获取所有DateTimes之间的两个'DateTime's在C＃ [英] Getting all DateTimes between two 'DateTime's in C#

问题描述

我有两个 DateTime s，我想在这些日期之间获取所有 DateTime 。例如，如果我的日期像01.01.2010 - 05.01.2010，我的函数应该给我一个日期列表（List），它必须包含01.01.2010，02.01.2010，03.01.2010，04.01.2010和05.01.2010。

I have two DateTimes, and I want to get all DateTimes between these Dates. Such as, if my Dates are like 01.01.2010 - 05.01.2010, my function should return me a list of date (List), and it must contain 01.01.2010, 02.01.2010, 03.01.2010, 04.01.2010, and 05.01.2010.

我写了一个这样的功能。工作正常，如果我的日期在一个月。如果我的日期像01.01.2010 - 05.02.2010那样不行。因为月份改变了，我的功能无法处理。 C＃中是否有函数返回两个日期之间的所有日期？或者如何处理月份变化？

I wrote a function like this. It works fine, if my dates are in a month. It won't work if my dates are like 01.01.2010 - 05.02.2010. Because the month changed, and my function can't handle it. Is there a function in C# that returns all dates between two dates? Or how can I handle month change?

public void GetAllDatesAndInitializeTickets(DateTime startingDate, DateTime endingDate)
    {
        List<DateTime> allDates = new List<DateTime>();

        int starting = startingDate.Day;
        int ending = endingDate.Day;

        for (int i = starting; i <= ending; i++)
        {
            allDates.Add(new DateTime(startingDate.Year, startingDate.Month, i));
        }

推荐答案

您可以直接在循环中使用 DateTime 对象代替 int 。 DateTime.AddDays 正确处理月底。

You can use DateTime objects directly in the loop, in place of your int. DateTime.AddDays handles month ends correctly.

for (DateTime date = startingDate; date <= endingDate; date = date.AddDays(1))
    allDates.Add(date);
