c# 判斷時間是否在 某一時間段內

1.判斷時間是否在某一時間段內

protected bool getTimeSpan(string timeStr)
{ 
    //判斷當前時間是否在工作時間段內
    string _strWorkingDayAM = "08:30";//工作時間上午08:30
    string _strWorkingDayPM = "17:30";
    TimeSpan dspWorkingDayAM = DateTime.Parse(_strWorkingDayAM).TimeOfDay;
    TimeSpan dspWorkingDayPM = DateTime.Parse(_strWorkingDayPM).TimeOfDay;

    //string time1 = "2017-2-17 8:10:00";
    DateTime t1 = Convert.ToDateTime(timeStr);

    TimeSpan dspNow = t1.TimeOfDay;
    if (dspNow > dspWorkingDayAM && dspNow < dspWorkingDayPM)
    {
        return true;
    }
    return false;
}

 

測試

protected string getResult=string.Empty;
        protected void Page_Load(object sender, EventArgs e)
        {
            string time1 = "2017-2-17 9:45:00";
            //DateTime t1 = Convert.ToDateTime(time1);
            bool resultBool = getTimeSpan(time1);
            getResult = Convert.ToString(resultBool);
        }

結果：
