Contoh

Contoh berikut membuat beberapa objek TimeSpan dengan menggunakan metode FromMilliseconds.

// Example of the TimeSpan::FromMilliseconds( double ) method.
using namespace System;
void GenTimeSpanFromMillisec( Double millisec )
{
   
   // Create a TimeSpan object and TimeSpan string from 
   // a number of milliseconds.
   TimeSpan interval = TimeSpan::FromMilliseconds( millisec );
   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}", millisec, timeInterval );
}

int main()
{
   Console::WriteLine( "This example of TimeSpan::FromMilliseconds( double )\n"
   "generates the following output.\n" );
   Console::WriteLine( "{0,21}{1,18}", "FromMilliseconds", "TimeSpan" );
   Console::WriteLine( "{0,21}{1,18}", "----------------", "--------" );

Keterangan

Parameter value dikonversi menjadi tanda centang, dan jumlah kutu tersebut digunakan untuk menginisialisasi TimeSpanbaru. Oleh karena itu, value hanya akan dianggap akurat hingga milidetik terdekat. Perhatikan bahwa, karena hilangnya presisi jenis data Double, konversi ini dapat menghasilkan OverflowException untuk nilai yang mendekati tetapi masih dalam rentang MinValue atau MaxValue. Misalnya, ini menyebabkan OverflowException dalam upaya berikut untuk membuat instans objek TimeSpan.

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds);

// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromMilliseconds TimeSpan.MaxValue.TotalMilliseconds

' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds)
