Beispiele

Im folgenden Beispiel werden mehrere TimeSpan -Objekte mithilfe FromMinutes der-Methode erstellt.The following example creates several TimeSpan objects using the FromMinutes method.

// Example of the TimeSpan::FromMinutes( double ) method.
using namespace System;
void GenTimeSpanFromMinutes( double minutes )
{
   
   // Create a TimeSpan object and TimeSpan string from 
   // a number of minutes.
   TimeSpan interval = TimeSpan::FromMinutes( minutes );
   String^ timeInterval = interval.ToString();
   
   // Pad the end of the TimeSpan string with spaces if it 
   // does not contain milliseconds.
   int pIndex = timeInterval->IndexOf( ':' );
   pIndex = timeInterval->IndexOf( '.', pIndex );
   if ( pIndex < 0 )
      timeInterval = String::Concat( timeInterval, "        " );

   Console::WriteLine( "{0,21}{1,26}", minutes, timeInterval );
}

Hinweise

Der value -Parameter wird in Millisekunden konvertiert, die in Ticks konvertiert werden, und die Anzahl der Ticks wird zum Initialisieren der neuen TimeSpanverwendet.The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new TimeSpan. value Daher wird nur für die nächste Millisekunde als genau gilt.Therefore, value will only be considered accurate to the nearest millisecond. Beachten Sie, dass diese Konvertierung aufgrund des Verlusts der Double Genauigkeit des-Datentyps einen OverflowException für Werte generieren kann, die in der Nähe von liegen, aber MinValue noch MaxValueim Bereich von oder liegen.Note that, because of the loss of precision of the Double data type, this conversion can generate an OverflowException for values that are near to but still in the range of either MinValue or MaxValue. Dies bewirkt OverflowException z. b., dass im folgenden Versuch, ein TimeSpan -Objekt zu instanziieren.For example, this causes an OverflowException in the following attempt to instantiate a TimeSpan object.

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMinutes(TimeSpan.MaxValue.TotalMinutes);
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMinutes(TimeSpan.MaxValue.TotalMinutes)
