The following example demonstrates the Hour property.
System::DateTime moment = System::DateTime(
1999, 1, 13, 3, 57, 32, 11 );
// Year gets 1999.
int year = moment.Year;
// Month gets 1 (January).
int month = moment.Month;
// Day gets 13.
int day = moment.Day;
// Hour gets 3.
int hour = moment.Hour;
// Minute gets 57.
int minute = moment.Minute;
// Second gets 32.
int second = moment.Second;
// Millisecond gets 11.
int millisecond = moment.Millisecond;
System.DateTime moment = new System.DateTime(
1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;
// Month gets 1 (January).
int month = moment.Month;
// Day gets 13.
int day = moment.Day;
// Hour gets 3.
int hour = moment.Hour;
// Minute gets 57.
int minute = moment.Minute;
// Second gets 32.
int second = moment.Second;
// Millisecond gets 11.
int millisecond = moment.Millisecond;
open System
let moment = System.DateTime(1999, 1, 13, 3, 57, 32, 11)
// Year gets 1999.
let year = moment.Year
// Month gets 1 (January).
let month = moment.Month
// Day gets 13.
let day = moment.Day
// Hour gets 3.
let hour = moment.Hour
// Minute gets 57.
let minute = moment.Minute
// Second gets 32.
let second = moment.Second
// Millisecond gets 11.
let millisecond = moment.Millisecond
Dim moment As New System.DateTime(1999, 1, 13, 3, 57, 32, 11)
' Year gets 1999.
Dim year As Integer = moment.Year
' Month gets 1 (January).
Dim month As Integer = moment.Month
' Day gets 13.
Dim day As Integer = moment.Day
' Hour gets 3.
Dim hour As Integer = moment.Hour
' Minute gets 57.
Dim minute As Integer = moment.Minute
' Second gets 32.
Dim second As Integer = moment.Second
' Millisecond gets 11.
Dim millisecond As Integer = moment.Millisecond
The value of the Hour property is always expressed using a 24-hour clock. To retrieve a string that represents the hour of a date and time using a 12-hour clock, call the DateTime.ToString(String) or DateTime.ToString(String, IFormatProvider) method with the "h" custom format specifier. For example:
DateTime date1 = new DateTime(2008, 4, 1, 18, 53, 0);
Console.WriteLine(date1.ToString("%h")); // Displays 6
Console.WriteLine(date1.ToString("h tt")); // Displays 6 PM
let date1 = DateTime(2008, 4, 1, 18, 53, 0)
date1.ToString "%h"
|> printfn "%s" // Displays 6
date1.ToString "h tt"
|> printfn "%s" // Displays 6 PM
Dim date1 As Date = #04/01/2008 6:53:00PM#
Console.WriteLine(date1.ToString("%h")) ' Displays 6
Console.WriteLine(date1.ToString("h tt")) ' Displays 6 PM
