abstract Headers : MessageHeaders with get

Property Value

Type: System.ServiceModel.Channels.MessageHeaders
A MessageHeaders object that represents the headers of the message.


The message has been disposed of.

A Message can have zero or more headers that are used as an extension mechanism to pass information in messages that is 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, as shown in the following table.

Provides a description of how the message should be processed.


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

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

Notes to Inheritors

When overridden in a derived class, this method returns a MessageHeaders object for the headers of the message.

The following code example shows a client that uses the channel factory to send a message and read the reply.
