C#检查一段代码的消耗时间

System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch();
        stopwatch.Start();

        //这里是你想检测的时间

        stopwatch.Stop();
        System.TimeSpan timeSpan = stopwatch.Elapsed;
        double hours = timeSpan.TotalHours;
        double minutes = timeSpan.TotalMinutes;
        double seconds = timeSpan.TotalSeconds;
        double milliseconds = timeSpan.TotalMilliseconds;


        Debug.Log("总小时:" + hours);
        Debug.Log("总分钟:" + minutes);
        Debug.Log("总秒:" + seconds);
        Debug.Log("总毫秒:" + milliseconds);
