WblockCloneObjects memory not
Hi,i need to read an external dwg and import only some entities.
I use WblockCloneObjects, it work fine but i found a memory problem, the memory is not disposed autocad memory process significantly increases after every WblockCloneObjects.
Where is the problem?
Thank you very much.
public void TestClone() { // repeated 20 times to highlight the memory consumption for (int i = 0; i < 20; i++) { ObjectIdCollection filteredIds = new ObjectIdCollection(); Database targetDb = ACAP.Application.DocumentManager.MdiActiveDocument.Database; using (Transaction trMain = targetDb.TransactionManager.StartTransaction()) { using (Database db = new Database(false, true)) { // read the source dwg db.ReadDwgFile(@"D:\he10t.dwg", FileOpenMode.OpenForReadAndAllShare, true, ""); // get all entities using (Transaction trSource = db.TransactionManager.StartTransaction()) { BlockTable pBT = (BlockTable)trSource.GetObject(db.BlockTableId, OpenMode.ForRead, false); BlockTableRecord pBTR = (BlockTableRecord)trSource.GetObject(pBT, OpenMode.ForRead, false); foreach (ObjectId id in pBTR) { // ...open entity and filter filteredIds.Add(id); } } // clone the filtered entities in current document using (ACAP.DocumentLock dl = ACAP.Application.DocumentManager.MdiActiveDocument.LockDocument()) { using (IdMapping mapping = new IdMapping()) { // now clone the objects into the destdb ObjectId destDbMsId = SymbolUtilityServices.GetBlockModelSpaceId(targetDb); db.WblockCloneObjects(filteredIds, destDbMsId, mapping, DuplicateRecordCloning.Replace, false); } } } trMain.Commit(); } filteredIds.Dispose(); } }
