        Lock files so that no one else can access it:
 string filename = "c:\\sample.htm";
 FileStream stream = new FileStream(filename, FileMode.Open, FileAccess.Read, 
 FileShare.None); //locks file


 stream.Close(); //unlocks file
 string filename = "c:\\sample.htm";
 FileStream stream = File.Open(filename, FileMode.Open);
 stream.Lock(0, stream.Length); //locks file


 stream.Unlock(0, stream.Length); //unlocks file
