Constructors

  Name Description
Public methodSupported by Silverlight for Windows Phone BinaryMessageEncodingBindingElement Initializes a new instance of the BinaryMessageEncodingBindingElement class.

Properties

  Name Description
Public propertySupported by Silverlight for Windows Phone MessageVersion Gets or sets the SOAP message and WS-Addressing versions that are used or expected. (Overrides MessageEncodingBindingElement.MessageVersion.)

Methods

  Name Description
Public methodSupported by Silverlight for Windows Phone BuildChannelFactory<TChannel> Builds the channel factory stack on the client that creates a specified type of channel for a specified context. (Overrides BindingElement.BuildChannelFactory<TChannel>(BindingContext).)
Public methodSupported by Silverlight for Windows Phone CanBuildChannelFactory<TChannel> Returns a value that indicates whether the binding element can build a channel factory for a specific type of channel. (Inherited from BindingElement.)
Public methodSupported by Silverlight for Windows Phone Clone Creates a new BinaryMessageEncodingBindingElement object initialized from the current one. (Overrides BindingElement.Clone().)
Public methodSupported by Silverlight for Windows Phone CreateMessageEncoderFactory Creates a factory for binary message encoders that employ the SOAP and WS-Addressing versions and the character encoding specified by the current encoding binding element. (Overrides MessageEncodingBindingElement.CreateMessageEncoderFactory().)
Public methodSupported by Silverlight for Windows Phone Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone 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.)
Public methodSupported by Silverlight for Windows Phone GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone GetProperty<T> Returns the typed object requested, if present, from the appropriate layer in the channel stack. (Inherited from MessageEncodingBindingElement.)
Public methodSupported by Silverlight for Windows Phone GetType Gets the Type of the current instance. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone 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. Silverlight 5 includes two types of encoding for SOAP messages: Text and Binary.

The BinaryMessageEncodingBindingElement is the binding element that specified the .NET Binary Format for XML should be used for encoding messages, and has options to specify the character encoding and the SOAP and WS-Addressing version to be used. Binary encoding is the most efficient but least interoperable of the encoding options.

For more information about

the binding element that specifies messages are encoded using a textual representation of XML, see TextMessageEncodingBindingElement.

To implement a custom message encoder, use the MessageEncodingBindingElement class.

Examples
