Help with exact string match

I'm looping through the folder appA and all of its subfolders.  Some of the folders are:

c:\dev\myapps\appA\bin\release
c:\dev\myapps\appA\source
c:\dev\myapps\appA\bin\debug
c:\dev\myapps\appA\obj\appAUI
c:\dev\myapps\appA\obj\appAUI\TempPE

I set a variable that will be used as a relative path for the appA folder
Root = "appA"

Inside the loop, I may be on this folder:
paramDirectoryPath = "c:\dev\myapps\appA\obj"

and I create the relative path on each iteration this way:

paramDirectoryPath.LastIndexOf(string.Concat("\\", Root))
which gives
"\appA\obj"

It creates a relative root path for all subfolders in the appA folder.

I run into a problem when
paramDirectoryPath = "c:\dev\myapps\appA\obj\appAUI"

The LastIndexOf() code will give
"appAUI" instead of "appA".

I need to somehow get an exact, case insensitive match.  IndexOf() doesn't do this.  What is a way that I can get around that?

Thanks.  I actually ended up restructuring how this works but that's not your fault.  :)
