我正在尝试返回网站的html scipt，输入url。问题是脚本返回部分html而不是整个部分。具体问题是网站http://www.4xinvestmentgroup.com。那么，您对可能出现的问题有任何想法吗？
首先我尝试了以下脚本：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string url = "http://www.4xinvestmentgroup.com";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.GetEncoding(res.CharacterSet));
Console.WriteLine(sr.ReadToEnd());
sr.Close();
Console.WriteLine("Press enter to close...");
Console.ReadLine();
}
}
}
之后我尝试了以下脚本：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string url = "http://www.4xinvestmentgroup.com";
WebClient client = new WebClient();
string reply = client.DownloadString(url);
Console.WriteLine(reply);
Console.WriteLine("Press enter to close...");
Console.ReadLine();
}
}
}
在两个解决方案中，返回的html是：

html1/DTD/xhtml1-strict.dtd">

但是，如果您从浏览器中查看原始html，则详细信息会更加丰富。

似乎请求被重定向到网站的移动版本。尝试将用户代理字符串设置为桌面浏览器使用的字符串。例如：
<强> HttpWebRequest的
req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)";
<强> Web客户端
client.Headers.Add("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

使用WebBrowser Control获取此站点的完整html的一种方法。
创建窗体表单应用程序。从工具箱添加webbrowser控件。内部表单加载事件使用以下代码。
webBrowser1.Navigate("http://www.4xinvestmentgroup.com");
while(webBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
// just to keep it busy until document is not loaded completely.
Application.DoEvents();
}
string html = webBrowser1.DocumentText;
