How to get date from day of year

How can I get date from day of year in C#?

I have this code :

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

I need to get the value 22.2.2014. But this doesn't work, what should I do? Thanks in advance.

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

Use

DateTime.AddDays()

Initialize a date to start of the year , then just add a to that using this function

Assuming you want the current year?

int a = 53;
DateTime date = new DateTime(DateTime.Now.Year, 1,1).AddDays(a -1);

int a = 53;
var dt = new DateTime(DateTime.Now.Year, 1, 1).AddDays(a - 1);
string b = dt.ToString();
