How to use webservice to create new object?

Hello all,

I try to use web service to create a new object in EB2022 ,but not success.I've already checked the sample code also not success, the code is below:

 public bool CreateNewObject(string DBName, string parentID, int CID, int typeID)

        {

            try

            {

                UpdateObjectDataRequest request = new UpdateObjectDataRequest();

                IList<UpdateObjectItem> items = new List<UpdateObjectItem>();

                UpdateObjectItem newItem = new UpdateObjectItem();

                newItem.CoverId = CID;

                newItem.TypeId = typeID;

                newItem.ParentId = parentID;

                newItem.UpdateMode = ObjectUpdateMode.New;

                items.Add(newItem);

                request.UpdateData = items;

                UpdateObjectDataResponse res = _proxy.UpdateObjectData(DBName, request);

                CheckResponseError(res);

                return true;

            }

            catch (Exception ex)

            {

                return false;

            }

        }

but the Error is :
[0] = Message="CID 113 is not allowed under object"; ErrorCode=-2147209611; ObjectId="00000000-0000-0000-0000-0000000C51CE"
