Beispiele

Im folgenden Beispiel wird die MinValue-Eigenschaft verwendet, um eine OverflowException zu verhindern, wenn Sie in einen Int16-Wert umwandelt.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.", _
                        newNumber)
   Else
      Console.WriteLine("Unable to convert {0} to an Int16.", number)
   End If                     
Next
' The example displays the following output to the console:
'       Unable to convert 162345 to an Int16.

Hinweise

Der Wert dieser Konstante ist-32768; Das heißt, hexadezimal 0X8000.The value of this constant is -32768; that is, hexadecimal 0x8000.

Die MinValue-Eigenschaft wird in der Regel verwendet, um eine OverflowException zu verhindern, wenn Sie einen numerischen Typ mit einem größeren unteren Bereich (z. b. einem Int32 oder einem Int64) in einen Int16umwandelt.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. Diese Verwendung wird in diesem Beispiel veranschaulicht.The example illustrates this usage.
