【每天一个demo】编写Hello World语句:访问ObjectARX.NET封装类

启动vs2005,新建项目，选择AutoCAD Managed c#Project模板（前提是已经安装好ObjectARX），打开Commands.cs代码。

进行编写，代码如下：

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Runtime;

[assembly: CommandClass(typeof(CsMgdAcad1.Commands))]

namespace CsMgdAcad1
{
/// <summary>
/// Summary description for Commands.
/// </summary>
public class Commands
{
public Commands()
{
//
// TODO: Add constructor logic here
//
}

// Define Command "AsdkCmd1"
[CommandMethod("helloword")]
static public void helloword() // This method can have any name
{
Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
ed.WriteMessage("Hello World,本人第一个程序");
// Put your command code here
}

}
}

生成下解决方案，然后编译下。这时会弹出autocad2007,在cad里输入命令：netload,找到CsMgdAcad1.dll该组件，然后再输入命令：helloworld，这时会显示出一个语句：Hello World,本人第一个程序，简单是简单了点。呵呵，慢慢来
