Örnekler

Aşağıdaki örnek, yöntemini kullanarak FromMilliseconds birkaç TimeSpan nesne oluşturur.

// 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()

Açıklamalar

value parametresi onay işaretine dönüştürülür ve bu sayıda değer işareti yenisini TimeSpanbaşlatmak için kullanılır. Bu nedenle, value yalnızca en yakın milisaniyeye doğru olarak kabul edilir. Veri türünün duyarlığı kaybedildiğinden, bu dönüştürmenin Double veya aralığındaki MinValueMaxValuedeğerine yakın ancak yine de değerleri için bir OverflowException oluşturabileceğini unutmayın. Örneğin, bu, aşağıdaki bir nesne örneği oluşturma girişiminde bir TimeSpan neden olurOverflowException.

// 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)
