DriveInfo Class

How to I execute the following code in silverlight 3.

    DriveInfo[] drives = DriveInfo.GetDrives();        
    foreach (DriveInfo drive in drives)
    {
       if (drive.IsReady)
       { }   
    }

As it is giving me error and when I try to add the reference for the system.IO I can't fine any reference for that Dll.Thanks in advance

Silverlight is executing in the browser, and can execute on platforms as diverse as Windows, OSX, Linux, etc.

I'd be really surprised is something as low-level as drive info would operate as it would on a Windows native forms app.
