Question

我想从可用的XML数据构建WPF中的Hierarchical TreeView。这个数据可能是动态的，因此Tree可能最终会有很多级别的子节点。我的示例XML如下所示：

    <Groups>
      <Group Name="Global" ID="1">
        <Group Name="Demo - Marketing" ID="2" />
        <Group Name="Demo - Finance" ID="3" />
        <Group Name="Demo - Operations" ID="4" />
        <Group Name="Demo - Sandpit" ID="5" />
        <Group Name="Morson" ID="6">
          <Group Name="Internal" ID="29">
            <Group Name="Branch" ID="31">

如何以分层方式使用组名实现树视图？ 示例XAML和要绑定项目的类 会非常有用。 - 编程语言C＃

非常感谢提前。 -Vinnie

首先，您需要从XML模式创建类，如下所示：

[XmlRoot("Groups")]
public class GroupsXml
{
    [XmlElement("Group", typeof(Group))]
    public List<Group> GroupsList { get; set; }
}

public class Group
{
    [XmlAttribute("ID")]
    public int Id { get; set; }

    [XmlAttribute("Name")]
    public string Name{ get; set; }
}

然后，您需要将xml字符串序列化为您的案例中的对象或组列表，例如：

public List<Group> ReadGroupsFromXmlFile(string fileName)
{
    var groupsXml = new GroupsXml();
    var groupsXmlFile = xDocument.Load(fileName).ToString();
    var groupType = groupsXml .GetType();
    var oXmlSerializer = new XmlSerializer(groupType);
    groupsXml = (GroupsXml)oXmlSerializer.Deserialize(new StringReader(groupsXmlFile ));
            return categoriesXml.GroupsList;
}
