推荐答案

查看此处: C#站:获取带有HTTP的网页.
您可以将结果文本解析为xml，但是我建议使用正则表达式提取所需的内容.

Look here: C# Station: Fetching Web Pages with HTTP.
You can parse the resulted text as xml, but i suggest using regular expressions to extract what you need.

我认为元数据一词是指Headers信息，如果这样的话，下面的代码将有所帮助您开始，

I assume the term metadata refers to the Headers information, if so then following code will help you to start,

namespace ConsoleApplication24
{
    using System;
    using System.Net;
    class Program
    {
        static void Main(string[] args)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.Codeproject.com");
            request.Method = "GET";
            IWebProxy proxy = WebRequest.GetSystemWebProxy();
            proxy.Credentials = CredentialCache.DefaultCredentials;
            request.Proxy = proxy;

            using (WebResponse response = request.GetResponse())
            {
                WebHeaderCollection collection = response.Headers;

                Array.ForEach(collection.AllKeys,
                    key =>
                    {
                        Console.WriteLine("{0,20}:{1}", key, string.Concat(collection.GetValues(key)));
                    });
            }
        }
    }
}

该代码将产生以下输出，

This code will produce following output,

    Proxy-Connection:Keep-Alive
          Connection:Keep-Alive
      Content-Length:94210
       Cache-Control:private
        Content-Type:text/html; charset=utf-8

Press any key to continue . . .

或者，如果我们要获取元标记，请看一下，

C#解析元标记 [

Or if we want to get meta tag please have a look,

C# Parse Meta Tags[^]

Hope it helps a bit :)
