如何计算使用日期时间选择器之间的天数 [英] how to count days between using datetime picker

问题描述

private void dateTimePicker2_ValueChanged(object sender, EventArgs e)
{  
   DateTime start = dateTimePicker1.Value.Date;
   DateTime end = dateTimePicker2.Value.Date;
   txttotal_days.Text=Convert.ToInt32(end.Subtract(start).Days).ToString();
}

我使用上面的编码来查找使用datetimepicker的日期，[当我尝试在按钮内部正常工作时]

I used above coding to find no of days using datetimepicker,[when I try inside button its working fine]

推荐答案

您可以使用TimeSpan类.

You could use a TimeSpan class.

System.DateTime dt1 =  dateTimePicker1.Value;
System.DateTime dt2 =  dateTimePicker2.Value;
System.TimeSpan diffResult = dt1.Subtract(dt2);

尝试一下:

Try this:

DateTime FirstDate = dateTimePicker1.Value;
DateTime SecondDate = dateTimePicker2.Value;
// Difference in days, hours, and minutes.
TimeSpan ts = SecondDate - FirstDate;
// Difference in days.
int differenceInDays = ts.Days;
Console.WriteLine("Difference in days: {0} ", differenceInDays);

Hi,

DateTime dt1 = dateTimePicker1.Value;
DateTime dt2 = dateTimePicker2.Value;
TimeSpan tsDiff = dt2.Subtract(dt1); //Note: Always subtract smaller date
//value from greater date
 Console.WriteLine(tsDiff.Days.ToString());
