我正在开发一个程序，我在做一个HTTPWebrequest，作为响应，我得到了XML数据。 （此时我将回复放在消息框中）

我只想在列表框中显示ExpectedDeperatureTime。

我尝试使用以下代码执行此操作：

string xmlFormat = responseFromServer;

            XDocument doc = XDocument.Parse(xmlFormat);

            var list = doc.Root.Elements("ExpectedDepartureTime")
                          .Select(element => element.Value);


            foreach (string i in list)
            {
                lstHours.Items.Add(i);
            }

我在另一个帖子上找到了这段代码：How can I transform XML into a List<string> or String[]?

当我在线程上使用'id'的示例时它可以工作但不能用我的xmldata我不知道为什么......

它变大吗？ 我忘了什么吗？

谢谢！

这将获得出发时间列表：

XNamespace ns = "http://www.siri.org.uk/";

List<DateTime> departureTimes = doc.Descendants(ns + "ServiceDelivery")
   .Elements(ns + "StopMonitoringDelivery")
   .Elements(ns + "MonitoredStopVisit")
   .Elements(ns + "MonitoredVehicleJourney")
   .Elements(ns + "MonitoredCall")
   .Elements(ns + "ExpectedDepartureTime")
   .Select(x => (DateTime)x)
   .ToList();

或作为字符串

List<string> departureTimes2 = 
    departureTimes.Select( dt => dt.ToString() ).ToList();
