AutoCAD .NET输出DBObject/Entity的详细接口信息

[ 本帖最后由 csharp 于 2014-5-7 19:46 编辑 ]\n\n[ 本帖最后由 csharp 于 2014-5-7 05:32 编辑 ]\n\nUsing C# to Export Detailed Information of AutoCAD .NET DBObject/Entity

Let us look at a cool AutoCAD .NET coding gadget in this post which can export all good properties of a selected AutoCAD Entity/DBObject to a CSV file, which can be opened in the Microsoft Excel or any other CSV supported tools for us to check the detailed information for each single property. The CSV file can be reused for some other more meaningful purposes as well for sure.

In the old days without the reflection technology, this is quite a nasty task. We generally had to cast the AutoCAD generic object/entity to each available good type and access to its properties. Many short points are with this approach. The two most prominent are not efficient at all likely hundreds of even thousands of line of code have to be made and not compatible with old or new object models so likely some properties are missing in one version but some others are not available in another.

With the wonderful reflection technology handy, especially the tool classes TypeDescriptor,
PropertyDescriptor and PropertyDescriptorCollection, which are introduced in the recent .NET Framework versions, all these problems have gone away completely. We can make the same work done more nicely and professionally in just about a dozen lines of code:

    void Dump2(DBObject obj)
      string line = "Name, Value, Category, ComponentType, Description, DisplayName, IsLocalizable, IsReadOnly, PropertyType";
      using (StreamWriter sw = new StreamWriter(@"c:\temp\AcadObjectProperties.csv"))

            PropertyDescriptorCollection props = TypeDescriptor.GetProperties(obj);
            foreach (PropertyDescriptor prop in props)
                object valueObj = null;
                string valueString = string.Empty;
                  valueObj = prop.GetValue(obj);
                  if (valueObj != null)
                        valueString = valueObj.ToString();
                        valueString = valueString.Replace(",", ";");
                        line = string.Format("{0}, {1}, {2}, {3}, {4}, {5}, {6}, {7}, {8}", prop.Name, valueString, prop.Category, prop.ComponentType.Name, prop.Description, prop.DisplayName, prop.IsLocalizable, prop.IsReadOnly, prop.PropertyType.Name);
                catch (System.Exception ex)
                  if (ex.InnerException is Autodesk.AutoCAD.Runtime.Exception &&
                        (ex.InnerException as Autodesk.AutoCAD.Runtime.Exception).ErrorStatus == ErrorStatus.NotApplicable)

As can be noticed, the NotApplicable or eNotApplicable case has also been taken care of in the succinct but cool coding gadget. For the sake of convenience, the command used to test it has been appended below:

    Database db = HostApplicationServices.WorkingDatabase;
    Editor ed = MgdAcApplication.DocumentManager.MdiActiveDocument.Editor;

    public void DumpEntityInfo2_Method()
            using (Transaction tr = db.TransactionManager.StartTransaction())
                //TODO: add your code below.   
                Debug.WriteLine("DumpEntityInfo2 ran.");
                ed.WriteMessage("DumpEntityInfo2 ran.\n");

                PromptEntityResult selRes = ed.GetEntity("Pick an entity:");
                if (selRes.Status == PromptStatus.OK)
                  Entity ent = tr.GetObject(selRes.ObjectId, OpenMode.ForRead) as Entity;

      catch (System.Exception ex)

If a circle is selected for example, the content of the output CSV may look like:

Some special properties may need to be tweaked a bit further or skipped at all. I would like to leave it as an exercise to readers who have the need!

这个 Getpropertyvalue 比较全面了

这样改成命令行输出,再加工后就是 Net 版的 GetpropertyValue 了

      void Dump2(DBObject obj)
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Editor ed = doc.Editor;
            Transaction tr = doc.TransactionManager.StartTransaction();
            using (tr )
                PropertyDescriptorCollection props = TypeDescriptor.GetProperties(obj);
                foreach (PropertyDescriptor prop in props)
                  object valueObj = null;
                  string valueString = string.Empty;

                        valueObj = prop.GetValue(obj);
                        if (valueObj != null)
                            valueString = valueObj.ToString();
                            valueString = valueString.Replace(",", ";");
                            ed.WriteMessage("{0} = {1}\n", prop.Name, valueString);
                  catch (System.Exception ex)

                        if (ex.InnerException is Autodesk.AutoCAD.Runtime.Exception &&
