using (var stream = new FileStream(
                            @"C:\files\yourFile.txt", 
                            FileMode.Open, 
                            FileAccess.ReadWrite, 
                            // that's the important parameter to set
                            // it locks the file from other processes
                            // as long as the stream persists
                            FileShare.None)) {
    // give it some logic ...
