c# - 如何从一年中的某一天获取日期

Question

如何在 C# 中从 day of year 获取 date？

我有这段代码:

int a = 53;   // This is the day of year value, that I got previously
string b = Convert.ToDateTime(a).ToString();   // Trying to get the date

我需要获取值 22.2.2014。但这不起作用，我该怎么办？提前致谢。

Answer 1

int dayOfYear = 53;
int year = DateTime.Now.Year; //Or any year you want
DateTime theDate = new DateTime(year, 1, 1).AddDays(dayOfYear - 1);
string b = theDate.ToString("d.M.yyyy");   // The date in requested format
