I'm trying to create a method that receives a week number and year and returns a date.
Let's say that I pick week number 31 and the year 2003; I expect to receive the day of that Sunday in dd-mon-yyyy format.

I know how to get the week number for a given date but I don't know if there is a built-in method for converting it to a date within the VB.NET or c# framework

Thx

I'm not sure if there is one. I ran into something similar and I typed in the dates manually so to speak. I knew what month I was going to be working in - so if week 50 was picked it would have to be in December likewise, if week 3 was picked it would be january. I used a Select Case statement in Classic ASP to achieve it.

Hi,

I do this by using the following method:



Dim myDATE as date
Dim myYear, myWeek as integer

myDATE = date.parse("1.1." & myYear.ToString)
myDATE = myDATE.date.AddDays(7 * (myWeek-1) - myDATE.DayOfWeek)

Greetings

I don't know if anyone is still looking to handle this but here is what I have found works, it assumes you want the first day of the
week to be monday (it's for a work schedule).

Code modified for easier display in forum.

DateTime theDay;
DateTime startOfWeek
Double span = Convert.ToDouble(theDay.DayOfWeek)-1)

if(theDay.DayOfWeek != DayOfWeek.Monday){
     startOfWeek = theDay.Subtract(TimeSpan.FromDays(span);
}else{
     startOfWeek = theDay;
}

"Where ever you go, there you are."

Dim iWeek as Integer
Dim strYear as String

iWeek = 30
strYear = "2004"

Msgbox DateAdd("ww", iWeek, "1/1/" & strYear)
