What do you think the easiest way to do this?

推荐答案

我认为这就是你要找的它打印你所请求页面的html代码：

I think this is what you are looking for it prints the html code of your requested page :

public static void Main(string[] args)
       {
           string URl = "http://www.beatport.com/genre/electro-house/17/top-100";

           WebClient client = new WebClient();

           client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

           Stream data = client.OpenRead(URl);
           StreamReader reader = new StreamReader(data);
           string s = reader.ReadToEnd();

           Console.WriteLine(s);
           data.Close();
           reader.Close();
           Console.ReadKey();
       }
