Had a terrible time getting this to work to retrieve a BITMAP object from a HBITMAP, this code finally worked.

BITMAP bmpScreen;

GCHandle hndl = GCHandle.Alloc(bmpScreen, GCHandleType.Pinned);

IntPtr ptrToBitmap = hndl.AddrOfPinnedObject();

GDI32.GetObject(hBitmap, Marshal.SizeOf<GDI32.BITMAP>(), ptrToBitmap);

bmpScreen = Marshal.PtrToStructure<GDI32.BITMAP>(ptrToBitmap);

hndl.Free();
