public abstract class SoapExtensionImporter

The SoapExtensionImporter type exposes the following members.

Protected methodSoapExtensionImporterInitializes a new instance of the SoapExtensionImporter class.

Public propertyImportContextGets or sets the SoapProtocolImporter instance that invokes the ImportMethod method.

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.)
Public methodImportMethodWhen overridden in a derived class, adds code attribute declarations to any method that represents an operation in a binding.
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 SoapExtensionImporter abstract class exposes an abstract method, ImportMethod, which allows a derived class to add metadata to any method that represents an operation in a binding. The method itself is not an input method. The code attributes, which are added to all Web methods in a binding class, represent extensions to the SOAP Web services protocol, for example, for adding extra headers to an outgoing SOAP message or doing extra processing on an incoming SOAP message.

You can use a class derived from SoapExtensionImporterto extend the generation of client proxy code or abstract server code. You can use such a derived class in conjunction with a class derived from the abstract SoapExtension class, which extends run-time processing of SOAP messages on the client or service.

You can specify SoapExtensionImporter in a configuration file through the soapExtensionImporterTypes configuration element and its child add element. You can apply the configuration to:

  • An ASP.NET Web application: service or client.

  • A stand-alone .NET Framework application: client only.
