Hi,
I'm trying to piece together a simple calendar in C#. It is not a
winform app, but a console application (so I can't just use the winform
DatePicker).
I've come across a couple of C examples, with
http://www.codingunit.com/how-to-make-a-calendar-in-c being the simplest
to port over. Problem is that Feb started on a Wednesday and this comes
up with a Monday for some odd reason.
Does anyone know a quick and simple way to do this in C#?
My code currently looks like this
public class calendar
{
private List<int> daysInMonth;
public calendar()
{
daysInMonth = new List<int>();
daysInMonth.AddRange(new int[] { 0, 31, 28, 31, 30, 31, 30,
31, 31, 30, 31, 30, 31 });
}
private int determineDayCode(int year)
{
Console.WriteLine("year = {0}", year);
int d1 = (year - 1)/ 4;
int d2 = (year - 1)/ 100;
int d3 = (year - 1)/ 400;
return Convert.ToInt32((year + d1 - d2 + d3) % 7);
}
private void checkForLeapYear(int year)
{
if (year % 4 == 0 && year % 100 != 0 || year % 400 == 0)
daysInMonth[2] = 29;
else
daysInMonth[2] = 28;
}
private List<int> createCal(int ddc, int month, int year)
{
int day;
List<int> cal = new List<int>();
Console.WriteLine("1 + ddc * 5 = {0}", 1 + ddc * 5);
for (day = 1; day <= 1 + ddc * 5; ++day)
cal.Add(0);
for (day = 1; day <= daysInMonth[month]; ++day)
cal.Add(day);
return cal;
}
public List<int> generateCalendar(int month, int year)
{
List<int> cal = new List<int>();
int ddc = determineDayCode(year);
checkForLeapYear(year);
cal = createCal(ddc, month, year);
return cal;
}
}
The calling methods passes in month and year and expects back a list.
The idea is that it will put a 0 if the start of the week is not on that
day (so for Feb, it should read 0,0,0,1 but it's coming out 0,1)
Thanks
Paul
