C# Subtrct 경과시간

Remark : 경과 시간 계산 하기

1,TimeSpan 사용


static void Main(string[] args)
{
	DateTime dStart = DateTime.Now;
	Thread.Sleep(2000);
	
	TimeSpan SpanGap = DateTime.Now - dStart;

	TimeSpan SpanGapSecond = new TimeSpan(SpanGap.Hours, SpanGap.Minutes, SpanGap.Seconds, 0);

	Console.WriteLine("{0}", SpanGapSecond.ToString());

	//00:00:02.113456
	Console.ReadLine();
}

static void Main(string[] args)

{

DateTime dStart = DateTime.Now;

Thread.Sleep(2000);

TimeSpan SpanGap = DateTime.Now - dStart;

TimeSpan SpanGapSecond = new TimeSpan(SpanGap.Hours, SpanGap.Minutes, SpanGap.Seconds, 0);

Console.WriteLine("{0}", SpanGapSecond.ToString());

//00:00:02.113456

Console.ReadLine();

}

2.Stopwatch 사용/ 버전에 상관없이 쓸수 있는 방식 (추천)


static void Main(string[] args)
{
	var timer = System.Diagnostics.Stopwatch.StartNew();
	// sleep for 1.5s
	Thread.Sleep(1500);
	timer.Stop();
	var elapsed = timer.Elapsed;

	Console.WriteLine(elapsed.ToString("mm':'ss':'fff"));

	//00:00:01.504
	Console.ReadLine();
}

static void Main(string[] args)

{

var timer = System.Diagnostics.Stopwatch.StartNew();

// sleep for 1.5s

Thread.Sleep(1500);

timer.Stop();

var elapsed = timer.Elapsed;

Console.WriteLine(elapsed.ToString("mm':'ss':'fff"));

//00:00:01.504

Console.ReadLine();

}
