Esempi

Nell'esempio seguente viene utilizzata MinValue la proprietà per impedire OverflowException a un oggetto durante Int16 la conversione in un valore.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

Commenti

Il valore di questa costante è-32768; ovvero 0x8000 esadecimale.The value of this constant is -32768; that is, hexadecimal 0x8000.

La MinValue proprietà viene in genere utilizzata per impedire OverflowException un oggetto quando si esegue la conversione da un tipo numerico con un intervallo più Int32 basso Int64, ad esempio un Int16oggetto o, a un oggetto.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. Questo utilizzo è illustrato nell'esempio.The example illustrates this usage.
