The chapter covers the following topics:. How to create a DateTime. Understand DateTime properties.
How to add and subtract date and time using DateTime. Find days in a month and year. How to compare two dates, times or DateTime. How to format dates and timesCreating DateTimeThere are several ways to create a DateTime object. A DateTime object can have a Date, Time, Localization, culture, milliseconds, and kind.The code in Listing 1 uses various constructors of DateTime structure to create DateTime objects. // Add Years and Days. aDay.AddYears(2);.
aDay.AddDays(12);. // Add Hours, Minutes, Seconds, Milliseconds, and Ticks.
aDay.AddHours(4.25);. Ocarina of time 2d download. aDay.AddMinutes(15);. aDay.AddSeconds(45);.
aDay.AddMilliseconds(200);. aDay.AddTicks(5000);Listing 4The DateTime structure does not have similar Subtract methods. Only Subtract method is used to subtract the DateTime components. For example, if we need to subtract 12 days from a DateTime, we can create another DateTime object or a TimeSpan object with 12 days and subtract it from the DateTime. Vesa to din rail. Alternatively, we can use a minus operator to subtract a DateTime or TimeSpan from a DateTime.The code snippet in Listing 5 creates a DateTime object and subtracts another DateTime and a TimeSpan object. Code also shows how to subtract just days or hours or other components from a DateTime. DateTime firstDate = new DateTime(2002, 10, 22);.
DateTime secondDate = new DateTime(2009, 8, 11);. int result = DateTime.Compare(firstDate, secondDate);. if (result. DateTime firstDate = new DateTime(2002, 10, 22);. DateTime secondDate = new DateTime(2009, 8, 11);.
int compareResult = firstDate.CompareTo(secondDate);. if (compareResult. DateTime dob = new DateTime(2002, 10, 22);.
string dateFormats = dob.GetDateTimeFormats;. foreach ( string format in dateFormats). Console.WriteLine(format)Listing 10The code snippet in Listing 10 generates output as in Figure 2.Figure 2The GetDateTimeFormats method also has an overload that takes a format specifier as a parameter and converts a DateTime to that format. It is very important to understand the DateTime format specifiers to get the desired formats.

DateTime newDt = DateTime.Parse(dt);. Console.WriteLine(newDt.ToString);Listing 15 Converting DateTimeThe DateTime structure is full of self-explanatory conversion methods that convert a DateTime to a specified type.
These methods are ToBinary, ToFileTime, ToLocalTime, ToLongDateString, ToLongTimeString, ToOADate, ToShortDateString, ToShortTimeString, ToString, and ToUniversalTime.The code snippet in Listing 16 uses some of these methods to convert a DateTime to specified types.
