Exemples

L’exemple suivant utilise la MinValue propriété pour empêcher un OverflowException lors de la conversion en une Int16 valeur.The following example uses the MinValue property to prevent an OverflowException when converting to an Int16 value.

array<Int64>^ numbersToConvert = {162345, 32183, -54000};
Int16 newNumber;
for each (Int64 number in numbersToConvert)
{
   if (number >= Int16::MinValue && number <= Int16::MaxValue)
   {
      newNumber = Convert::ToInt16(number);
      Console::WriteLine("Successfully converted {0} to an Int16.", 
                         newNumber);
   }
   else
   {
      Console::WriteLine("Unable to convert {0} to an Int16.", number);
   }
}
// The example displays the following output:
//       Unable to convert 162345 to an Int16.
//       Successfully converted 32183 to an Int16.
//       Unable to convert -54000 to an Int16.   
long[] numbersToConvert = {162345, 32183, -54000};
short newNumber;
foreach (long number in numbersToConvert)
{
   if (number >= Int16.MinValue && number <= Int16.MaxValue)
   {
      newNumber = Convert.ToInt16(number);
      Console.WriteLine("Successfully converted {0} to an Int16.",
                        newNumber);
   }
   else
   {
      Console.WriteLine("Unable to convert {0} to an Int16.", number);
   }
}
// The example displays the following output to the console:
//       Unable to convert 162345 to an Int16.
//       Successfully converted 32183 to an Int16.
//       Unable to convert -54000 to an Int16.
Dim numbersToConvert() As Long = {162345, 32183, -54000}
Dim newNumber As Int16
For Each number As Long In NumbersToConvert
   If number >= Int16.MinValue And number <= Int16.MaxValue Then
      newNumber = Convert.ToInt16(number)
      Console.WriteLine("Successfully converted {0} to an Int16.", _

   Else
      Console.WriteLine("Unable to convert {0} to an Int16.", number)
   End If                     
Next
' The example displays the following output to the console:

Remarques

La valeur de cette constante est-32768 ; c’est-à-dire, hexadécimal 0x8000.The value of this constant is -32768; that is, hexadecimal 0x8000.

La MinValue propriété est généralement utilisée pour empêcher un OverflowException lors de la conversion d’un type numérique avec une plage plus faible (par exemple, Int32 ou Int64 ) en Int16 .The MinValue property is typically used to prevent an OverflowException when converting from a numeric type with a greater lower range (such as an Int32 or an Int64) to an Int16. L’exemple illustre cette utilisation.The example illustrates this usage.
