Retrieve Unix folder structure and permissions using C#

As part of building an ASP.net application, I have to display two things for a specific user on an UNIX backend system:

• the folder structure
• the folder permissions (just notation like: drwxr-xr-x).

My knowledge of communicating to UNIX with C# is, however, very limited. I've discovered a few possiblities to accomplish this:

• FTP, not sure though whether I will be able see the permissions
• SSH, seems to be most common way to interact with UNIX from C# (command ls -ld should do)
• RSH, less secure than SSH? Apart from security, what's difference with SSH开发者_如何学Go?

Questions:

• What is the best way to interact to UNIX using C#, knowing only the above two things have to be displayed?
• Perhaps some examples available somewhere (couldn't really find them yet)?

Thanks in advance.

This code project looks like it would do what you want. In fact I think the screenshot is doing exactly what you're describing.
