c# - 将 XML 文件显示到列表框中

Question

我是 WPF/C# 编程的新手。我正在尝试使用此 XAML 代码将 xml 文件内容显示到列表框中:

<Window x:Class="test.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <XmlDataProvider x:Key="HostsData"
                   Source="/Hosts.xml"
                   XPath="Hosts/Host" />
    </Window.Resources>
    <Grid>
        <ListBox Height="100" HorizontalAlignment="Left" Margin="98,70,0,0" Name="listBox1"
                 VerticalAlignment="Top" Width="120" SelectionChanged="listBox1_SelectionChanged"
                 ItemsSource="{Binding Source={StaticResource HostsData}}"
                 DisplayMemberPath="HostName"/>
    </Grid>
</Window>

Hosts.xml 包含:

<Hosts>
  <Host>
    <IP>1.1.1.1</IP>
    <HostName>abc01</HostName>
  </Host>
  <Host>
    <IP>2.2.2.2</IP>
    <HostName>abc02</HostName>
  </Host>
</Hosts>

我构建成功，但是当我运行应用程序时，列表框是空的!我已将 Hosts.xml 文件复制到各处，但仍然没有。

有什么想法吗？

我试过这样....看看

<Window x:Class="WpfApplication2.Window4"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window4" Height="300" Width="300">
<Window.Resources>
    <XmlDataProvider x:Key="BookmarkData" XPath="Hosts/Host">
        <x:XData>
            <Hosts>
                <Host>
                    <IP>1.1.1.1</IP>
                    <HostName>abc01</HostName>
                </Host>
                <Host>
                    <IP>2.2.2.2</IP>
                    <HostName>abc02</HostName>
                </Host>
            </Hosts>
        </x:XData>
    </XmlDataProvider>
</Window.Resources>
  <Grid>
    <ListBox
           Background="#999"
           BorderThickness="2"
           BorderBrush="White" 
           Margin="10"
           DisplayMemberPath="HostName" 
           ItemsSource="{Binding Source={StaticResource BookmarkData}, XPath=/Hosts/Host}"
           />

</Grid>
