Question

我想要从id = statsTable的表中确定所有元素，并希望我可以将所有数据读入csv。

这是我到目前为止所做的：

// Create a request for the URL. 
WebRequest request = WebRequest.Create("http://www.pgatour.com/stats/stat.120.html");
Console.WriteLine("Requesting data from: http://www.pgatour.com/stats/stat.120.html");

// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;

WebResponse response = request.GetResponse();

using (Stream stream = response.GetResponseStream())
{
    StreamReader reader = new StreamReader(stream);

    // covert html to string
    String responseString = reader.ReadToEnd();

    HtmlDocument doc = new HtmlDocument();

    doc.LoadHtml(responseString);

    var desktopFolder = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
    var fullFileName = Path.Combine(desktopFolder, "GolfStats.csv");

    using (var PlayerFile = new StreamWriter(fullFileName))
    {
        PlayerFile.WriteLine("Data downloaded: " + DateTime.Now);

        var myTable = doc.DocumentNode
                        .Descendants("table")
                        .Where(table => table.Attributes.Contains("id"))
                        .SingleOrDefault(table => table.Attributes["id"].Value == "statsTable");

        var myTableValues = myTable.Descendants("td");

        foreach (var tdV in myTableValues)
        {
            PlayerFile.WriteLine(tdV.InnerText);
            Console.WriteLine(tdV.InnerText);
        }

        PlayerFile.Flush();
    }
}

问题是我的csv只是将数据列在一个列中，以及拾取放在表中的广告（请参阅webRequest中的url）。如果你可以帮我输出表格格式的数据，那就太棒了！

您为每个表格单元格创建一个新行。要更改它，以便每个表行都有一个单独的行替换

var myTableValues = myTable.Descendants("td");
foreach (var tdV in myTableValues)
{
    PlayerFile.WriteLine(tdV.InnerText);
    Console.WriteLine(tdV.InnerText);
}

与

var myTableRows = myTable.Descendants("tr").Where(tr => tr.Attributes.Contains("id"));
foreach (var tr in myTableRows)
{
    string line = string.Join(";", tr.Descendants("td").Select(td => td.InnerText));
    PlayerFile.WriteLine(line);
    Console.WriteLine(line);
}

.Where(tr => tr.Attributes.Contains("id"))过滤了广告，因为广告的表格行没有ID而所有玩家行都有。
