I'm working on being able to serialize C# objects to AutoCAD entities. I have a method that serializes them and I'm trying to call this method from the AutoCAD command line intended to deserialize them.
[CommandMethod("OpenXRecord", CommandFlags.Modal)] public SerializeTest XMLOpen() { Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; Editor ed = doc.Editor; Database db = doc.Database; SerializeTest retval = null; XmlSerializer serializer = new XmlSerializer(typeof(SerializeTest)); using (Transaction tr = db.TransactionManager.StartTransaction()) using (DocumentLock docLock = doc.LockDocument()) { PromptSelectionResult acSSPrompt = ed.GetSelection(); if (acSSPrompt.Status == PromptStatus.OK) { ObjectId[] ids = acSSPrompt.Value.GetObjectIds(); Entity acadObj = tr.GetObject(ids[0], OpenMode.ForWrite) as Entity; if (acadObj == null || acadObj.ExtensionDictionary == ObjectId.Null) { tr.Abort(); return retval; } using (DBDictionary dict = tr.GetObject(acadObj.ExtensionDictionary, OpenMode.ForRead, false) as DBDictionary) { if (dict.Contains("KW_PID")) { using (Xrecord xrec = tr.GetObject(dict.GetAt("KW_PID"), OpenMode.ForRead) as Xrecord) { if (xrec != null) { using (ResultBuffer rb = xrec.Data) { if (rb != null) { using (MemoryStream stream = new MemoryStream()) { TypedValue[] tvs = rb.AsArray(); if (tvs != null) { if (tvs[0].TypeCode == (short)DxfCode.Text) { string xmlString = ""; TextWriter writer = new StreamWriter(stream); for (int i = 1; i < tvs.Length; i++) { if (tvs[i].TypeCode == (short)DxfCode.Text) { xmlString = (string)tvs[i].Value; writer.Write(xmlString); } } writer.Flush(); stream.Position = 0; retval = serializer.Deserialize(stream) as SerializeTest; } } } } } } } } } } } return retval; }
However, when I call it, I'm greeted with this error and have no idea why as it gives no line numbers or useful debug information.
