asp.net中两个日期之间的天数

Question

I find the number of days between the date of the employee's employment and the date of the day, and multiply by the daily amount. The only complaint is that when I find out the number of days between two dates, it calculates over 31 days for the months that draw 31 days naturally. I need to trade over 30 days while I get the dates between two dates.

How can I do that?

Answer 1

Do you want something like this?

DateTime date1 = new DateTime(2016, 10, 3);
DateTime date2 = new DateTime(2016, 11, 3);
var numberOfDays = date2.Subtract(date1).TotalDays;

Answer 2

I Hope this is what you wanted:

 DateTime firstDay = DateTime.ParseExact("2016-10-03", "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture);
 DateTime lastDate = DateTime.ParseExact("2016-11-03", "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture);
 double daysBetween = (lastDate - firstDay).TotalDays;

Answer 3

如果您只对整月感兴趣，可以使用以下代码

var normalisedDays = ((lastDate.Year - firstDate.Year) * 12 + lastDate.Month - firstDate.Month) * 30;

Answer 4

in Controll :

DateTime Date_1 = Date_Start;
DateTime Date_2 = Date_End;
TimeSpan difference = Date_2  - Date_1 ;
var days = difference.TotalDays;

in Script :

<script>
function calculateDifference()
{
    var Date_Start= document.getElementById("Date_Start").value;
    var Date_End= document.getElementById("Date_End").value;
    var Date_StartSplit = Date_Start.split("/");
    var Date_EndSplit = Date_End.split("/");

    var StartDate = new Date(Date_StartSplit[2], Date_StartSplit[0] - 1, Date_StartSplit[1]);
    var EndDate = new Date(Date_EndSplit[2], Date_EndSplit[0] - 1, Date_EndSplit[1]);
    var res = Math.abs(StartDate - EndDate) / 1000;
    var days = Math.floor(res / 86400);
    document.getElementById("Nombre_days").value = days;

}
</script>
