Public Class DivideByZeroException
	Inherits ArithmeticException

NameDescription
System_CAPS_pubmethodDivideByZeroException()

Initializes a new instance of the DivideByZeroException class.

System_CAPS_protmethodDivideByZeroException(SerializationInfo, StreamingContext)

Initializes a new instance of the DivideByZeroException class with serialized data.

System_CAPS_pubmethodDivideByZeroException(String)

Initializes a new instance of the DivideByZeroException class with a specified error message.

System_CAPS_pubmethodDivideByZeroException(String, Exception)

Initializes a new instance of the DivideByZeroException class with a specified error message and a reference to the inner exception that is the cause of this exception.

NameDescription
System_CAPS_pubpropertyData

Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)

System_CAPS_pubpropertyHelpLink

Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)

System_CAPS_pubpropertyHResult

Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)

System_CAPS_pubpropertyInnerException

Gets the Exception instance that caused the current exception.(Inherited from Exception.)

System_CAPS_pubpropertyMessage

Gets a message that describes the current exception.(Inherited from Exception.)

System_CAPS_pubpropertySource

Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)

System_CAPS_pubpropertyStackTrace

Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)

System_CAPS_pubpropertyTargetSite

Gets the method that throws the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetBaseException()

When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetObjectData(SerializationInfo, StreamingContext)

When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)

System_CAPS_pubmethodGetType()

Gets the runtime type of the current instance.(Inherited from Exception.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_proteventSerializeObjectState

Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

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.

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

For more information, see Single and Double.

The following Microsoft intermediate language (MSIL) instructions throw DivideByZeroException:

  • div

  • div.un

  • rem

  • rem.un

DivideByZeroException uses the HRESULT COR_E_DIVIDEBYZERO, which has the value 0x80020012.

For a list of initial property values for an instance of DivideByZeroException, see the DivideByZeroException constructors.

The following example handles a DivideByZeroException exception in integer division.

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.
