I am trying to find out a solution to the two following problems:
* given the number of the week, how do I get the days composing that week in the format for instance "dd/MM"?
* given a date (for instance 21/07/2004) how do I find the number of the week that day is belonging to?

Thanks

This might help...

you should use System.DateTime structer.
you can do like below
if numberOfWeek is 2 that means we are in the second week of year
---------------
//C#
//Part 1
DateTime dtm=new DateTime(2004,1,1);
DateTime firstDayOfWeek=dtm.AddDays((numberOfWeek-1)*7);
DateTime lastDayOfWeek=dtm.AddDays(numberOfWeek*7-1);
//then with properties and method of DateTime structure get evrything you need
//and also change the output format
//Part 2
DateTime dtm=new DateTime(2004,7,21);
double result=(double)dtm.DayOfYear/7;
if(result-System.Convert.ToInt32(result)==0)
{ return (int)result;
}
else{
 return System.Convert.ToInt32(result)+1;
}
-----------------

Hope this could help you.
