Asp.Net计算时间差

c#计算时间差实现方法:

DateTime DateTime1,

        DateTime2 = DateTime.Now;//现在时间  

        DateTime1 = Convert.ToDateTime("2009-04-24 20:00:00"); //设置要求的减的时间  

        TimeSpan ts1 = new TimeSpan(DateTime1.Ticks);

        TimeSpan ts2 = newTimeSpan(DateTime2.Ticks);

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

 

        //显示时间差 

        StringBuilder dateDiff = newStringBuilder();

        dateDiff.Append(ts.Days.ToString() + "天");

        dateDiff.Append(ts.Hours.ToString() + "小时");

        dateDiff.Append(ts.Minutes.ToString() + "分钟");

        dateDiff.Append(ts.Seconds.ToString() + "秒");

 

        Response.Write(dateDiff.ToString());
