WPF 仿照ElementUI实现时间选择器（TimePicker）

在WPF中，要实现类似ElementUI的时间选择器(TimePicker)，你可以使用自定义控件或现有的第三方库。以下是一个简单的自定义时间选择器的例子：

1. 创建一个新的WPF用户控件（UserControl）。
2. 向用户控件中添加两个ComboBox来分别选择小时和分钟。
3. 绑定数据到ComboBox并实现交互。

这是一个基本的实现示例：

<UserControl x:Class="WpfTimePicker.TimePickerControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             Width="120" Height="30">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="Auto"/>
        </Grid.ColumnDefinitions>
        <TextBlock Text="Hour" VerticalAlignment="Center" Margin="5,0"/>
        <ComboBox x:Name="HourComboBox" Width="50" Margin="5,0" Grid.Column="1"/>
        <TextBlock Text=":" VerticalAlignment="Center" Grid.Column="2"/>
        <ComboBox x:Name="MinuteComboBox" Width="50" Margin="5,0" Grid.Column="3"/>
    </Grid>
</UserControl>

using System;
using System.Windows.Controls;
 
namespace WpfTimePicker
{
    public partial class TimePickerControl : UserControl
    {
        public TimePickerControl()
        {
            InitializeComponent();
            InitializeHourComboBox();
            InitializeMinuteComboBox();
        }
 
        private void InitializeHourComboBox()
        {
            for (int i = 0; i < 24; i++)
            {
                HourComboBox.Items.Add($"{i:D2}");
            }
            HourComboBox.SelectedIndex = 0;
            HourComboBox.SelectionChanged += HourComboBox_SelectionChanged;
        }
 
        private void InitializeMinuteComboBox()
        {
            for (int i = 0; i < 60; i++)
            {
                MinuteComboBox.Items.Add($"{i:D2}");
            }
            MinuteComboBox.SelectedIndex = 0;
        }
 
        private void HourComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            // Update MinuteComboBox if needed
        }
 
        public DateTime SelectedTime
        {
            get
            {
                int hour = int.Parse(HourComboBox.SelectedItem.ToString().Substring(0, 2));
                int minute = int.Parse(MinuteComboBox.SelectedItem.ToString().Substring(0, 2));
                return new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, hour, minute,
