Before removing the layer from the map you should disconnect it from its data source by calling IDataLayer2.Disconnect.

For files added to a map or a map control, AO keeps a lock on them even when they are removed from the map or map control.  You can try using disconnect or even call the com release on the raster but I have had more luck using IDataset.Delete and IDataset.CanDelete in those cases rather that calls to system.io.file.delete.

Very thankss for your anwers 🙂 I will use dispose() or IDataset.Delete but dont this metods .... when I called this metods only becoming Equals and ReferenceEquals.   which is .dll file missing   what do should I for it.  also I added to ESRI.Arcgis.Carto and other .dll files.
