How do I move DynamicBlock to a BlockTableRecord,and ensure thatthe result is not an anonymous block?
I try deepclone,but show error eAlreadyIrDb,how to transform to BlockTableRecord.thank you eyeryone for here.

 var ent = (Entity)tr.GetObject(item);
 Entity clonedEntity;
 if (ent is BlockReference br && br.IsDynamicBlock)
 {
     //using ObjectIdCollection mapIds = [br.ObjectId];
     //using IdMapping mapping = [];
     //Env.Database.DeepCloneObjects(mapIds, Env.Database.CurrentSpaceId, mapping, false);
     //clonedEntity = (Entity)tr.GetObject(mapping[br.ObjectId].Value, OpenMode.ForWrite);
     var clonedDynamicBlock = (BlockReference)ent.Clone();
     CopyDynamicProperties(br, clonedDynamicBlock, Env.Editor);
     clonedEntity = clonedDynamicBlock;
 }
 else
     clonedEntity = (Entity)ent.Clone();

 btr.AppendEntity(clonedEntity);

It is a bit hard to understand what you want to do: "...move to..." which/what BlockTableRecord? What does CopyDynamicProperies() method do? 

If you want to convert a dynamic blockreference (with its dynamic properties are properly set) to a non-anonymous block reference, you may want to try BlockReference.ConvertToStaticBlock() method, which will turn the dyanmic blockreference into a static blockreference.

To copy a dynamic block to another owner, you use DeepCloneObjects() and specify the new owner BlockTableRecord as the owner argument. 

There is no other way to copy a dynamic block reference (including Clone()), because it requires translation of ObjectIds that can only be done by DeepClone.

I solved the problem, the above may not have clearly described the requirements, resulting in ambiguity. The second parameter in the following line of code is btrId, thank you for your answer to give me ideas.

db.DeepCloneObjects(needAddIds, btrId, mapping, false);
