c# - 获取列表

Question

我正在使用 linq 代码解析 XML 文件。这是我的代码。我想要绑定(bind)详细信息和图像列表。

XmlSerializer serializer = new XmlSerializer(typeof(Notchs));
XDocument xmlDoc = XDocument.Parse(dataInXmlFile);
Notchs notchs = (Notchs)serializer.Deserialize(xmlDoc.CreateReader());

var query = from l in xmlDoc.Descendants("Person")
            select new Notch
            {
                name = (string)l.Attribute("name").Value,
                Titles = l.Element("Details").Elements("detail")
                           .Select(s => s.Attribute("games").ToString())
                           .ToList(),

                Image = l.Element("Details").Elements("detail").Elements("event_image").Elements("image")
                         .Select(x => x.Attribute("url").ToString()).ToList()
            };

foreach (var result in query)
{
    Console.WriteLine(result.name);
    foreach (var detail in result.Titles)
    {
        Console.WriteLine(detail);
    }
}
NotchsList.ItemsSource = query.ToList();

这是我正在使用 XML 文件，我想获取带有图像的名称和游戏

<?xml version="1.0" encoding="utf-8"?>
<root>
 <Peoples>
  <Person name="Raja">
   <Details>
    <detail games="Cricket">
      <event_image>
        <image  url="http://Cricket.jpeg"/>
      <event_image>
    </detail>
    <detail games="Foot Ball">
     <event_image>
       <image  url="http://FootBall.jpeg"/>
     <event_image>
    </detail>
    <detail games="Volley Ball">
     <event_image>
      <image  url="http://.Volley.jpeg3"/>
     <event_image>
    </detail>
   </Details>
  </Person>
  <Person name="Rama">
    <Details>
     <detail games="Chess">
      <event_image>
        <image  url="http://Chess.jpeg"/1>
      <event_image>
     </detail>
     <detail games="Table Tennis">
      <event_image>
       <image  url="http://TTennis.jpeg"/>
      <event_image>
     </detail>
     <detail games="Carrom">
      <event_image>
       <image  url="http://Carrom.jpeg"/>
      <event_image>
     </detail>
   </Details>
  </Person>
 </Peoples>
</root>

我的代码就像

public class Notch
{
    [XmlAttribute("name")]
    public string name { get; set; }

    [XmlAttribute("games")]
    public List<string> Titles { get; set; }

    [XmlAttribute("url")]
    public List<string> Image { get; set; }
}


[XmlRoot("root")]
public class Notchs
{
    [XmlArray("Peoples")]
    [XmlArrayItem("Person")]
    [XmlArrayItem("Details")]
    public ObservableCollection<Notch> Collection { get; set; }
}

我的 xaml 文件

  <ListBox x:Name="NotchsList" 
        SelectionChanged="NotchsList_SelectionChanged"   Margin="0,-5.25,22,0"  Grid.Row="1" HorizontalAlignment="Right" Width="768" Grid.Column="1" Grid.RowSpan="3" d:LayoutOverrides="VerticalMargin">
        <ListBox.ItemTemplate>
            <DataTemplate>

                    <StackPanel Margin="0,0,0,0" Orientation="Vertical" Grid.ColumnSpan="2"
                        Grid.Column="0"
                        Height="160"
                        VerticalAlignment="Top">
                        <StackPanel Background="#eb2427" Orientation="Vertical">
                            <TextBlock Grid.Row="1"  FontFamily="Calibri" FontSize="34" FontWeight="Bold"  FontStyle="Normal" Margin="10,0,0,0"
                                Text="{Binding name}"
                                   />               
                        </StackPanel>
                        <StackPanel Orientation="Horizontal">
                             <TextBlock Grid.Row="1" FontFamily="Calibri" FontSize="32" Foreground="#a7a9ac"
                                Text="{Binding games}" ScrollViewer.HorizontalScrollBarVisibility="Visible"/>     

                        </StackPanel>
                        <StackPanel Orientation="Horizontal">
                            <Image Grid.Row="1"  Source="{Binding Image}" VerticalAlignment="top" />
                        </StackPanel>           
                </StackPanel>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

我得到的输出如下

拉贾

  System.collection.generic.list'1[System.String]

  System.collection.generic.list'1[System.String]

拉玛

  System.collection.generic.list'1[System.String]

  System.collection.generic.list'1[System.String]

Answer 1

你需要改变

s.Attribute("games").ToString()
x.Attribute("url").ToString()

至:

s.Attribute("games").Value.ToString()
x.Attribute("url").Value.ToString()
