示例
以下示例根据 Um Al Qura 日历显示 的多个组件 DateTime 的值。
using System;
using System.Globalization;
public class Example
{
public static void Main()
{
DateTime date1 = new DateTime(2011, 4, 3, new GregorianCalendar());
Calendar cal = new UmAlQuraCalendar();
Console.WriteLine("{0:MMMM d, yyyy} in the Gregorian calendar is equivalent to:", date1);
DisplayCalendarInfo(cal, date1);
// Add 2 years and 10 months by calling UmAlQuraCalendar methods.
date1 = cal.AddYears(date1, 2);
date1 = cal.AddMonths(date1, 10);
Console.WriteLine("After adding 2 years and 10 months in the {0} calendar,",
GetCalendarName(cal));
Console.WriteLine("{0:MMMM d, yyyy} in the Gregorian calendar is equivalent to:", date1);
DisplayCalendarInfo(cal, date1);
}
private static void DisplayCalendarInfo(Calendar cal, DateTime date1)
{
Console.WriteLine(" Calendar: {0}", GetCalendarName(cal));
Console.WriteLine(" Era: {0}", cal.GetEra(date1));
Console.WriteLine(" Year: {0}", cal.GetYear(date1));
Console.WriteLine(" Month: {0}", cal.GetMonth(date1));

}
private static string GetCalendarName(Calendar cal)
{
return cal.ToString().Replace("System.Globalization.", "").
Replace("Calendar", "");
}
}
