As you see in code below The answer of code in last line must be:
Persian calendar: 5/30/1383 8:30:15 PM
But It is:
Persian calendar: 11/11/2625 8:30:15 PM
How can I avoid this BUG?
// Start Of Code
System.Globalization.PersianCalendar jc = new
System.Globalization.PersianCalendar();
DateTime thisDate = new DateTime(2004, 8, 20);
Console.WriteLine("GetMonth: month = {0}", jc.GetMonth(thisDate));
Console.WriteLine("GetDayOfMonth: month = {0}", jc.GetDayOfMonth(thisDate));
Console.WriteLine("GetYear: year = {0}", jc.GetYear(thisDate));
DateTime dt1 = new DateTime(thisDate.Year, thisDate.Month, thisDate.Day, 20,
30, 15, 500);
DateTime dt2 = jc.ToDateTime(thisDate.Year, thisDate.Month, thisDate.Day,
20, 30, 15, 500, System.Globalization.PersianCalendar.PersianEra);
Console.WriteLine("Gregorian calendar: {0}\n" + "Persian calendar: {1}",
dt1, dt2);
// End Of Code
There is inconsistency in the code: 1 - When you fill the datetime in the following line, you are actually passing Gregorian date instead of Persian dates: [quoted text, click to view] > DateTime dt2 = jc.ToDateTime(thisDate.Year, thisDate.Month,
> thisDate.Day, 20, 30, 15, 500,

You should pass the Persian dates and not Gregorian date, for example your code should look like this: DateTime dt2 = jc.ToDateTime(jc.GetYear(thisDate), jc.GetMonth(thisDate), jc.GetDayOfMonth(thisDate), 20, 30, 15, 500, System.Globalization.PersianCalendar.PersianEra); All dates, irrespective of the calendar, are stored in the same manner. So if you want to display non-Gregorian date, then you need to specify it. You are simply printing the DateTime and this default to Gregorian. The PersianCalendar is not a full calendar in .NET framework 2.0. So you can't parse dates using it. [quoted text, click to view] "kourosh" wrote:

Dear Dlasheen, I try with syntax that you write, but the result is false, jc.ToDateTime convert persian calendar to Gregorian Calendar for example it convert: 1385/03/11 -> 2006/06/01. How can I show persian calendar using: dt2? [quoted text, click to view] "DLasheen" wrote:

You have to explicitly use dt2 in the persian calendar. For example use the code below to display the date using the format "dd/mm/yy". textBox1.Text = jc.GetDayOfMonth(dt2) + "/" + jc.GetMonth(dt2) + "/" + jc.GetYear(dt2); This should give you the expected output [quoted text, click to view] "kourosh" wrote:
