wpf五级地址选择控件

WPF中没有内置的五级地址选择控件，但可以使用TreeView或ComboBox等控件来实现。以下是一个简单的实现方式：

1. 创建一个继承自TreeViewItem的类，用于表示地址节点；

2. 创建一个继承自TreeView的控件，用于显示地址树；

3. 在控件中添加五个ComboBox控件，分别用于选择省、市、区、街道和小区；

4. 在ComboBox的SelectionChanged事件中，根据选择的项更新地址节点的子节点和父节点；

5. 将地址节点添加到TreeView中，以构建地址树。

下面是一个简单的示例代码：

public class AddressNode : TreeViewItem
{
    public string Name { get; set; }
    public AddressNode() { }
    public AddressNode(string name) { Name = name; }
}

public class AddressTreeView : TreeView
{
    private ComboBox _provinceBox;
    private ComboBox _cityBox;
    private ComboBox _districtBox;
    private ComboBox _streetBox;
    private ComboBox _communityBox;

    public AddressTreeView()
    {
        _provinceBox = new ComboBox();
        _provinceBox.SelectionChanged += OnProvinceSelectionChanged;

        _cityBox = new ComboBox();
        _cityBox.SelectionChanged += OnCitySelectionChanged;

        _districtBox = new ComboBox();
        _districtBox.SelectionChanged += OnDistrictSelectionChanged;

        _streetBox = new ComboBox();
        _streetBox.SelectionChanged += OnStreetSelectionChanged;

        _communityBox = new ComboBox();
        _communityBox.SelectionChanged += OnCommunitySelectionChanged;

        var stackPanel = new StackPanel();
        stackPanel.Children.Add(_provinceBox);
        stackPanel.Children.Add(_cityBox);
        stackPanel.Children.Add(_districtBox);
        stackPanel.Children.Add(_streetBox);
        stackPanel.Children.Add(_communityBox);

        var rootNode = new AddressNode();
        Items.Add(rootNode);
    }

    private void OnProvinceSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        // TODO: update city nodes
    }

    private void OnCitySelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        // TODO: update district nodes
    }

    private void OnDistrictSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        // TODO: update street nodes
    }

    private void OnStreetSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        // TODO: update community nodes
    }

    private void OnCommunitySelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        // TODO: update address
    }
}
