推荐答案

在这里可以获取两个日期之间的总天数

Here You Can Get The Total Number Of Days Between The Two Dates

DateTime d1=DateTime.MinValue;
DateTime d2=DateTime.MaxValue;
TimeSpan span = d2 - d1;
Console.WriteLine
         ( "There're {0} days between {1} and {2}" , span.TotalDays, d1.ToString(), d2.ToString() );

对于叶子，您必须编写单独的例程，然后从总天数中减去.

然后，您将获得确切的天数.

For The Leaves You Have to Write A Separate Routine And Then Subtract It From Total Days.

Then You Will Get The Exact Number Of Days.

Calculating Business Hours[^]

如果日期不存在，人们总是可以迭代...相距不远.此代码段假定没有假期.

One can always iterate... if the dates aren''t too far apart. This code snippet assumes there are no holidays.

using System;

namespace Codeproject.Answers
{
    public static class BusinessDaysCounter
    {
        public static long LeaveDays(DateTime from, DateTime to)
        {
            if (to < from)
            {
                return LeaveDays(to, from);
            }

            long days = 0;
            DateTime d = from;
            while (d <= to)
            {
                if (d.DayOfWeek != DayOfWeek.Saturday && d.DayOfWeek != DayOfWeek.Sunday)
                {
                    days++;
                }
                d = d.AddDays(1);
            }

            return days;
        }

    }
}
