DivideByZeroException DivideByZeroException DivideByZeroException DivideByZeroException Class

定義

嘗試將整數或 Decimal 值除以零時,所擲回的例外狀況。The exception that is thrown when there is an attempt to divide an integral or Decimal value by zero.

public ref class DivideByZeroException : ArithmeticException
[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public class DivideByZeroException : ArithmeticException
type DivideByZeroException = class

範例

下列範例會在整數DivideByZeroException除法中處理例外狀況。The following example handles a DivideByZeroException exception in integer division.

using System;

public class Example
{
   public static void Main()
   {
      int number1 = 3000;
      int number2 = 0;
      try {
         Console.WriteLine(number1 / number2);
      }
      catch (DivideByZeroException) {
         Console.WriteLine("Division of {0} by zero.", number1);
      }
   }
}
// The example displays the following output:
//        Division of 3000 by zero.
Module Example
   Public Sub Main()
      Dim number1 As Integer = 3000
      Dim number2 As Integer = 0
      Try
         Console.WriteLine(number1\number2)
      Catch e As DivideByZeroException
         Console.WriteLine("Division of {0} by zero.", number1)
      End Try
   End Sub
End Module
' The example displays the following output:
'       Division of 3000 by zero.

備註

嘗試將整數或Decimal數位零DivideByZeroException除會擲回例外狀況。Trying to divide an integer or Decimal number by zero throws a DivideByZeroException exception. 若要避免例外狀況, 請確定具有整數或Decimal值的除法運算中的分母為非零。To prevent the exception, ensure that the denominator in a division operation with integer or Decimal values is non-zero.

將浮點值除以零不會擲回例外狀況;它會根據 IEEE 754 算術的規則, 產生正無限大、負無限大或不是數位 (NaN)。Dividing a floating-point value by zero doesn't throw an exception; it results in positive infinity, negative infinity, or not a number (NaN), according to the rules of IEEE 754 arithmetic. 由於下列範例會使用浮點除法而不是整數除法, 因此作業不會擲DivideByZeroException回例外狀況。Because the following example uses floating-point division rather than integer division, the operation does not throw a DivideByZeroException exception.

using System;

public class Example
{
   public static void Main()
   {
      int number1 = 3000;
      int number2 = 0;

      Console.WriteLine((double)number1 / number2);
   }
}
// The example displays the following output:
//        Infinity
Module Example
   Public Sub Main()
      Dim number1 As Integer = 3000
      Dim number2 As Integer = 0

      Console.WriteLine(number1/number2)
   End Sub
End Module
' The example displays the following output:
'       Infinity
