MessageBinding Class

Describes how abstract content is mapped into a concrete format.

Namespace:  System.Web.Services.Description
Assembly:  System.Web.Services (in System.Web.Services.dll)

public abstract class MessageBinding : NamedItem

The MessageBinding type exposes the following members.

Protected methodMessageBindingInitializes a new instance of the MessageBinding class.

Public propertyDocumentationGets or sets the text documentation for the instance of the DocumentableItem. (Inherited from DocumentableItem.)
Public propertyDocumentationElementGets or sets the documentation element for the DocumentableItem. (Inherited from DocumentableItem.)
Public propertyExtensibleAttributesGets or sets an array of type XmlAttribute that represents attribute extensions of WSDL to comply with Web Services Interoperability (WS-I) Basic Profile 1.1. (Inherited from DocumentableItem.)
Public propertyExtensionsGets the ServiceDescriptionFormatExtensionCollection associated with this DocumentableItem. (Inherited from DocumentableItem.)
Public propertyNameGets or sets the name of the item. (Inherited from NamedItem.)
Public propertyNamespacesGets or sets the dictionary of namespace prefixes and namespaces used to preserve namespace prefixes and namespaces when a ServiceDescription object is constructed. (Inherited from DocumentableItem.)
Public propertyOperationBindingGets the OperationBinding of which the current MessageBinding is a member.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

This abstract class forms the base class for the following classes:

The following example demonstrates a typical use of the MessageBinding class.

using System;
using System.Web.Services.Description;
class MyClass
   public static void Main()
   OperationBinding addOperationBinding = 

   public static MessageBinding CreateInputOutputBinding(string myBindName,
      bool isInputBinding)

     // Value isInputBinding = true ---> return type = InputBinding.  
     // Value isInputBinding = false --> return type = OutputBinding.
     MessageBinding myMessageBinding = null;
         case true:
            myMessageBinding = new InputBinding();
            Console.WriteLine("Added an InputBinding");
         case false:
            myMessageBinding = new OutputBinding();
            Console.WriteLine("Added an OutputBinding");
      myMessageBinding.Name = myBindName;
      SoapBodyBinding mySoapBodyBinding = new SoapBodyBinding();
      mySoapBodyBinding.Use = SoapBindingUse.Literal;
      Console.WriteLine("Added extensibility element of type : " + 
      return myMessageBinding;

   // Used to create OperationBinding instances within Binding.
   public static OperationBinding CreateOperationBinding(
      string myOperation,string targetNamespace)
      // Create OperationBinding for Operation.
      OperationBinding myOperationBinding = new OperationBinding();
      myOperationBinding.Name = myOperation;

      // Create InputBinding for operation.
      InputBinding myInputBinding = 

      // Create OutputBinding for operation.
      OutputBinding myOutputBinding = 

      // Add InputBinding and OutputBinding to OperationBinding. 
      myOperationBinding.Input = myInputBinding;
      myOperationBinding.Output = myOutputBinding;

      // Create an extensibility element for SoapOperationBinding.
      SoapOperationBinding mySoapOperationBinding = new SoapOperationBinding();
      mySoapOperationBinding.Style = SoapBindingStyle.Document;
      mySoapOperationBinding.SoapAction = targetNamespace + myOperation;

      // Add the extensibility element SoapOperationBinding to OperationBinding.
      return myOperationBinding;
