Contoh
Contoh berikut membuat beberapa TimeSpan objek menggunakan FromSeconds metode .
// Example of the TimeSpan::FromSeconds( double ) method.
using namespace System;
void GenTimeSpanFromSeconds( double seconds )
{
// Create a TimeSpan object and TimeSpan string from
// a number of seconds.
TimeSpan interval = TimeSpan::FromSeconds( seconds );
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}", seconds, timeInterval );
}
int main()
{
Console::WriteLine( "This example of TimeSpan::FromSeconds( double )\n"
"generates the following output.\n" );
Console::WriteLine( "{0,21}{1,18}", "FromSeconds", "TimeSpan" );
Console::WriteLine( "{0,21}{1,18}", "-----------", "--------" );

Keterangan
Parameter value dikonversi menjadi milidetik, yang dikonversi menjadi tanda centang, dan jumlah kutu tersebut digunakan untuk menginisialisasi yang baru TimeSpan. Oleh karena itu, value hanya akan dianggap akurat dengan milidetik terdekat. Perhatikan bahwa, karena hilangnya presisi Double jenis data, ini dapat menghasilkan OverflowException untuk nilai yang dekat tetapi masih dalam rentang baik MinValue atau MaxValue, Ini adalah penyebab OverflowException, misalnya, dalam upaya berikut untuk membuat TimeSpan instans objek.
// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromSeconds(TimeSpan.MaxValue.TotalSeconds);
// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromSeconds TimeSpan.MaxValue.TotalSeconds
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromSeconds(TimeSpan.MaxValue.TotalSeconds)
