MessageEncoderFactory Class

Microsoft Silverlight will reach end of support after October 2021. Learn more.

An abstract base class that represents the factory for producing message encoders that can read messages from a stream and write them to a stream for various types of message encoding.

Public MustInherit Class MessageEncoderFactory

public abstract class MessageEncoderFactory

The MessageEncoderFactory type exposes the following members.

Constructors

	Name	Description
	MessageEncoderFactory	Initializes a new instance of the MessageEncoderFactory class.

Properties

	Name	Description
	Encoder	When overridden in a derived class, gets the message encoder that is produced by the factory.
	MessageVersion	When overridden in a derived class, gets the message version that is used by the encoders produced by the factory to encode messages.

Methods

	Name	Description
	CreateSessionEncoder	Returns a message encoder that can be used to correlate messages in session-based exchanges.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Encoding is the process of transforming a message into a sequence of bytes. Decoding is the reverse process.

Use this class if you want to implement a custom message encoder. To implement your own custom message encoder, you must provide custom implementations of the following three abstract base classes:

Override the Encoder to return an instance of your custom MessageEncoder. Then wire up your custom MessageEncoderFactory to the binding element stack used to configure the service or client by overriding the CreateMessageEncoderFactory method to return an instance of this factory.

custom encoders, see Custom Encoders.

Examples

The following code shows how to write a class that is derived from MessageEncoderFactory.
