C# .NET - how to use filesystemwatcher over network for sharedfolder

Hi,
     I need to monitor the shared folder by using filesystemwatcher, if any modification in the folder i like to update file in local folder. Please give the solution  filesystemwatcher for networkfolder(how to monitor folder if any shared folder connection lose) or sample code or project.

The MSDN documentation states that you can use the FileSystemWatcher class to monitor changes on a network drive.
See here:

Hi peter,

           How to check the filesystemwatcher is disconnected or connected on shared folder monitoring. Please give solution for this and how to reboot the filesystemwatcher to monitor the folder

The FileSystemWatcher is a class. When instantiated, it starts monitoring and doesn't stop until the instantiated object is disposed. You can find numerous examples of code that uses this with a simple google search. One common usage is to have this run inside a custom Windows Service that you write.
