C#时间比较问题

Question

我想判断当前时是否是06：00：00应该怎么做啊？

Answer 1

12小时制 DateTime.Now.ToString("hh:mm:ss")=="06:00:00"
24小时制 DateTime.Now.ToString("HH:mm:ss")=="06:00:00"

Answer 2

  If DateTime.Now.Hour = 6 Then  End If

Answer 3

 if (DateTime.Now.ToString("HH:mm:ss") == "06:00:00")
            {            }

Answer 4

bool result = DateTime.Now.ToString("HH:mm:ss").Equals("06:00:00");

Answer 5

可以对时、分、秒进行一一比较
也可以DateTime.Now.ToString().Substring ( DateTime.Now.ToString().IndexOf (' ')+1)获取当前时间进行比较

Answer 6

DateTime get_time = Convert.ToDateTime(DateTime.Now.ToString());
                    DateTime sta_ontime = Convert.ToDateTime(Convert.ToDateTime(tmp.Trim().ToString()));
                    long dat = DateAndTime.DateDiff("s", get_time, sta_ontime, FirstDayOfWeek.Sunday, FirstWeekOfYear.FirstFourDays);
                    if (dat == 0)
                    {
}

Answer 7

return DateTime.Now.ToLongTimeString() == "06:00:00";

Answer 8

        string   st1="06:00:00";           DateTime   dt1=Convert.ToDateTime(st1);   
        DateTime   dt2=    

Answer 9

        string   st1="06:00:00";   
        string   str2 =DateTime.Now().ToString("HH：mm：ss");
        DateTime   dt1=Convert.ToDateTime(st1);   
        DateTime   dt2=  Convert.ToDateTime(str2 );  
       if (DateTime.Compare(dt1,dt2) == 0)
       {
         retrun true;
       }

Answer 10

楼主，还有更傻缺的方法(DateTime.Now.Hour * 60 * 60 + DateTime.Now.Minute * 60 + DateTime.Now.Second)/(6*60*60)

Answer 11

long time1=DateTime.Now.Hour * 60 * 60 + DateTime.Now.Minute * 60 + DateTime.Now.Second;
long time2=6*60*60;bool result=(time1==time2);比字符串比较快
