除了星期日之外，如何计算两个日期之间的天数？ [英] How to calculate a no of days between two dates except sunday?

问题描述

你好先生，



我计算了两天之间的天数，如下所示：

 DateTime startdate =  new  DateTime（）; 
 
 startdate = Convert.ToDateTime（DateMontYearToYearMonthDate（stdate.Text））; 
 
 DateTime Enddate =  new  DateTime（）; 
 
 Enddate = Convert.ToDateTime（DateMontYearToYearMonthDate（endate.Text））; 
 
 TimeSpan点头=（Enddate  -  startdate）; 
 
 numdays.Text = nod.TotalDays.ToString（）; 

但是我需要计算没有两个日期之间的天数除了星期日？



如何在c＃中执行此操作。如果你回答它会对我这样做更有帮助。提前谢谢。

解决方案

DateTime startdate = Convert.ToDateTime（01/13/2013​​）;

DateTime enddate = Convert.ToDateTime（01/18 / 2013）;

int count = 0;

while（startdate！= enddate）

{

if （startdate.DayOfWeek.CompareTo（DayOfWeek.Sunday）！= 0）

{

count ++;

startdate = startdate.AddDays（1） ;

}

其他

{

startdate = startdate.AddDays（1）;

}

}

MessageBox.Show（no of days+ count）;

这里有一个解决方案：http://stackoverflow.com/questions/1617049/calculate-the-number-of-business-days-between-two-日期 [ ^ ]需要进行一些小改动才能包含星期六 - 它假设工作周为5天，你有6天。



但请你，你不需要这样转换！

 startdate = Convert.ToDateTime（DateMontYearToYearMonthDate（stdate.Text））; 
 

不要玩文字：看看使用DateTime.TryParseExact [ ^ ] - 它允许您准确指定输入字符串的外观，并在单个操作中转换它（如果用户输入了错误的日期，则报告错误）

Hello Sir,

I have calculated no of days between two days like that given below:

DateTime startdate = new DateTime();

         startdate =Convert.ToDateTime(DateMontYearToYearMonthDate(stdate.Text));

         DateTime Enddate = new DateTime();

        Enddate = Convert.ToDateTime(DateMontYearToYearMonthDate(endate.Text));

          TimeSpan nod = (Enddate - startdate);

            numdays.Text = nod.TotalDays.ToString();

but i need to calculate no of days between two dates except sunday?

how to do this in c#.if u answer it will more help for me to do this.thanks in advance.

解决方案

DateTime startdate = Convert.ToDateTime("01/13/2013");
DateTime enddate = Convert.ToDateTime("01/18/2013");
int count = 0;
while (startdate != enddate)
{
if (startdate.DayOfWeek.CompareTo(DayOfWeek.Sunday) != 0)
{
count++;
startdate = startdate.AddDays(1);
}
else
{
startdate = startdate.AddDays(1);
}
}
MessageBox.Show("no of days"+count);

There is a solution here: http://stackoverflow.com/questions/1617049/calculate-the-number-of-business-days-between-two-dates[^] which will need a small change to include Saturdays - it assumes a 5 day working week, where you have a six day.

But please, you don''t need to convert like that!

startdate =Convert.ToDateTime(DateMontYearToYearMonthDate(stdate.Text));

Don''t play with text: look at using DateTime.TryParseExact[^] instead - it lets you specify exactly what the input string should look like, and convert it in a single operation (or report an error if the user entered a bad date).
