Getting List Internal Name

Hi Guys,
I ran into a very wierd but intresting issue today. The client changed the document library name and suddenly even handler started throwing error saying the file path does not matched. Whenever the list name changes, the internal name remains same and the path of the file remains with the internal name. So my properties.ListTitle was picking the display name and could not find the file.

So always better approach is to use list internal name.
Not simple but not even complex:
I used

properties.ListItem.ListItems.List.RootFolder.Name

and it gave me the list internal name and the issue was fixed. Cheers!

So, the basic logic is that, if you want to use list internal name, then you have to follow

objList.RootFolder.Name
