设置透明度的方法2.

核心代码同上文。

public bool SetDiaphaneity(double Mdiaphaneity, ObjectId[] EntityId)
        {

            bool setBool = false;

            Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;

            using (DocumentLock docLock = Application.DocumentManager.MdiActiveDocument.LockDocument())
            {

                using (Database db = HostApplicationServices.WorkingDatabase)
                {
                    try
                    {

                        using (Transaction trans = db.TransactionManager.StartTransaction())
                        {

                            AddMaterial(Mdiaphaneity, "wood");

                            foreach (ObjectId obi in EntityId)
                            {

                                Entity ent = trans.GetObject(obi, OpenMode.ForWrite) as Entity;

                                ent.Material = "wood";

                                this.Dispose(ent);
                            }

                            trans.Commit();

                            setBool = true;
                        }
                    }
                    finally
                    {

                        this.Dispose(db);
                    }
                }
            }

            return setBool;
        }
