Replacement string is
C:\\Users\\Aspose\\Test\\_Za link exchange description.doc
After I make replacement (sample project is attached, also test document) I am getting following output:
Opening document:11.10.2015 10:52:37
Document opened: 11.10.2015 10:52:37

Start document saving: 11.10.2015 10:52:37

As you can see all \ are gone.
Btw. I tried same with VB.NET and also same problem.
