public static bool Equals (DateTime t1, DateTime t2);

static member Equals : DateTime * DateTime -> bool

Public Shared Function Equals (t1 As DateTime, t2 As DateTime) As Boolean

Parametri

Restituisce

Boolean

true se i due valori sono uguali; in caso contrario, false.true if the two values are equal; otherwise, false.

Esempio

Nell'esempio seguente viene illustrato il Equals metodo.The following example demonstrates the Equals method.

System::DateTime today1 = System::DateTime(
   System::DateTime::Today.Ticks );
System::DateTime today2 = System::DateTime(
   System::DateTime::Today.Ticks );
System::DateTime tomorrow = System::DateTime(
   System::DateTime::Today.AddDays( 1 ).Ticks );

// todayEqualsToday gets true.
bool todayEqualsToday = System::DateTime::Equals( today1, today2 );

// todayEqualsTomorrow gets false.
bool todayEqualsTomorrow = System::DateTime::Equals( today1, tomorrow );

System.DateTime today1 =
        new System.DateTime(System.DateTime.Today.Ticks);
System.DateTime today2 =
        new System.DateTime(System.DateTime.Today.Ticks);
System.DateTime tomorrow =
        new System.DateTime(
                    System.DateTime.Today.AddDays(1).Ticks);

// todayEqualsToday gets true.
bool todayEqualsToday = System.DateTime.Equals(today1, today2);

// todayEqualsTomorrow gets false.
bool todayEqualsTomorrow = System.DateTime.Equals(today1, tomorrow);

Dim today1 As New System.DateTime(System.DateTime.Today.Ticks)
Dim today2 As New System.DateTime(System.DateTime.Today.Ticks)
Dim tomorrow As New System.DateTime( _
                        System.DateTime.Today.AddDays(1).Ticks)

' todayEqualsToday gets true.
Dim todayEqualsToday As Boolean = System.DateTime.Equals(today1, today2)

' todayEqualsTomorrow gets false.
Dim todayEqualsTomorrow As Boolean = System.DateTime.Equals(today1, tomorrow)

Commenti

t1 e t2 sono uguali se i Ticks valori delle relative proprietà sono uguali.t1 and t2 are equal if their Ticks property values are equal. I Kind valori delle proprietà non vengono considerati nel test per verificarne l'uguaglianza.Their Kind property values are not considered in the test for equality.

        DateTime one = DateTime.UtcNow;

// This code example displays the following:

L'istanza corrente e value sono uguali se i Ticks valori delle relative proprietà sono uguali.The current instance and value are equal if their Ticks property values are equal. I Kind valori delle proprietà non vengono considerati nel test per verificarne l'uguaglianza.Their Kind property values are not considered in the test for equality.

Questo metodo implementa l' System.IEquatable<T> interfaccia e offre prestazioni leggermente migliori rispetto al Equals metodo perché il value parametro non deve essere convertito in un oggetto.This method implements the System.IEquatable<T> interface, and performs slightly better than the Equals method because the value parameter does not have to be converted to an object.
