OperationBinding Class

Provides specifications for protocols and data formats for the messages used in the action supported by the XML Web service. This class cannot be inherited.

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

[XmlFormatExtensionPointAttribute(L"Extensions")]

  NameDescription
Public propertyBindingGets the Binding of which the current OperationBinding is a member.
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 collection of extensibility elements specific to the current OperationBinding. (Overrides DocumentableItem::Extensions.)
Public propertyFaultsGets the FaultBindingCollection associated with the OperationBinding instance.
Public propertyInputGets or sets the InputBinding associated with the OperationBinding.
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 propertyOutputGets or sets the OutputBinding associated with the OperationBinding.

  NameDescription
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.)

The OperationBinding class corresponds to the Web Services Description Language (WSDL) <operation> element enclosed by the <binding> element, which in turn corresponds to the Binding class. For more information about WSDL, see the specification at http://www.w3.org/TR/wsdl/.

The following example demonstrates the use of the properties and methods exposed by the OperationBinding class. It takes an existing ServiceDescription and adds support for the SOAP protocol.
