使用HtmlAgilityPack将HtmlTable填入DataTable

　　　　　　　HtmlAgilityPack.HtmlWeb hw = new HtmlAgilityPack.HtmlWeb(); HtmlAgilityPack.HtmlDocument doc = hw.Load("C:\\Users\\u1\\Desktop\\test html.html");
            HtmlAgilityPack.HtmlNode rootNode = doc.DocumentNode;//获取文档的根节点 //   //*[@id="report1"]/tbody
            string xpath = "//*[@id='report1']/tbody"; HtmlAgilityPack.HtmlNode node = rootNode.SelectSingleNode(xpath);//获取表格
            foreach (var script in node.Descendants("script").ToArray()) script.Remove(); foreach (var style in node.Descendants("style").ToArray()) style.Remove(); string innerText = node.OuterHtml;//到这里就是纯纯的表格了 
            var trNodes = node.SelectNodes("tr"); DataTable dt = new DataTable(); for (int i = 0; i < 100; i++)   //给表格增长100个列
 { DataColumn dc = new DataColumn(); dt.Columns.Add(dc); } foreach (var trnod in trNodes) //遍历行
 { //dt.Rows.Add()
                DataRow dr = dt.NewRow(); var tdNodes = trnod.SelectNodes("td"); for (int i = 0; i < tdNodes.Count; i++) //遍历列
 { dr[i] = tdNodes[i].InnerText; } dt.Rows.Add(dr); } // 全部的数据读取到了datatable 中
