Feldwert

Beispiele

Im folgenden Beispiel wird die MaxValue Eigenschaft, um zu verhindern, dass ein OverflowException beim Konvertieren in ein Int32 Wert.The following example uses the MaxValue property to prevent an OverflowException when converting to an Int32 value.

using namespace System;

void main()
{
   array<Int64>^ numbersToConvert = gcnew array<Int64> { 162345, 32183, -54000, 
                                                         Int64::MaxValue/2 };
   Int32 newNumber;
   for each (Int64 number in numbersToConvert)
   {
      if ((number >= Int32::MinValue) && (number <= Int32::MaxValue))
      {
         newNumber = Convert::ToInt32(number);
         Console::WriteLine("Successfully converted {0} to an Int32.",
