Exemples

L’exemple suivant génère les codes de hachage de TimeSpan plusieurs objets à GetHashCode l’aide de la méthode.The following example generates the hash codes of several TimeSpan objects using the GetHashCode method.

// Example for the TimeSpan::GetHashCode( ) method.
using namespace System;
void DisplayHashCode( TimeSpan interval )
{
   
   // Create a hash code and a string representation of 
   // the TimeSpan parameter.
   String^ timeInterval = interval.ToString();
   int hashCode = interval.GetHashCode();
   
   // 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( "{0,22}   0x{1:X8}, {1}", timeInterval, hashCode );
}

int main()
{
   Console::WriteLine( "This example of TimeSpan::GetHashCode( ) generates "
   "the following \noutput, which displays "
   "the hash codes of representative TimeSpan \n"
   "objects in hexadecimal and decimal formats.\n" );

   Console::WriteLine( "{0,22}   {1,10}", "--------        ", "---------" );

Remarques

Deux TimeSpan objets peuvent avoir le même code de hachage même s’ils représentent des valeurs d’heure différentes.Two TimeSpan objects might have the same hash code even though they represent different time values.
