Emgu CV在WPF项目中缺少ImageBox的上下文菜单？

using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;

namespace YourNamespace
{
    public class CustomImageBox : Image
    {
        public CustomImageBox()
        {
            // 添加上下文菜单
            ContextMenu = new ContextMenu();

            // 添加菜单项
            MenuItem menuItem = new MenuItem();
            menuItem.Header = "菜单项1";
            menuItem.Click += MenuItem_Click;
            ContextMenu.Items.Add(menuItem);

            // 添加更多菜单项...

            // 监听鼠标右键点击事件，显示上下文菜单
            MouseRightButtonDown += CustomImageBox_MouseRightButtonDown;
        }

        private void CustomImageBox_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
        {
            ContextMenu.IsOpen = true;
        }

        private void MenuItem_Click(object sender, RoutedEventArgs e)
        {
            // 处理菜单项点击事件
            // 在这里可以编写相应的逻辑代码
        }
    }
}
