# AddressFilterModeAddressFilterModeAddressFilterModeAddressFilterMode Enum

## Definition

Specifies the type of match semantics used by the dispatcher to route incoming messages to the correct endpoint.

public enum class AddressFilterMode
public enum AddressFilterMode
type AddressFilterMode =
Public Enum AddressFilterMode
Inheritance
AddressFilterModeAddressFilterModeAddressFilterModeAddressFilterMode

## Fields

 Any Any Any Any 2 Indicates a filter that matches on any address of an incoming message. Exact Exact Exact Exact 0 Indicates a filter that does an exact match on the address of an incoming message. Prefix Prefix Prefix Prefix 1 Indicates a filter does the longest prefix matches on the address of an incoming message.

## Examples

[ServiceBehavior(AddressFilterMode = AddressFilterMode.Prefix)]
public class CalculatorService : ICalculator
{
public double Add(double n1, double n2)
{
return n1 + n2;
}

public double Subtract(double n1, double n2)
{
return n1 - n2;
}

public double Multiply(double n1, double n2)
{
return n1 * n2;
}

public double Divide(double n1, double n2)
{
return n1 / n2;
}
}

<ServiceBehavior(AddressFilterMode := AddressFilterMode.Prefix)> _
Public Class CalculatorService
Implements ICalculator
Public Function Add(ByVal n1 As Double, ByVal n2 As Double) As Double Implements ICalculator.Add
Return n1 + n2
End Function

Public Function Subtract(ByVal n1 As Double, ByVal n2 As Double) As Double Implements ICalculator.Subtract
Return n1 - n2
End Function

Public Function Multiply(ByVal n1 As Double, ByVal n2 As Double) As Double Implements ICalculator.Multiply
Return n1 * n2
End Function

Public Function Divide(ByVal n1 As Double, ByVal n2 As Double) As Double Implements ICalculator.Divide
Return n1 / n2
End Function
End Class

## Remarks

The value of the AddressFilterMode enumeration is set on the AddressFilterMode property.

The longest prefix match criterion specified by Prefix requires that the destination address be matched by the largest number of leading address bits in the filter. The default value is Exact.
