Question

是否可以在WPF TreeView中显示（自定义）详细信息？

我想显示计算机的所有服务，并在其旁边显示“描述”，“状态”等，并能够在扩展时订购它。有可能实现吗？

我正在以编程方式创建树，这是我到目前为止所拥有的：

    public void LoadServices(object sender, RoutedEventArgs e)
    {
        TreeView.Items.Clear();
        List<string> computers = new List<string> { Environment.MachineName, Environment.MachineName };
        foreach (string computer in computers)
        {
            TreeViewItem CurrComputer = new TreeViewItem { Header = computer };
            TreeView.Items.Add(CurrComputer);
            Services = ServiceController.GetServices();

            foreach (ServiceController tempService in Services)
            {
                TreeViewItem newService = new TreeViewItem
                {
                    Header = tempService.DisplayName
                };
                CurrComputer.Items.Add(newService);
            }
        }
    }

/ edit：我能想到的一种解决方案是在其旁边放置一个列表视图，并将其从树视图映射到列表视图。但这并不是很顺利，也意味着如果我按某种顺序排序，则树形视图将不会被排序。

这是我正在使用的解决方案：建议您使用ObservableCollection编写最少的编码

MainWindows.xaml：

<Window x:Class="zzWpfApp2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:zzWpfApp2"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid Margin="10">
        <TreeView Name="trvMenu">
            <TreeView.ItemTemplate>
                <HierarchicalDataTemplate DataType="{x:Type MenuItem}" ItemsSource="{Binding Items}">
                    <TextBlock Text="{Binding Title}" />
                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>
    </Grid>
</Window>

MainWindow.xaml.cs

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ServiceProcess;
using System.Windows;

namespace zzWpfApp2
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            List<string> computers = new List<string> { Environment.MachineName, Environment.MachineName };
            MenuItem root = new MenuItem() { Title = "General Menu" };

            foreach (string computer in computers)
            {
                MenuItem childItem = new MenuItem() { Title = computer };

                foreach (ServiceController tempService in ServiceController.GetServices())
                {
                    childItem.Items.Add(new MenuItem() { Title = tempService.DisplayName });
                }
                root.Items.Add(childItem);
            }
            trvMenu.Items.Add(root);
        }
        public class MenuItem
        {
            public MenuItem()
            {
                this.Items = new ObservableCollection<MenuItem>();
            }

            public string Title { get; set; }

            public ObservableCollection<MenuItem> Items { get; set; }
        }
    }
}

和结果：

如果您想了解更多信息，请修改循环：

            foreach (ServiceController tempService in ServiceController.GetServices())
            {
                MenuItem subchildItem = new MenuItem() {Title = tempService.DisplayName };                 
                childItem.Items.Add(subchildItem);
                subchildItem.Items.Add(new MenuItem() { Title = tempService.Status.ToString()});
                subchildItem.Items.Add(new MenuItem() { Title = tempService.ServiceName});
            }
