我尝试了我的代码，无法获取表数据，因为它没有表ID，并且带有一些棘手的代码(我认为)，这是我的代码:

I tried my code, cannot get the table data, because it do not have table id and with some tricky code (I think), here is my code: 

 static void Main(string[] args)
        {
            HtmlWeb webClient = new HtmlWeb();

            HtmlAgilityPack.HtmlDocument doc = webClient.Load("http://racing.hkjc.com/racing/Info/Meeting/Results/English/Local/20161116/HV/3");
            HtmlNode table = doc.DocumentNode.SelectSingleNode("//table");
        

                var cells = (from cell in table.SelectNodes("./tr")
                             select cell.InnerText).ToList();

            foreach (var cell in cells)

            {
                Console.Write(cell);
                Console.ReadKey();
            }

有人知道如何从此页面获取数据吗?以及使用它的任何棘手的代码?

WKCALVIN，

Hi WKCALVIN,

谢谢您在这里发布.

对于您的问题，您可以使用F12从网站上的表格中获取信息.

For your question, you could use F12 to get the information from the table in your website.

这是在键盘上单击F12后的屏幕截图.

Here is the screenshot after click F12 in your keyboard.

我使用代码获取此表的值.

I use the code to get the value of this table.

请尝试以下代码.我尝试过这个.效果很好.

Please try the following code. I tried it. It works well.

using HtmlAgilityPack;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace get_table_from_website
{
    class Program
    {
        static void Main(string[] args)
        { 
            WebClient webClient = new WebClient();
            string page = webClient.DownloadString("http://racing.hkjc.com/racing/Info/Meeting/Results/English/Local/20161116/HV/3");

            HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
            doc.LoadHtml(page);

            List<List<string>> table = doc.DocumentNode.SelectSingleNode("//table[@class='tableBorder trBgBlue tdAlignC number12 draggable']")
                        .Descendants("tr")
                        .Skip(1)
                        .Where(tr => tr.Elements("td").Count() ==12)
                        .Select(tr => tr.Elements("td").Select(td => td.InnerText.Trim()).ToList())
                        .ToList();           
        }
    }

}
