博客介绍了两项信息技术相关操作，一是保证有ARX，二是新建C#的类库dll，并添加ARX目录下inc文件夹中的所有dll引用，还需添加类。

1、保证有ARX

2、新建C#的类库dll；

3、添加引用（ARX目录下的inc文件夹中的所有dll）

添加类：

 public class Class1
    {
        [CommandMethod("HelloWorld")]
        public void HelloWorld()
        {
            Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
            ed.WriteMessage("Hello World");
        }

        //测试写入
        [CommandMethod("AddXRecordToEntity")]
        public void AddXRecordToEntity()
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;

            PromptEntityResult per = doc.Editor.GetEntity("\nSelect an entity: ");
            if (per.Status != PromptStatus.OK)
            {
                return;
            }

            using (Transaction tr = db.TransactionManager.StartTransaction())
            {
                Entity entity = tr.GetObject(per.ObjectId, OpenMode.ForWrite) as Entity;
                if (entity.ExtensionDictionary == ObjectId.Null)
                {
                    entity.CreateExtensionDictionary();
                }

                DBDictionary xDict = tr.GetObject(entity.ExtensionDictionary, OpenMode.ForRead) as DBDictionary;
                if (!xDict.Contains("CAXDEV"))
                {
                    xDict.UpgradeOpen();

                    Xrecord xRec = new Xrecord();
                    ResultBuffer rb = new ResultBuffer();
                    rb.Add(new TypedValue((int)DxfCode.Text, "Hello www.caxdev.com"));
                    rb.Add(new TypedValue((int)DxfCode.Int32, 123));
                    rb.Add(new TypedValue((int)DxfCode.Real, 1.2345));
                    xRec.Data = rb;
                    xDict.SetAt("CAXDEV", xRec);

                    tr.AddNewlyCreatedDBObject(xRec, true);
                }

                tr.Commit();
            }
        }
    }
