Question

我已经尝试了几个小时，并在网上搜索有关如何拉出具有相同名称的多个元素但不同属性的示例，并将这些属性绑定到我的应用程序中的我的XAML for wp7，

我解释的最简单方法就是简单地告诉你，

继承人到目前为止我所拥有的

       public class Match
    {
        public string HomeTeam { get; set; }
        public string AwayTeam { get; set; }
        public string HomeScore { get; set; }
        public string AwayScore { get; set; }
        public string GoalsPlayer { get; set; }
        public string goal { get; set; }
        public string GoalsTime { get; set; }
        public string DismissalsPlayer { get; set; }
        public string DismissalsTime { get; set; }
        public string BookingPlayer { get; set; }
        public string BookingTime { get; set; }
        public string GameTime { get; set; }
    }

 void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        XElement element = XElement.Parse(e.Result);
        try
        {
            listBox2.ItemsSource = from item in element.Descendants("competition")
                                   from match in item.Elements("match").Where(arg => arg.Attribute("awayTeam").Value == team | arg.Attribute("homeTeam").Value == team)
                                   select new Match
                                   {
                                       HomeTeam = (string)match.Attribute("homeTeam"),
                                       AwayTeam = (string)match.Attribute("awayTeam"),
                                       HomeScore = (string)match.Attribute("homeTeamScore"),
                                       AwayScore = (string)match.Attribute("awayTeamScore"),
                                       GoalsPlayer = (string)match.Attribute("playerName"),
                                       GoalsTime = (string)match.Attribute("time"),
                                   };
        }
        catch (Exception ex)
        {
             Debug.WriteLine(ex.StackTrace);
        }

这是我的XAML

<ListBox Name="listBox2" Grid.Row="0">
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Name="teams" Orientation="Vertical">
                                <StackPanel Orientation="Horizontal">
                                    <TextBlock Margin="0,10,0,0" Foreground="White" HorizontalAlignment="Left" Text="{Binding HomeTeam}"/>
                                    <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding HomeScore}" TextWrapping="Wrap" FontSize="20" />
                                    <TextBlock Margin="0,10,0,0" Foreground="White" HorizontalAlignment="Left" Text="{Binding AwayTeam}"/>
                                    <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding AwayScore}" TextWrapping="Wrap" FontSize="20" />
                                </StackPanel>
                                <StackPanel Name="scores" Orientation="Horizontal">
                                    <TextBlock Margin="0,10,0,0" Foreground="White" Text="{Binding GoalsPlayer}" TextWrapping="Wrap" FontSize="20" />
                                    <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding GoalsTime}" TextWrapping="Wrap" FontSize="20" />
                                </StackPanel>
                                <StackPanel Name="dismissals">
                                    <TextBlock Foreground="White" Text="{Binding DismissalsPlayer}" TextWrapping="Wrap" FontSize="20"/>
                                    <TextBlock Foreground="White" Text="{Binding DismissalsTime}" TextWrapping="Wrap" FontSize="20"/>
                                </StackPanel>
                            </StackPanel>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>

这是我的XML

<match homeTeam="Arsenal" awayTeam="Liverpool" homeTeamScore="0" awayTeamScore="2">
<goal time="77:13" playerName="Aaron Ramsey" />
<goal time="89:57" playerName="Luis Suarez"/>
<dismissal time="69:59" playerName="Emmanuel Frimpong"/>
</match>

我知道我的目标页面上只会有一个条目，这将是我的XML中的第一个目标元素

我怎样才能实现并实施每一个

<goal ...>
<goal ...>

进入我的Datatemplate，目前只显示第一个条目，另一个潜在的问题是我不能保证会有多少目标，所以我真的不确定如何完全实现它

感谢

playerName是否match甚至可以解决？因为这是您在XML查询中解析它的地方。

无论如何，你在这里寻找的是一个可以保存在Match对象的list属性中的子对象：

listBox2.ItemsSource = from item in element.Descendants("competition")
                       from match in item.Elements("match")
                           .Where(arg => arg.Attribute("awayTeam").Value == team || 
                                         arg.Attribute("homeTeam").Value == team)
                       select new Match
                       {
                           HomeTeam = (string)match.Attribute("homeTeam"),
                           AwayTeam = (string)match.Attribute("awayTeam"),
                           HomeScore = (string)match.Attribute("homeTeamScore"),
                           AwayScore = (string)match.Attribute("awayTeamScore"),
                           Goals = match.Elements("goals").Select(ev => new MatchEvent
                           {
                               Player = (string)ev.Attribute("playerName"),
                               Time = (string)ev.Attribute("time")
                           }).ToList(),
                           Dismissals = match.Elements("dismissals").Select(ev => new MatchEvent
                           {
                               Player = (string)ev.Attribute("playerName"),
                               Time = (string)ev.Attribute("time")
                           }).ToList(),
                       };

更新后的XAML：

<ListBox Name="listBox2" Grid.Row="0">
    <ListBox.ItemTemplate>
        <DataTemplate>
             <StackPanel Name="teams" Orientation="Vertical">
             <StackPanel Orientation="Horizontal">
                  <TextBlock Margin="0,10,0,0" Foreground="White" HorizontalAlignment="Left" Text="{Binding HomeTeam}"/>
                  <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding HomeScore}" TextWrapping="Wrap" FontSize="20" />
                  <TextBlock Margin="0,10,0,0" Foreground="White" HorizontalAlignment="Left" Text="{Binding AwayTeam}"/>
                  <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding AwayScore}" TextWrapping="Wrap" FontSize="20" />
              </StackPanel>
              <ItemsControl ItemsSource="{Binding Goals}">
                  <ItemsControl.ItemTemplate>
                      <DataTemplate>
                          <StackPanel Name="scores" Orientation="Horizontal">
                              <TextBlock Margin="0,10,0,0" Foreground="White" Text="{Binding Player}" TextWrapping="Wrap" FontSize="20" />
                              <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding Time}" TextWrapping="Wrap" FontSize="20" />
                          </StackPanel>
                      </DataTemplate>
                  </ItemsControl.ItemTemplate>
              </ItemsControl>

              <ItemsControl ItemsSource="{Binding Dismissals}">
                  <ItemsControl.ItemTemplate>
                      <DataTemplate>
                          <StackPanel Name="scores" Orientation="Horizontal">
                              <TextBlock Margin="0,10,0,0" Foreground="White" Text="{Binding Player}" TextWrapping="Wrap" FontSize="20" />
                              <TextBlock Margin="10,10,30,0" Foreground="White" Text="{Binding Time}" TextWrapping="Wrap" FontSize="20" />
                          </StackPanel>
                      </DataTemplate>
                  </ItemsControl.ItemTemplate>
              </ItemsControl>
          </StackPanel>
      </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>
