="description" content="">
    <meta name="author" content="">
    <script>
            var l7_scheme = 'http';
            var l7_port = '80';
            var l7_action_url = "http://resources.
            var l7_vcode_img = 'http://resources.';
            var l7_domain_img = 'default';
            l7_domain_img = "*.
l7_scheme = "http";

            l7_domain_img = l7_scheme + '://resources.'+ l7_domain_img + '_' + l7_port + '.jpg';
            document.write("<script src='"+ l7_scheme +"://resources.'></script><link href='"+ l7_scheme +"://resources.' rel='stylesheet' type='text/css'>");
在浏览中查看到的部分源码:

</div>
<script language="javascript">
fw.onReady(function(){
    Chart.init();   
    DrawLine.bind("chartsTable","has_line");

        DrawLine.color('#499495');
    DrawLine.add((parseInt(0)*11+5+1),2,11,0);
        DrawLine.color('#E4A8A8');
    DrawLine.add((parseInt(1)*11+5+1),2,11,0);
        DrawLine.color('#499495');
    DrawLine.add((parseInt(2)*11+5+1),2,11,0);
        DrawLine.color('#E4A8A8');
为什么会这样,请各位高手指点下!

怎么没有高手来解决下!用VB6.0,或者VBA都可以正确获取全部的源码的,唯独就是VS下写的代码就获取不正常。但是在本地获取源代码的话,电脑要随时开着,时间长了电脑受不了,于是用C#写代码,把它放到远程服务器上,来执行代码获取并过滤写入数据库,望求高手解答,谢谢!

现在的问题就是C#写代码获取的源代码就不正常,不过上面的代码有些网站是可以正常获取的,所以说很郁闷!

request.AllowAutoRedirect = false;
由于你设置这个属性。。他就不能读取一些做过转跳的网站的源代码.
所以把 request.AllowAutoRedirect =true就ok了。。
