如何查看TimeSpan/Stopwatch.Elapsed包括秒/分钟/小时

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        Stopwatch stopwatch = new Stopwatch();
        stopwatch.Start();

        // 模拟一些操作
        System.Threading.Thread.Sleep(2000);

        stopwatch.Stop();

        TimeSpan elapsed = stopwatch.Elapsed;
        double totalSeconds = elapsed.TotalSeconds;
        double totalMinutes = elapsed.TotalMinutes;
        double totalHours = elapsed.TotalHours;

        Console.WriteLine("总秒数: " + totalSeconds);
        Console.WriteLine("总分钟数: " + totalMinutes);
        Console.WriteLine("总小时数: " + totalHours);
    }
}
