EndpointDispatcher Class


Represents the run-time object that exposes properties that enable the insertion of run-time extensions or modifications for messages in service applications.

public ref class EndpointDispatcher
public ref class EndpointDispatcher sealed
public class EndpointDispatcher
public sealed class EndpointDispatcher
type EndpointDispatcher = class
Public Class EndpointDispatcher
Public NotInheritable Class EndpointDispatcher


The following code example shows the use of EndpointDispatcher to locate the System.ServiceModel.Dispatcher.DispatchRuntime for the endpoint and inserts a custom message inspector using an endpoint behavior.

// IEndpointBehavior Members
public void AddBindingParameters(ServiceEndpoint serviceEndpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)

public void ApplyClientBehavior(ServiceEndpoint serviceEndpoint, ClientRuntime behavior)
  behavior.MessageInspectors.Add(new EndpointBehaviorMessageInspector());

public void ApplyDispatchBehavior(ServiceEndpoint serviceEndpoint, EndpointDispatcher endpointDispatcher)
  endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new EndpointBehaviorMessageInspector());

public void Validate(ServiceEndpoint serviceEndpoint)


The EndpointDispatcher and the System.ServiceModel.Dispatcher.DispatchRuntime classes expose the runtime customization points for endpoints in a service. The EndpointDispatcher can be used to control which messages it can process and some endpoint-related information. The DispatchRuntime has a large number of properties used to insert custom extensions into the endpoint-wide runtime.

The EndpointDispatcher object is responsible for processing messages from a System.ServiceModel.Dispatcher.ChannelDispatcher when the destination address of a message matches the AddressFilter property and the message action matches the ContractFilter property. If two EndpointDispatcher objects can accept a message, the FilterPriority property value determines the higher priority endpoint.

Use the EndpointDispatcher object to configure or extend the process of receiving messages from the associated ChannelDispatcher, converting from message objects to objects used as parameters, and invoking an endpoint operation as well as the reverse process.

Typically, the EndpointDispatcher for an endpoint is obtained by implementing the IEndpointBehavior interface, but you can access the EndpointDispatcher from the other behavior interfaces.

You can use the following EndpointDispatcher properties:


EndpointDispatcher(EndpointAddress, String, String)

Initializes a new instance of the EndpointDispatcher class with the specified address, contract name, and contract namespace.

EndpointDispatcher(EndpointAddress, String, String, Boolean)

Initializes a new instance of the EndpointDispatcher class with the specified address, contract name, contract namespace, and whether the endpoint is a public, system endpoint.



Gets or sets a MessageFilter object that is used to identify whether a particular message is destined for the endpoint address.


Gets the associated ChannelDispatcher object, which can be used to inspect or modify other channel-related values and behaviors.


Gets or sets the MessageFilter object that is used to identify whether a message is destined for this contract.


Gets the endpoint contract name.


Gets the namespace of the endpoint contract.


Gets the DispatchRuntime object used to inspect, modify, or extend run-time behavior across a service endpoint or a client callback endpoint.


Gets the address of the endpoint.


Gets or sets the priority of the ContractFilter and the AddressFilter combination when the ChannelDispatcher is selecting endpoints.


Gets a value that indicates whether the endpoint is created internally by the server and not by the user.



Determines whether the specified object is equal to the current object.
