Global add prefix for existing feature definition

The below code snippet shows adding the prefix for active feature definitions used in current Dgn file. Here, " Alignment\\Geom_Baseline_Driveway" feature definition is used for demo purpose.


//Required References
using Bentley.CifNET.GeometryModel.SDK;
using Bentley.CifNET.SDK.Edit;

 public void AddPrefixToActiveFeatureDefinitions()
        {
            //Get active DGN model connection for edit purpose  
            Bentley.CifNET.SDK.Edit.ConsensusConnectionEdit con = ConsensusConnectionEdit.GetActive();
            if (con == null) return;

            //Get active geometric model
            GeometricModel activeGM = con.GetActiveGeometricModel();

            //Get Object space required for persisting the changes
            Bentley.CifNET.CadSystem.IObjectSpaceManager objectSpaceManager = Bentley.CifNET.ServiceManager.Instance.GetService<Bentley.CifNET.CadSystem.IObjectSpaceManager>();
            Bentley.CifNET.Objects.IObjectSpace objectSpace = objectSpaceManager.ObjectSpace/*.GetIsolated()*/;

            //Get active feature definitions
            foreach (Bentley.CifNET.GeometryModel.SDK.FeatureDefinition feature in activeGM.FeatureDefinitions)
            {
                //Get Object settings
                Bentley.CifNET.ContentManagementModel.ObjectSettings obs = feature.DomainObject as Bentley.CifNET.ContentManagementModel.ObjectSettings;

                if (obs.Name.Contains("Alignment\\Geom_Baseline_Driveway"))
                {
                    //Change prefix name
                    obs.NamePrefix = "GeomDW";

                    //Save changes
                    objectSpace.PersistChanges(obs);
                }
            }
        }
