所以我有这个feed，我缩小了不需要的节点。

服务重演。

然后我有了这段代码来获取数据：

 void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) 
{ 
    if (e.Error == null) 
    { 
        if (e.Result != null) 
        { 
            XDocument doc = XDocument.Parse(e.Result); 
            XNamespace ns = "http://schemas.datacontract.org/2004/07/BusExpress.ClassLibrary";
            var routeNames = (from n in doc.Descendants(ns + "ArrayOfService") 
                             select new RootContainer

                             {

                                 Stops = (from s in n.Elements(ns + "Service").Elements(ns + "client").Elements(ns + "services").Elements(ns + "Service").Elements(ns + "Service")

                                          select new Stops

                                          {
                                              StopName = s.Element(ns + "serviceDescription").Value,
                                              serviceIconUrl = s.Element(ns + "Service").Element(ns + "serviceIconUrl").Value,
                                            //  NaptanCode = s.Element(ns + "Service").Element(ns + "serviceIconUrl").Value,

                                             // StopId = s.Element(ns + "stop").Element(ns + "stopId").Value 

                                          }).ToList() 
                             }).Single();


            listBox1.ItemsSource = routeNames.Stops;

在xmal页面中它的绑定如下：

   <ListBox x:Name="listBox1"  ScrollViewer.VerticalScrollBarVisibility="Disabled"  Foreground="Red" Height="160" VerticalAlignment="Bottom" Margin="-10,0,10,377" Grid.Row="1">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel>
                    <!-- <TextBlock Text="Bus Stops: "/>-->
                    <TextBlock Text="{Binding StopName}"/>
                    <!--   <TextBlock Text="Timetables: "/>-->
                      <TextBlock Text="{Binding serviceIconUrl}"/>                       
                   <!--   <TextBlock Text="{Binding StopId}"/>-->
                    <TextBlock Text=" "/>
                </StackPanel>
            </DataTemplate>

        </ListBox.ItemTemplate>
    </ListBox>

为什么我没有回复？我知道这很简单，就是找不到它。

1 个答案:

答案 0 :(得分：1)

您的LINQ查询末尾包含太多Service元素，但它们找不到。

目前：

n.Elements(ns + "Service")
 .Elements(ns + "client")
 .Elements(ns + "services")
 .Elements(ns + "Service")
 .Elements(ns + "Service")

应该是：

n.Elements(ns + "Service")
 .Elements(ns + "client")
 .Elements(ns + "services")
 .Elements(ns + "Service")
