如何直接从主机上的xml文件中获取项目列表？更确切地说，我想要这个xml文件http://gamerpro.webd.pl/data/modlist.xml我拿出了一个项目列表并听取了代码

SELECT p.user_id 
FROM profiles p INNER JOIN
     user_activity_log ual
     ON p.user_id = ual.user_id 
WHERE p.status IN ('wip', 'declined', 'cancelled') AND
      ual.last_activity < NOW() - INTERVAL 1 MINUTE AND
      NOT EXISTS (SELECT 1
                  FROM email_logs el
                  WHERE p.user_id = el.user_id AND
                        el.sent_datetime >= NOW() - INTERVAL 1 MINUTE
                 )

using System;
using System.Xml;

namespace ReadXMLfromURL
{
    /// <summary>
    /// Summary description for Class1.
    /// </summary>
    class Class1
    {
        static void Main(string[] args)
        {
            String URLString = "http://localhost/books.xml";
            XmlTextReader reader = new XmlTextReader (URLString);

            while (reader.Read()) 
            {
                switch (reader.NodeType) 
                {
                    case XmlNodeType.Element: // The node is an element.
                        Console.Write("<" + reader.Name);

                        while (reader.MoveToNextAttribute()) // Read the attributes.
                            Console.Write(" " + reader.Name + "='" + reader.Value + "'");
                        Console.Write(">");
                        Console.WriteLine(">");
                        break;
                    case XmlNodeType.Text: //Display the text in each element.
                        Console.WriteLine (reader.Value);
                        break;
                    case XmlNodeType. EndElement: //Display the end of the element.
                        Console.Write("</" + reader.Name);
                        Console.WriteLine(">");
                        break;
                }
            }
        }
    }

你可以做这样的事情

// Make your request
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, requestURL);
request.Headers.Add("Accept", "application/xml");
HttpResponseMessage response = client.SendAsync(request).Result;

// Parse your response
if (response.IsSuccessStatusCode)
{
    using (Stream httpResponseStream = response.Content.ReadAsStreamAsync().Result)
    {
        XDocument responseXML = XDocument.Load(httpResponseStream);

        // My Chosen element is the element you're looking for
        IEnumerable<XElement> myElements = responseXML.Root.Elements("MyChosenElement");

        foreach (XElement myEl in myElements)
        {
            // Access each element like this myEl.Child
            // Do what you'd like with it
        }
    }
}
