TimeSpan.LessThan(TimeSpan, TimeSpan) TimeSpan.LessThan(TimeSpan, TimeSpan) TimeSpan.LessThan(TimeSpan, TimeSpan) TimeSpan.LessThan(TimeSpan, TimeSpan) Operator

Definizione

Indica se un oggetto TimeSpan specificato è minore di un altro oggetto TimeSpan specificato.Indicates whether a specified TimeSpan is less than another specified TimeSpan.

public:
 static bool operator <(TimeSpan t1, TimeSpan t2);
public static bool operator < (TimeSpan t1, TimeSpan t2);
static member ( < ) : TimeSpan * TimeSpan -> bool
Public Shared Operator < (t1 As TimeSpan, t2 As TimeSpan) As Boolean

Parametri

t1
TimeSpan TimeSpan TimeSpan TimeSpan

Primo intervallo di tempo da confrontare.The first time interval to compare.

t2
TimeSpan TimeSpan TimeSpan TimeSpan

Secondo intervallo di tempo da confrontare.The second time interval to compare.

Restituisce

true se il valore di t1 è minore del valore di t2; in caso contrario, false.true if the value of t1 is less than the value of t2; otherwise, false.

Esempi

Nell'esempio seguente vengono confrontate alcune TimeSpan oggetti da un riferimento TimeSpan usando il LessThan operatore.The following example compares several TimeSpan objects to a reference TimeSpan using the LessThan operator.

using namespace System;

// Compare TimeSpan parameters, and display them with the results.
