遍历给定年份的所有日子[重复]

Question

我想从给定年份获取日期列表List<string>，格式如下：dd.MM.yyyy

public List<string> GetDays(int year)
{
    List<string> lst = new List<string>();

    foreach-day-in-year // TO DO iterate days from given year
    {
       string day="";

       // TO DO  iterate all days

       lst.Add(day);
    }       

    return lst;
}

Answer 1

    public IList<string> GetDays(int year)
    {
        var days = new List<string>();
        var start = new DateTime(year, 1, 1);

        while (start.Year == year)
        {
            days.Add(start.ToString("dd.MM.yyyy"));
            start = start.AddDays(1);
        }

        return days;
    }
