C# file name

Question

For a C# 2010 desktop application, I have a user that wants me to work with a directory path name that looks like C:\C-Received.

I am going to place the C:\C-Received in the application configuration file which is in an xml format.

I am wondering if the dash (-) that is part of the  C-Received needs to have any special characters around it since the value will be contained in an xml file?

If so, what special characters do I need to place around the '-' dash?

Also can you point me to the reference that shows which characters in an xml file need special characters around them to be recognized?
