Is there a way to learn the username of the user that has a file open?

I am developing a program that will be a desktop client for many users. The application will open some files and I'd like to allow many users to open the files at the same time, but only allow the first user to have write privileges. What I want is to be able to tell the other users who has write access to a file.

Is that something that can be learned by an application? (I am developing in VS 2008).

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
