計算時間差C#版

protected string GetDiffTime(DateTime beginTime, DateTime endTime)<br /> {<br /> string strResout = "{0}{1}前";<br /> //獲得2時間的時間間隔秒計算<br /> TimeSpan span = endTime - beginTime;<br /> int iTatol = Convert.ToInt32(span.TotalSeconds);</p><p> int iMinutes = 1 * 60;<br /> int iHours = iMinutes * 60;<br /> int iDay = iHours * 24;<br /> int iMonth = iDay * 30;<br /> int iYear = iMonth * 12;</p><p> if (iTatol>iYear)<br /> {<br /> return string.Format(strResout, iTatol / iYear,"年");<br /> }<br /> else if (iTatol > iMonth)<br /> {<br /> return string.Format(strResout, iTatol / iMonth, "月");<br /> }<br /> else if (iTatol > iDay)<br /> {<br /> return string.Format(strResout, iTatol / iDay, "天");<br /> }<br /> else if (iTatol > iHours)<br /> {<br /> return string.Format(strResout, iTatol / iHours, "小時");<br /> }<br /> else if (iTatol > iMinutes)<br /> {<br /> return string.Format(strResout, iTatol / iMinutes, "分鐘");<br /> }<br /> else<br /> {<br /> return string.Format(strResout, iTatol, "秒");<br /> }</p><p> }

Program program = new Program();<br /> List<DateTime> dateList = new List<DateTime>();<br /> DateTime tmpDate = DateTime.Parse("2009-05-12 23:01");<br /> dateList.Add(tmpDate.AddSeconds(-11));<br /> dateList.Add(tmpDate.AddSeconds(-110));<br /> dateList.Add(tmpDate.AddSeconds(-1100));<br /> dateList.Add(tmpDate.AddSeconds(-11000));<br /> dateList.Add(tmpDate.AddSeconds(-110000));<br /> dateList.Add(tmpDate.AddSeconds(-1100000));<br /> dateList.Add(tmpDate.AddSeconds(-11000000));<br /> dateList.Add(tmpDate.AddSeconds(-110000000));<br /> foreach (DateTime beginTime in dateList)<br /> {<br /> string strDiff = program.GetDiffTime(beginTime, DateTime.Now);<br /> Console.WriteLine(strDiff);<br /> }<br /> Console.ReadLine();
