Przykłady

Poniższy przykład tworzy kilka TimeSpan obiektów przy użyciu FromMinutes metody .

// 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 );
}

Uwagi

Parametr value jest konwertowany na milisekundy, który jest konwertowany na znaczniki, a ta liczba znaczników służy do inicjowania nowego TimeSpanelementu . value W związku z tym będzie uważana za dokładną tylko dla najbliższej milisekundy. Należy pamiętać, że ze względu na utratę dokładności Double typu danych ta konwersja może wygenerować OverflowException wartość dla wartości zbliżonych do , ale nadal w zakresie MinValue wartości lub MaxValue. Na przykład powoduje OverflowException to wykonanie następującej próby utworzenia TimeSpan wystąpienia obiektu.

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