Accessing a network file share with C#

Accessing a network file share with C#

I've never done this before, and all of the research I've done indicates
needing user names/passwords. Here's the situation: I am developing an app
for my company, and the app needs to access a file share on the network.
Let's call that file share \\server\TPK. My app needs to get files from
this folder on this share. Is working with file shares on a company
network the same as working with File I/O (System.IO)? Can anyone give me
any guidance on how to do this? I know this probably is an elementary
question, and I apologize for that.
