How to lock a file on network (in Windows)?

Question

I'm having a service (C# service) that runs on multiple computers and share the same file (on a network storage say NAS). I want to make sure that when performing a write operation, I should be able to acquire a lock on the file, write and then unlock it.

How can I lock a file on network, when writing to it ?
