Examples

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.

Remarks

Trying to divide an integer or Decimal number by zero throws a DivideByZeroException exception. To prevent the exception, ensure that the denominator in a division operation with integer or Decimal values is non-zero.

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. 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
