Este constructor interpreta year, month y day como un año, mes y día en el calendario gregoriano. Para crear una instancia de un DateTime valor mediante el año, mes y día en otro calendario, llame al DateTime(Int32, Int32, Int32, Int32, Int32, Int32, Int32, Int32, Calendar, DateTimeKind) constructor .

En el ejemplo siguiente se llama al DateTime(Int32, Int32, Int32, Int32, Int32, Int32, Int32, Calendar, DateTimeKind) constructor dos veces para crear una instancia de dos DateTime valores. La primera llamada crea una instancia de un DateTime valor mediante un PersianCalendar objeto . Dado que el calendario persa no se puede designar como calendario predeterminado para una referencia cultural, mostrar una fecha en el calendario persa requiere llamadas individuales a sus PersianCalendar.GetMonthmétodos , PersianCalendar.GetDayOfMonthy PersianCalendar.GetYear . La segunda llamada al constructor crea una instancia de un DateTime valor mediante un HijriCalendar objeto . En el ejemplo se cambia la referencia cultural actual a Árabe (Siria) y se cambia el calendario predeterminado de la referencia cultural actual al calendario Hijri. Dado que Hijri es el calendario predeterminado de la referencia cultural actual, el Console.WriteLine método lo usa para dar formato a la fecha. Cuando se restaura la referencia cultural actual anterior (que es inglés (Estados Unidos) en este caso, el Console.WriteLine método usa el calendario gregoriano predeterminado de la referencia cultural actual para dar formato a la fecha.

En el caso de las aplicaciones en las que la portabilidad de los datos de fecha y hora o un grado limitado de reconocimiento de zona horaria es importante, puede usar el constructor correspondiente DateTimeOffset .

El System.Globalization espacio de nombres proporciona varios calendarios, incluidos GregorianCalendar y JulianCalendar.

En el ejemplo se cambia la referencia cultural actual a Árabe (Siria) y se cambia el calendario predeterminado de la referencia cultural actual al calendario Hijri. Dado que Hijri es el calendario predeterminado de la referencia cultural actual, el Console.WriteLine método lo usa para dar formato a la fecha. Cuando se restaura la referencia cultural actual anterior (que es inglés (Estados Unidos) en este caso, el Console.WriteLine método usa el calendario gregoriano predeterminado de la referencia cultural actual para dar formato a la fecha.

La propiedad Kind se inicializa en Unspecified.

Los valores permitidos para year, monthy day dependen de calendar. Se produce una excepción si la fecha y hora especificadas no se pueden expresar mediante calendar.

En el caso de las aplicaciones en las que es importante la portabilidad de los datos de fecha y hora o un grado limitado de reconocimiento de zona horaria, puede usar el constructor correspondiente DateTimeOffset .

El System.Globalization espacio de nombres proporciona varios calendarios, incluidos GregorianCalendar y JulianCalendar.

En el ejemplo siguiente se llama al DateTime(Int32, Int32, Int32, Calendar) constructor dos veces para crear una instancia de dos DateTime valores. La primera llamada crea una instancia de un DateTime valor mediante un PersianCalendar objeto . Dado que el calendario persa no se puede designar como calendario predeterminado para una referencia cultural, mostrar una fecha en el calendario persa requiere llamadas individuales a sus PersianCalendar.GetMonthmétodos , PersianCalendar.GetDayOfMonthy PersianCalendar.GetYear . La segunda llamada al constructor crea una instancia de un DateTime valor mediante un HijriCalendar objeto . En el ejemplo se cambia la referencia cultural actual a Árabe (Siria) y se cambia el calendario predeterminado de la referencia cultural actual al calendario Hijri. Dado que Hijri es el calendario predeterminado de la referencia cultural actual, el Console.WriteLine método lo usa para dar formato a la fecha. Cuando se restaura la referencia cultural actual anterior (que es inglés (Estados Unidos) en este caso, el Console.WriteLine método usa el calendario gregoriano predeterminado de la referencia cultural actual para dar formato a la fecha.

La hora del día para el resultado DateTime es medianoche (00:00:00). La propiedad Kind se inicializa en Unspecified.

Los valores permitidos para year, monthy day dependen de calendar. Se produce una excepción si la fecha y hora especificadas no se pueden expresar mediante calendar.

El System.Globalization espacio de nombres proporciona varios calendarios, incluidos GregorianCalendar y JulianCalendar.

En el ejemplo siguiente se usa el DateTime(Int32, Int32, Int32) constructor para crear una instancia de un DateTime valor. En el ejemplo también se muestra que esta sobrecarga crea un DateTime valor cuyo componente de hora es igual a medianoche (o 0:00).

DateTime date1 = new DateTime(2010, 8, 18);
Console.WriteLine(date1.ToString());
// The example displays the following output:
//      8/18/2010 12:00:00 AM

let date1 = DateTime(2010, 8, 18)

Este constructor interpreta year, monthy day como un año, mes y día en el calendario gregoriano. Para crear una instancia de un DateTime valor mediante el año, mes y día en otro calendario, llame al DateTime(Int32, Int32, Int32, Calendar) constructor .

La hora del día para el resultado DateTime es medianoche (00:00:00). La propiedad Kind se inicializa en DateTimeKind.Unspecified.

Ejemplos

En el DateTime(Int32, Int32, Int32, Int32, Int32, Int32, Calendar) ejemplo siguiente se llama al constructor dos veces para crear una instancia de dos DateTime valores. La primera llamada crea una instancia de un DateTime valor mediante un PersianCalendar objeto . Dado que el calendario persa no se puede designar como el calendario predeterminado para una referencia cultural, mostrar una fecha en el calendario persa requiere llamadas individuales a sus PersianCalendar.GetMonthmétodos , PersianCalendar.GetDayOfMonthy PersianCalendar.GetYear . La segunda llamada al constructor crea una instancia de un DateTime valor mediante un HijriCalendar objeto . En el ejemplo se cambia la referencia cultural actual al árabe (Siria) y se cambia el calendario predeterminado de la referencia cultural actual al calendario hijri. Dado que Hijri es el calendario predeterminado de la referencia cultural actual, el Console.WriteLine método lo usa para dar formato a la fecha. Cuando se restaura la referencia cultural actual anterior (que es inglés (Estados Unidos) en este caso, el Console.WriteLine método usa el calendario gregoriano predeterminado de la referencia cultural actual para dar formato a la fecha.
