C# 获取给定开始日期和结束日期之间的每月工作日

我需要编写一个方法，在其中传递开始日期和结束日期。输出应该是一个带有两个参数的列表。一个是月名，另一个是该月的工作日数。移除卫星和太阳

请告知

public List<MonthDaysData> GetMonthwiseWorkingdays(DateTime? start, DateTime? end)
{
List<MonthDaysData> monthdays = new List<MonthDaysData>();

// Coding to get the output
return monthdays;
}

public class MonthDaysData 
{ 
  public Int32? Month { get; set; } 
  public Int32? days { get; set; } 
}

这听起来像是家庭作业，你没有展示你已经尝试过的东西，所以我不会为你编写所有的代码。在这件事上有许多不同的看法。有关返回工作日日期列表的简单实现，请参见示例：

IEnumerable<DateTime> workingDays = WorkDaysBetween(DateTime start, DateTime end);

从这里，您必须能够选择正确的投影。

您可以使用扩展方法获得如下值

public static class Extensions
{
    public static List<MonthDaysData> GetWorkingDaysPerMonthTo(this DateTime from, 
                         DateTime to)
    {
        var workings = new Dictionary<int, int>();
        var currentDateTime = from;

        while (currentDateTime <= to)
        {
            if (currentDateTime.DayOfWeek != DayOfWeek.Saturday 
                                  && currentDateTime.DayOfWeek != DayOfWeek.Sunday 
                                  && !currentDateTime.IsHoliday("CountryCode"))
                if (!workings.ContainsKey(currentDateTime.Month))
                    workings.Add(currentDateTime.Month, 1);
                else
                {
                    int curWork;
                    workings.TryGetValue(currentDateTime.Month, out curWork);
                    curWork++;
                    workings.Remove(currentDateTime.Month);
                    workings.Add(currentDateTime.Month, curWork);
                }

            currentDateTime = currentDateTime.AddDays(1);
        }
        return workings.Select(work => new MonthDaysData {Month = work.Key, 
                                                       days = work.Value}).ToList();
    } 

    public static bool IsHoliday(this DateTime date, string countryCode)
    {
        // some service that takes a country code and 
        // returns true/false if its a holiday
        return false;
    }
}

不过，这只是将工作日作为工作日，您需要检查公共假日等。

所以为什么不从开始日期循环到结束日期，检查是否为假日，如果必要，将其添加到列表中？到目前为止，您尝试了什么？也提供MonthDaysData定义。公共类MonthDaysData{public Int32？Month{get；set；}public Int32？days{get；set；}}嗨，andy，谢谢您的回复。。我可以得到两个日期之间的总天数。但我需要的是每月一次的工作日分割。你试过什么？搜索两个日期之间的C Get工作日会产生很多结果。如果日期跨度超过一年，该怎么办？

public static class Extensions
{
    public static List<MonthDaysData> GetWorkingDaysPerMonthTo(this DateTime from, 
                         DateTime to)
    {
        var workings = new Dictionary<int, int>();
        var currentDateTime = from;

        while (currentDateTime <= to)
        {
            if (currentDateTime.DayOfWeek != DayOfWeek.Saturday 
                                  && currentDateTime.DayOfWeek != DayOfWeek.Sunday 
                                  && !currentDateTime.IsHoliday("CountryCode"))
                if (!workings.ContainsKey(currentDateTime.Month))
                    workings.Add(currentDateTime.Month, 1);
                else
                {
                    int curWork;
                    workings.TryGetValue(currentDateTime.Month, out curWork);
                    curWork++;
                    workings.Remove(currentDateTime.Month);
                    workings.Add(currentDateTime.Month, curWork);
                }

            currentDateTime = currentDateTime.AddDays(1);
        }
        return workings.Select(work => new MonthDaysData {Month = work.Key, 
                                                       days = work.Value}).ToList();
    } 

    public static bool IsHoliday(this DateTime date, string countryCode)
    {
        // some service that takes a country code and 
        // returns true/false if its a holiday
        return false;
    }
}

var today = new DateTime(2014, 10, 16);
var dates = today.GetWorkingDaysPerMonthTo(new DateTime(2014, 12, 16));
