// 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, " " );

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)
