using Autodesk.AutoCAD.EditorInput;
[assembly: CommandClass(typeof(HelloWorld.Hello))] namespace HelloWorld {
///
/// Summary description for rdsCommands. /// public class Hello {

// TODO: Add constructor logic here // }
// Define Command \ [CommandMethod(\)]
static public void HW() // This method can have any name {
// Put your command code here
Editor pEd = Application.DocumentManager.MdiActiveDocument.Editor; pEd.WriteMessage(\); } } }
→编译，并在AutoCAD加载DLL

→输入命令“HW”，查看运行结果
4.4 创建上下文菜单 （1）加载命名空间
? using System;
? using Autodesk.AutoCAD.Runtime; ? using Autodesk.AutoCAD.Windows; ? using Autodesk.AutoCAD.EditorInput; （2）输入完成程序如下
using System;
using Autodesk.AutoCAD.Windows; using Autodesk.AutoCAD.Runtime; using Autodesk.AutoCAD.EditorInput;
[assembly: CommandClass(typeof(MyMenu.MyMenu))] namespace MyMenu {
public class MyMenu : IExtensionApplication {
ContextMenuExtension MyMenu; //初始化菜单
public void Initialize() {
AddMenu(); }
//释放资源，移除菜单 public void Terminate() {
Remove(); }
//添加菜单
public void AddMenu() { try {
MyMenu = new ContextMenuExtension();
6
MyMenu.Title = \;
Autodesk.AutoCAD.Windows.MenuItem menuItem;
menuItem = new Autodesk.AutoCAD.Windows.MenuItem(\); menuItem.Click += new EventHandler(CallbackOnClick); MyMenu.MenuItems.Add(menuItem);
Autodesk.AutoCAD.ApplicationServices.Application. AddDefaultContextMenuExtension(MyMenu); }
catch (System.Exception ex){} }
//移除菜单
public void Remove() { try {
if (MyMenu != null) {
Autodesk.AutoCAD.ApplicationServices.Application. RemoveDefaultContextMenuExtension(MyMenu); } }
catch (System.Exception ex){} }
public void CallbackOnClick(object sender, EventArgs e){} } }
（3）编译，并在AutoCAD利用NETLOAD加载dll。
4.5 创建弹出式下拉菜单 （1）输入完整程序如下：

using System.Threading.Tasks; using System.IO;
using Autodesk.AutoCAD.Customization; using Autodesk.AutoCAD.ApplicationServices;

private void addMenu2Workspaces(PopMenu pm) {}
private void save_Cui() {
