ClientOperation Class

ClientOperation Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Used to modify or extend the execution behavior of a specific contract operation in a client object or client channel object. This class cannot be inherited.


Namespace:  System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public sealed class ClientOperation

The ClientOperation type exposes the following members.

Public methodClientOperation(ClientRuntime, String, String)Initializes a new instance of the ClientOperation class using the specified ClientRuntime, name, and action values.
Public methodClientOperation(ClientRuntime, String, String, String)Initializes a new instance of the ClientOperation class using the specified ClientRuntime, name, action, and reply action values.

Public propertyActionGets the action of the operation.
Public propertyBeginMethodGets or sets the method associated with an asynchronous operation.
Public propertyDeserializeReplyGets or sets a value that indicates whether the Formatter property value is used to deserialize the reply message.
Public propertyEndMethodGets or sets the method that implements the asynchronous end method for the operation.
Public propertyFormatterGets or sets the formatter that serializes objects into messages and deserializes messages into objects.
Public propertyIsInitiatingGets or sets a value that indicates whether a session can be started by a message to this operation.
Public propertyIsOneWayGets or sets a value that indicates whether the operation is a one-way operation.
Public propertyIsTerminatingGets or sets a value that indicates whether this operation is the last one in a session.
Public propertyNameGets the name of the operation.
Public propertyParentGets the containing ClientRuntime object.
Public propertyReplyActionGets the action of the reply message for this operation.
Public propertySerializeRequestGets or sets a value that specifies whether the Formatter object serializes an outbound message.
Public propertySyncMethodGets or sets the method that is associated with this operation.

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 the Object 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 ClientOperation class is the location for client runtime modifications and insertion point for custom extensions that are scoped to a single service operation. (To modify client run-time behavior for all messages in a contract, use the ClientRuntime class.)

The following properties enable you to insert custom objects or modify the client execution behavior:

  • Use the Formatter property to insert a custom IClientMessageFormatter implementation for an operation or modify the current formatter.

  • Use the SerializeRequest property to control who serializes an outbound message.

  • Use the DeserializeReply property to control who deserializes an inbound message.

  • Use the Action property to access the WS-Addressing action of the request message and the ReplyAction property to access the response message action.

  • Use the BeginMethod and EndMethod to specify which client methods are associated with an asynchronous operation.

  • Use the IsInitiating and IsTerminating properties to control whether a session is initiated or is torn down, respectively, when the operation is called.

  • Use the IsOneWay property to control whether the client waits for a response before completing the invocation.

  • Use the Parent property to obtain the containing ClientRuntime object.

  • Use the Name property to get the name of the operation.

  • Use the SyncMethod property to control which method is mapped to the operation.
