System.Runtime.Remoting.Messaging Namespace

Contains classes used to create and transmit messages. The remoting infrastructure uses messages to communicate with remote objects. Messages are used to transmit remote method calls, to activate remote objects, and to communicate information. A message object carries a set of named properties, including action identifiers, envoy information, and parameters. Some of the most important classes of the System.Runtime.Remoting.Messaging namespace are the AsyncResult class, the RemotingSurrogateSelector class, and the ReturnMessage class.

Classes

AsyncResult	Encapsulates the results of an asynchronous operation on a delegate.
CallContext	Provides a set of properties that are carried with the execution code path. This class cannot be inherited.
ConstructionCall	Implements the IConstructionCallMessage interface to create a request message that constitutes a constructor call on a remote object.
ConstructionResponse	Implements the IConstructionReturnMessage interface to create a message that responds to a call to instantiate a remote object.
Header	Defines the out-of-band data for a call.
InternalMessageWrapper	Wraps remoting data for passing between message sinks, either for requests from client to server or for the subsequent responses.
LogicalCallContext	Provides a set of properties that are carried with the execution code path during remote method calls.
MethodCall	Implements the IMethodCallMessage interface to create a request message that acts as a method call on a remote object.
MethodCallMessageWrapper	Implements the IMethodCallMessage interface to create a request message that acts as a method call on a remote object.
MethodResponse	Implements the IMethodReturnMessage interface to create a message that acts as a method response on a remote object.
MethodReturnMessageWrapper	Implements the IMethodReturnMessage interface to create a message that acts as a response to a method call on a remote object.
OneWayAttribute	Marks a method as one way, without a return value and out or ref parameters.
RemotingSurrogateSelector	Selects the remoting surrogate that can be used to serialize an object that derives from a MarshalByRefObject.
ReturnMessage	Holds a message returned in response to a method call on a remote object.

Interfaces

ILogicalThreadAffinative	Marks an object that can propagate outside of an AppDomain in a LogicalCallContext.
IMessage	Contains communication data sent between cooperating message sinks.
IMessageCtrl	Provides a way to control asynchronous messages after they have dispatched using the AsyncProcessMessage(IMessage, IMessageSink).
IMessageSink	Defines the interface for a message sink.
IMethodCallMessage	Defines the method call message interface.
IMethodMessage	Defines the method message interface.
IMethodReturnMessage	Defines the method call return message interface.
IRemotingFormatter	Provides the remote procedure call (RPC) interface for all formatters.

Delegates

HeaderHandler	Represents the method that will handle processing of headers on the stream during deserialization.
MessageSurrogateFilter	Determines whether the RemotingSurrogateSelector class should ignore a particular IMessage property while creating an ObjRef for a MarshalByRefObject class.

Remarks

The AsyncResult class stores and returns the results of an asynchronous method call. AsyncResult instances contain the return value, call status, the delegate used for the call, and the other information about the asynchronous method call.

The RemotingSurrogateSelector class can be used to control serialization of objects that extend MarshalByRefObject. A RemotingSurrogateSelector selects the surrogate used in serialization and deserialization of such objects. A surrogate is an object that can control serialization or deserialization of an object.

The ReturnMessage class holds information returned after a remote method call. A ReturnMessage holds the return value and any out or ref parameters that resulted from the remote method call.
