A message header contains optional metadata that describe a message encapsulated by the Message class.

A Message can have zero or more headers that are used as an extension mechanism to pass information in messages that are application-specific. You can use Headers to add message headers to a message by calling the Add method.

Windows Communication Foundation (WCF) provides a number of predefined message headers:

Header Name

Description

To

Contains the role that the message is targeting.

Action

Provides a description of how the message should be processed.

FaultTo

Contains the address of the node to which faults should be sent.

From

Contains the address of the node that sent the message.

Request

Indicates whether the message is a request.

MessageID

Contains the unique ID of the message.

RelatesTo

Contains the IDs of messages that are related to this message.

ReplyTo

Contains the address of the node to which a reply should be sent for a request.

The following code example demonstrates a basic client using the channel factory to send a message and read the action header from the reply.

No code example is currently available or this language may not be supported.
