How show minutes and seconds with Stopwatch()

I need to show also the minutes, actually I use this code for show the seconds, but also need the minutes

TimeSpan ts = stopwatch.Elapsed;
Console.WriteLine("File Generated: " + _writer.getBinaryFileName(filePath, Convert.ToInt32(logSelected)) + " in "  + "{0}.{1:D2}" + "seconds", 
    ts.Seconds, 
    ts.Milliseconds/10 + "\n"
);

how can I do?
