Příklady

Následující příklad vytvoří několik TimeSpan objektů pomocí 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 );

   // 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 );

Poznámky

Parametr value se převede na milisekundy, které se převedou na škrty a tento počet ticků se použije k inicializaci nového TimeSpanparametru . value Proto bude považováno za přesné pouze do nejbližší milisekundy. Všimněte si, že kvůli ztrátě přesnosti datového Double typu může tento převod vygenerovat OverflowException hodnotu pro hodnoty, které jsou blízko, ale stále jsou v rozsahu buď MinValue nebo MaxValue. To například způsobí v následujícím pokusu OverflowException o vytvoření instance objektu TimeSpan .

// 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)
