C# location of file in ditectory structure

Question

In a C# 2008 windows application, I planning on locating files that I need to find by utilizing the following code:

var RFiles = from path in Directory.EnumerateFiles(filesaveLocation, "*.*",
SearchOption.AllDirectories)
  let extension = Path.GetExtension(path)
  where extension == ".pdf" || extension == ".xlsx" || extension == ".xls"
  select path;

However once I find each selected file, I need to know the exact location of where each specified file was located. I need to be able to store the exact directory structure location in a sql server 2008 r2 database.

Basically the code statement would be similar to tell me exactly where each seelcted file  is located at.

Thus can you me in code and/or explain to me how to accomplish my goal?
