// Create a TimeSpan object and TimeSpan string from
// a number of days.
TimeSpan interval = TimeSpan::FromDays( days );
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}", days, timeInterval );

Keterangan
Parameter value
dikonversi ke milidetik, yang dikonversi menjadi tick, dan jumlah tick tersebut digunakan untuk menginisialisasi yang baru TimeSpan. Oleh karena itu, value
hanya akan dianggap akurat hingga milidetik terdekat. Perhatikan bahwa, karena hilangnya presisi Double jenis data, konversi ini dapat menyebabkan OverflowException nilai yang mendekati tetapi masih dalam rentang baik MinValue atau MaxValue. Misalnya, ini menyebabkan OverflowException dalam upaya berikut untuk membuat instans TimeSpan objek.
// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromDays(TimeSpan.MaxValue.TotalDays);
// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromDays TimeSpan.MaxValue.TotalDays
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromDays(TimeSpan.MaxValue.TotalDays)
