DateTimeOffset.EqualsExact(DateTimeOffset) Metodo

Definizione

Determina se l'oggetto DateTimeOffset corrente rappresenta la stessa ora e ha lo stesso offset di un oggetto DateTimeOffset specificato.

public:
 bool EqualsExact(DateTimeOffset other);
public bool EqualsExact (DateTimeOffset other);
member this.EqualsExact : DateTimeOffset -> bool
Public Function EqualsExact (other As DateTimeOffset) As Boolean

Parametri

other
DateTimeOffset

Oggetto da confrontare con l'oggetto DateTimeOffset corrente.

Restituisce

Boolean

true se l'oggetto DateTimeOffset corrente e il parametro other presentano lo stesso valore di data e ora e lo stesso valore Offset; in caso contrario, false.

Esempio

Nell'esempio seguente viene illustrato l'uso del EqualsExact metodo per confrontare oggetti simili DateTimeOffset .

DateTimeOffset instanceTime = new DateTimeOffset(2007, 10, 31, 0, 0, 0,
                              DateTimeOffset.Now.Offset);

DateTimeOffset otherTime = instanceTime;
Console.WriteLine("{0} = {1}: {2}",
                  instanceTime, otherTime,
                  instanceTime.EqualsExact(otherTime));

otherTime = new DateTimeOffset(instanceTime.DateTime,
            TimeSpan.FromHours(instanceTime.Offset.Hours + 1));
Console.WriteLine("{0} = {1}: {2}",
                  instanceTime, otherTime,
                  instanceTime.EqualsExact(otherTime));

otherTime = new DateTimeOffset(instanceTime.DateTime + TimeSpan.FromHours(1),
                TimeSpan.FromHours(instanceTime.Offset.Hours + 1));
Console.WriteLine("{0} = {1}: {2}",
                  instanceTime, otherTime,
                  instanceTime.EqualsExact(otherTime));
// The example produces the following output:
//       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 12:00:00 AM -07:00: True
//       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 12:00:00 AM -06:00: False
//       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 1:00:00 AM -06:00: False
let instanceTime = DateTimeOffset(2007, 10, 31, 0, 0, 0, DateTimeOffset.Now.Offset)

let otherTime = instanceTime
printfn $"{instanceTime} = {otherTime}: {instanceTime.EqualsExact otherTime}"

let otherTime = DateTimeOffset(instanceTime.DateTime, TimeSpan.FromHours(instanceTime.Offset.Hours + 1 |> float))
printfn $"{instanceTime} = {otherTime}: {instanceTime.EqualsExact otherTime}"

let otherTime = DateTimeOffset(instanceTime.DateTime + TimeSpan.FromHours 1, TimeSpan.FromHours(instanceTime.Offset.Hours + 1 |> float))
printfn $"{instanceTime} = {otherTime}: {instanceTime.EqualsExact otherTime}"

// The example produces the following output:
//       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 12:00:00 AM -07:00: True
//       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 12:00:00 AM -06:00: False
//       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 1:00:00 AM -06:00: False

Commenti

Poiché più fusi orari condividono un singolo offset, un valore restituito di true non garantisce che l'oggetto other e corrente rappresentino gli orari nello stesso fuso orario.

A differenza del EqualsExact metodo , gli overload del Equals metodo determinano solo se due DateTimeOffset valori rappresentano un singolo punto nel tempo. Non indicano che due valori hanno la stessa data e ora e lo stesso offset.
