Poniższy przykład tworzy kilka TimeSpan obiektów przy użyciu FromDays metody .

// Example of the TimeSpan.FromDays( double ) method.
using System;

        // Create a TimeSpan object and TimeSpan string from 
        // a number of days.

        string   timeInterval = interval.ToString( );

        // Pad the end of the TimeSpan string with spaces if it 
        // does not contain milliseconds.

Uwagi

Parametr value jest konwertowany na milisekundy, który jest konwertowany na znaczniki, a ta liczba znaczników jest używana do inicjowania nowego TimeSpan. value W związku z tym zostanie uznane za dokładne tylko w najbliższej milisekundie. Należy pamiętać, że ze względu na utratę dokładności Double typu danych ta konwersja może spowodować OverflowException , że dla wartości, które są bliskie, ale nadal w zakresie MinValue wartości lub MaxValue. Na przykład powoduje to, że w OverflowException poniższej próbie utworzenia TimeSpan wystąpienia obiektu.

// 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)
