用C#开发AutoCAD新手求救

我想实现如下功能：在AutoCAD上创建自己的菜单，菜单标签下有自己的按钮。我从网上抄了一段代码，创建了一个WPF自定义控件，代码如下：
using System;
using System.Collections.Generic;
using System.Text;
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;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.Windows;
namespace WpfCustomControlLibrary3
{
    
    public class CustomControl1 : Control
    {
        [CommandMethod("test")]
        void test()
        {
            //创建一个按钮
       RibbonButton button = new RibbonButton();
            button.Text = "ClickMe";
            button.Orientation = Orientation.Vertical;
            button.Size = RibbonItemSize.Large;
            button.Id = "ClickMe_1";            //创建RibbonRow用来放置按钮
       RibbonRow row = new RibbonRow();
            row.Items.Add(button);            //创建RibbonPanelSource,用来放置RibbonRow
            RibbonPanelSource panelSource = new RibbonPanelSource();
            panelSource.Title = "Custom Panel";
            panelSource.Rows.Add(row);            //再创建一个RibbonPanel来放置上面的RibbonSource
            RibbonPanel panel = new RibbonPanel();
            panel.Source = panelSource;            //创建AutoCAD菜单标签，放置RibbonPanel
            RibbonTab tab = new RibbonTab();
            tab.Title = "Custom Tab";
            tab.IsContextualTab = false;
            tab.Panels.Add(panel);            //RibbonControl是所有AutoCAD控制按钮的基础
            RibbonControl ribbonControl =    Autodesk.AutoCAD.Ribbon.RibbonServices.RibbonPaletteSet.RibbonControl;
            ribbonControl.Tabs.Add(tab);            //激活标签，响应事件
       ribbonControl.ActiveTab = tab;
            button.Click += new RoutedEventHandler(button_Click);
        }        private static void button_Click(Object sender, RoutedEventArgs e)
        {
            RibbonButton button = sender as RibbonButton;
            if (button != null && (button.Id == "ClickMe_1"))
            {
                MessageBox.Show("click");
                e.Handled = true;
            }
        }
        static CustomControl1()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl1), new FrameworkPropertyMetadata(typeof(CustomControl1)));
        }
    }
}
调试用的是AutoCAD2010版，但是输入test命令提示未知命令，请哪位高手指教
