1. public static void SaveLayerColorAndLinetype()
2. {
3. document
4. Document acDoc = Application.DocumentManager.MdiActiveDocument;
6. LayerStateManager acLyrStMan;
7. acLyrStMan = acDoc.Database.LayerStateManager;
9. string sLyrStName = "ColorLinetype";
11. if (acLyrStMan.HasLayerState(sLyrStName) == false)
12. {
13. acLyrStMan.SaveLayerState(sLyrStName,
14. LayerStateMasks.Color |
15. LayerStateMasks.LineType,
16. ObjectId.Null);
17. }
18. }
19. public static void RestoreLayerState()
20. {

临时更改图层用途的时候可能会用到

不过如果正规作图很少有这种需求
