简单获取两个时间的时间差函数

 1 #region 时间差 d返回天数,h返回小时,m返回分钟,s返回秒

 2         public static int DateDiff(DateTime DateTime1, DateTime DateTime2, string strCase)

 3         {

 4             string dateDiff = null;

 5             try

 6             {

 7                 TimeSpan ts1 = new TimeSpan(DateTime1.Ticks);

 8                 TimeSpan ts2 = new TimeSpan(DateTime2.Ticks);

 9                 TimeSpan ts = ts1.Subtract(ts2).Duration();

10                 switch (strCase)

11                 {

12                     case "d": dateDiff = ts.Days.ToString();

13                         break;

14                     case "h": dateDiff = ts.Hours.ToString();

15                         break;

16                     case "m": dateDiff = ts.Minutes.ToString();

17                         break;

18                     case "s": dateDiff = ts.Seconds.ToString();

19                         break;

20                 }

21             }

22             catch

23             {

24             }

25             return Int32.Parse(dateDiff);

26         }

27         #endregion

使用方法：

DateDiff(DateTime.Now, time, "d");//差的天数
