TimeSpan.FromTicks(Int64) Metodo

Definizione

Restituisce un oggetto TimeSpan che rappresenta un'ora specificata, in cui la specifica è espressa in unità di tick.

public:
 static TimeSpan FromTicks(long value);
public static TimeSpan FromTicks (long value);
static member FromTicks : int64 -> TimeSpan
Public Shared Function FromTicks (value As Long) As TimeSpan

Parametri

value
Int64

Numero di tick che rappresentano un periodo di tempo.

Restituisce

Oggetto che rappresenta l'oggetto value.

Esempio

Nell'esempio seguente vengono creati diversi TimeSpan oggetti usando il FromTicks metodo .

// Example of the TimeSpan::FromTicks( __int64 ) method.
using namespace System;
void GenTimeSpanFromTicks( __int64 ticks )
{
   
   // Create a TimeSpan object and TimeSpan string from 
   // a number of ticks.
   TimeSpan interval = TimeSpan::FromTicks( ticks );
   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}", ticks, timeInterval );
}

int main()
{
   Console::WriteLine( "This example of TimeSpan::FromTicks( __int64 )\n"
   "generates the following output.\n" );
   Console::WriteLine( "{0,21}{1,18}", "FromTicks", "TimeSpan" );

   GenTimeSpanFromTicks( 864000000000 );

Si tratta di un metodo pratico con lo stesso comportamento del TimeSpan.TimeSpan(Int64) costruttore. Un singolo segno di graduazione rappresenta un centinaio di nanosecondi o un milione di secondo. Ci sono 10.000 tick in millisecondi.
