TextMessageEncodingBindingElement Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
The binding element that specifies the character encoding and message versioning used for text-based SOAP messages.
System.ServiceModel.Channels.BindingElement
System.ServiceModel.Channels.MessageEncodingBindingElement
System.ServiceModel.Channels.TextMessageEncodingBindingElement
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The TextMessageEncodingBindingElement type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | TextMessageEncodingBindingElement() | Initializes a new instance of the TextMessageEncodingBindingElement class. |
![]() | TextMessageEncodingBindingElement(MessageVersion, Encoding) | Initializes a new instance of the TextMessageEncodingBindingElement class with a specified message version and encoding. |
| Name | Description | |
|---|---|---|
![]() | MessageVersion | Gets or sets the SOAP and WS-Addressing versions that are used to format the text message. (Overrides MessageEncodingBindingElement.MessageVersion.) |
![]() | WriteEncoding | Gets or sets the encoding that is used to format the characters in the text message. |
| Name | Description | |
|---|---|---|
![]() | 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).) |
![]() | 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.) |
![]() | Clone | Creates a new TextMessageEncodingBindingElement object initialized from the current one. (Overrides BindingElement.Clone().) |
![]() | CreateMessageEncoderFactory | Creates a factory for text message encoders that employs the message version and character encoding specified by the current encoding binding element. (Overrides MessageEncodingBindingElement.CreateMessageEncoderFactory().) |
![]() | 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.) |
![]() | GetProperty<T> | Returns a typed object requested, if present, from the appropriate layer in the binding element stack. (Overrides MessageEncodingBindingElement.GetProperty<T>(BindingContext).) |
![]() | 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.) |
Encoding is the process of transforming a message into a sequence of bytes. Decoding is the reverse process. Windows Phone uses Text encoding for SOAP messages.
The text encoding represented by the TextMessageEncodingBindingElement is the most interoperable, but the least efficient encoder for XML messages. Web service or Web service client can generally understand textual XML. However, transmitting large blocks of binary data as text is not efficient.

how to implement a custom message encoder, use the MessageEncodingBindingElement class.
// This is an example of how to create a custom binding with a text encoding and HTTP tansport,
// and how to create and open a channel for the service endpoint configured with the custom binding.
public partial class MainPage : PhoneApplicationPage
{
//Declare a separate UI thread.
SynchronizationContext uiThread;
public MainPage()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
//Create a custom binding that uses HTTP and binary message encoding.
var elements = new List<BindingElement>();
elements.Add(new TextMessageEncodingBindingElement());
elements.Add(new HttpTransportBindingElement());
var binding = new CustomBinding(elements);
//Create a channel factory for the service endpoint configured with the custom binding.
var cf = new ChannelFactory<IService1>(binding, new EndpointAddress("http://localhost:10483/Service1.svc"));
//Save the synchronized context for the UI thread.
uiThread = SynchronizationContext.Current;
//Open the channel.
IService1 channel = cf.CreateChannel();
//Invoke the GetPerson method on the service asynchronously. The signature is:
//IAsyncResult BeginGetPerson(int personId, AsyncCallback callback, object state)
channel.BeginGetPerson(4, GetPersonCallback, channel);
}
//Implement the callback.
void GetPersonCallback(IAsyncResult asyncResult)
{
Person p = ((IService1)asyncResult.AsyncState).EndGetPerson(asyncResult);
//Update the UI thread and its output with the result of the method call.
uiThread.Post(UpdateUI, p);
}
//Update the result displayed for the GetPerson invocation.
private void UpdateUI(object state)
{
Person p = (Person)state;
resultPersonName.Text = "The name of the Person is: " + p.Name;
resultPersonAge.Text = "The age of the Person is: " + p.Age;
}
