 效果图如上所示:

前端Xmal代码:

Window x:Class="WpfTest.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:WpfTest"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    Grid>
        StackPanel>
            Button Content="www.wikibt.com"  Click="Button_Click">Button>

            ComboBox ItemsSource="{Binding Items}" SelectedItem="{Binding CurrentItem}">
                ComboBox.ItemTemplate>
                    DataTemplate>
                        StackPanel Orientation="Horizontal">
                            Image Source="/images/www.wikibt.com.png">Image>//此处图片路径写死了,可以用绑定实现不一样的图片{Binding ItemImage}
                            TextBlock Text="{Binding ItemName}" VerticalAlignment="Center" HorizontalAlignment="Center">TextBlock>
                        StackPanel>
                    DataTemplate>
                ComboBox.ItemTemplate>
            ComboBox>
        StackPanel>
    Grid>
Window>

后端代码:

using RevitTask;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfTest
{
    /// 
    /// MainWindow.xaml 的交互逻辑
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Items = new List() {
                new ImageItem("",1),new ImageItem("",2),new ImageItem("",3)
            };
            this.DataContext = this;
        }

        public List Items { get; set; }
        public ImageItem CurrentItem { get; set; }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show(CurrentItem == null ? "null" : CurrentItem.ItemValue.ToString());
        }
    }
    public class ImageItem
    {
        public ImageItem(string name, object value)
        {
            ItemName = name;
            ItemValue = value;
        }
        public ImageItem(string name, object value, ImageSource img) : this(name, value)
        {
            ItemImage = img;
        }
        public string ItemName { get; set; }
        public object ItemValue { get; set; }
        public ImageSource ItemImage { get; set; }
    }
}
