 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

TimeSpan

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" );
   Console::WriteLine( "{0,21}{1,18}", "---------", "--------" );
   GenTimeSpanFromTicks( 1 );
   GenTimeSpanFromTicks( 12345 );
   GenTimeSpanFromTicks( 123456789 );
   GenTimeSpanFromTicks( 1234567898765 );
   GenTimeSpanFromTicks( 12345678987654321 );
   GenTimeSpanFromTicks( 10000000 );
   GenTimeSpanFromTicks( 600000000 );
   GenTimeSpanFromTicks( 36000000000 );
   GenTimeSpanFromTicks( 864000000000 );
   GenTimeSpanFromTicks( 18012202000000 );

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.
