问题描述

我如何获得C#中一个没有周五和周六的天数?

How do I get in C# the number of days in a month without Friday and Saturday?

推荐答案

在这里，又快又脏:

class Program
{
    static void Main(string[] args)
    {
        int month = DateTime.Today.Month;
        int year = DateTime.Today.Year;

        int daysInMonthMinusFridayAndSaturday = 0;

        for (int i = 1; i <= DateTime.DaysInMonth(year,month); i++)
        {
            DateTime thisDay = new DateTime(year,month,i);
            if(thisDay.DayOfWeek != DayOfWeek.Friday && thisDay.DayOfWeek != DayOfWeek.Saturday)
            {
                daysInMonthMinusFridayAndSaturday += 1;
            }
        }

        Console.WriteLine(daysInMonthMinusFridayAndSaturday);
        Console.ReadLine();
    }
}
