问题描述

可以请您分享一下您的逻辑吗.....
当前日期在当前月份的1号到20号之间，
我有点卡住..

can you please share your logic for this.....
current date is between the 1st and 20th of the current month,
I,m kinda stuck..

推荐答案

DateTime dt = DateTime.Now; // your input date
DateTime now = DateTime.Now; // current datetime
var abc = (dt.Day > 1 && dt.Day < 20) && dt.Month ==  now.Month ? true : false;

希望对您有帮助.

尝试:

Try:

DateTime now = DateTime.Now;
DateTime dtFirst = new DateTime(now.Year, now.Month, 1);
DateTime dtTwentieth = new DateTime(now.Year, now.Month, 20);
DateTime test = new DateTime(2011, 12, 17);
if (test >= dtFirst && test <= dtTwentieth)
    {
    Console.WriteLine("Inside");
    }
else
    {
    Console.WriteLine("Outside");
    }

//dateStart,dateEnd are date time picker object
DateTime ds = dateStart.Value;
DateTime de = dateEnd.Value;
TimeSpan ts = de - ds;
int days = ts.Days;
