How to select a object  in one drawing and pass to another drawing?


            Dim acadDoc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument
            Dim db As Database = acadDoc.Database
            Dim ed As Editor = acadDoc.Editor

            Dim peo As New PromptEntityOptions(vbLf & "Select source block reference: ")
            peo.SetRejectMessage(vbLf & "Entity is not a block.")
            peo.AddAllowedClass(GetType(BlockReference), False)

            Dim per As PromptEntityResult = ed.GetEntity(peo)

            If per.Status <> PromptStatus.OK Then
                Return
            End If

If you're just trying to copy objects from one dwg to another look at WblockCloneObjects.

Try this quick example, just change file name and block name to your suit,
I didn't test this code on dynamic block though


--- Code: ---       [CommandMethod("copyblock", CommandFlags.Session | CommandFlags.Modal)]
        public static void DynBlockCopyTest()
        {
            ObjectId btrid = ObjectId.Null;
            // set full path of container file, block name
            InsertDynBlockFromFile(@"C:\Test\WorkingDrawing.dwg", "IMP");
        }



        public static void InsertDynBlockFromFile(string sourcefile, string blkName)
        {

            ObjectIdCollection ids = new ObjectIdCollection();

            // Find the file containing all the blocks

            if (!File.Exists(sourcefile))
            {
                MessageBox.Show("Could not find file !");

                return;

            }

            DocumentCollection dm = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager;

            ObjectId sourceid = ObjectId.Null;

            Document doc = dm.MdiActiveDocument;

            Database db = doc.Database;

            Editor ed = doc.Editor;

            try
            {

                Document sourcedoc = dm.Open(sourcefile, false);

                // Needed for source document since the source database has to be active.

                dm.MdiActiveDocument = sourcedoc;

                Editor sourced = sourcedoc.Editor;

                Database sourcedb = sourcedoc.Database;

                PromptEntityOptions peo = new PromptEntityOptions("\nSelect dynamic block: ");

                peo.SetRejectMessage("\nMight be of type BlockReference");

                peo.AddAllowedClass(typeof(BlockReference), true);

                PromptEntityResult res = sourced.GetEntity(peo);

                if (res.Status != PromptStatus.OK) return;

                using (Transaction sourcetr = sourcedb.TransactionManager.StartTransaction())
                {
                    BlockTable sourcebt = null;

                    sourcebt = sourcetr.GetObject(sourcedb.BlockTableId, OpenMode.ForRead) as BlockTable;

                    if (!sourcebt.Has(blkName))
                    {
                        MessageBox.Show("Block not found !");

                        return;

                    }

                    // Find the ObjectId of the block we are interested in.

                    sourceid = res.ObjectId;

                    ids.Add(sourceid);

                }


                using (DocumentLock doclock = doc.LockDocument())
                {
                   
                    using (Transaction tr = db.TransactionManager.StartTransaction())
                    {

                        destbt = tr.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable;

                        BlockTableRecord destbtr = null;

                        ObjectId destbtrid = destbt[BlockTableRecord.ModelSpace];

                        destbtr = tr.GetObject(destbtrid, OpenMode.ForWrite) as BlockTableRecord;

                        // WBlockClone the BlockTable record to the current database

                        // Needed for document since the destination database has to be active.

                        // ObjectId of the btr that we want to clone

                        IdMapping idmap = new IdMapping();

                        db.WblockCloneObjects(ids, destbtrid, idmap, DuplicateRecordCloning.Ignore, false);

                        // Here you may want to get inserted block and modify its properies and attributes

                        // Close source file without changes

                        sourcedoc.CloseAndDiscard();

                        tr.Commit();
                    }

                }
            }

            catch (System.Exception ex)

                Autodesk.AutoCAD.ApplicationServices.Application.ShowAlertDialog(string.Format("\n{0}\n{1}", ex.Message, ex.StackTrace));
