1:第一种方式:

            string firstDate = "20140226120201";
            string secondDate = "20140225115401";
            DateTime firstDateTemp = DateTime.ParseExact(firstDate, "yyyyMMddHHmmss", new System.Globalization.CultureInfo("zh-CN", true));
            DateTime secondDateTemp = DateTime.ParseExact(secondDate, "yyyyMMddHHmmss", new System.Globalization.CultureInfo("zh-CN", true));            
            TimeSpan span = firstDateTemp.Subtract(secondDateTemp);
            然后,如果相差一天,那么span.Days=1,如果是一年,那么span.Days=365
span.Hours, span.Minutes就不举例了

 

2:第二种方式:

       DateTime t1 = DateTime.Parse("2007-1-1 05:32:22");
           DateTime t2 = DateTime.Parse("2007-1-1 05:31:22");
           TimeSpan span = t1.Subtract(t2);
