i wan't cocy entity between two different database, But i can't find the entity in the new database?

            string drawingPath = @"E:\2017\aa.dwg";

            Database destDb = Application.DocumentManager.MdiActiveDocument.Database;
            Database sourceDb = new Database(false, true);
            sourceDb.ReadDwgFile(drawingPath, System.IO.FileShare.Read, false, null);
            var SourceObjectIds = new ObjectIdCollection();
            Autodesk.AutoCAD.DatabaseServices.TransactionManager SourceTm = sourceDb.TransactionManager;


            using (Transaction extTrans = sourceDb.TransactionManager.StartTransaction())
            {
                BlockTable extBlockTable = (BlockTable)extTrans.GetObject(sourceDb.BlockTableId, OpenMode.ForRead);
                BlockTableRecord  extModelSpace = (BlockTableRecord)extTrans.GetObject(extBlockTable[BlockTableRecord.ModelSpace], OpenMode.ForRead);
                foreach (ObjectId id in extModelSpace)
                {
                    SourceObjectIds.Add(id);


                }


                extTrans.Commit();
            }
            sourceDb.CloseInput(true);

            using (Transaction acTrans = destDb.TransactionManager.StartTransaction())
            {
                BlockTable acBlkTbNewDoc = acTrans.GetObject(destDb.BlockTableId, OpenMode.ForRead) as BlockTable;
                BlockTableRecord acBlkRecNewdoc = acTrans.GetObject(acBlkTbNewDoc[BlockTableRecord.ModelSpace], OpenMode.ForRead) as BlockTableRecord;


                IdMapping acIdMap = new IdMapping();
                destDb.WblockCloneObjects(SourceObjectIds, acBlkTbNewDoc.ObjectId, acIdMap, DuplicateRecordCloning.Ignore, false);
                acTrans.Commit();

            }

what's wrong? i use the autocad 2010

            ...

            using (Transaction acTrans = destDb.TransactionManager.StartTransaction())
            {
                BlockTable acBlkTbNewDoc = acTrans.GetObject(destDb.BlockTableId, OpenMode.ForRead) as BlockTable;
                BlockTableRecord acBlkRecNewdoc = acTrans.GetObject(acBlkTbNewDoc[BlockTableRecord.ModelSpace], OpenMode.ForRead) as BlockTableRecord;


                IdMapping acIdMap = new IdMapping();
                destDb.WblockCloneObjects(SourceObjectIds, acBlkTbNewDoc.ObjectId, acIdMap, DuplicateRecordCloning.Ignore, false);
                acTrans.Commit();

            }

I assume you want to copy all entities from source drawing's ModelSpace to destination drawing's ModelSpace. Look at the second parameter you passed to WBlockCloneObjects() method (in red): you obviously passed wrong Id - BlockTable's Id, instead of ModelSpace BlockTableRecord's Id.
