Represents the context information for a service instance.

public sealed class InstanceContext : System.ServiceModel.Channels.CommunicationObject, System.ServiceModel.IExtensibleObject<System.ServiceModel.InstanceContext>

type InstanceContext = class
    inherit CommunicationObject
    interface IExtensibleObject<InstanceContext>

Public NotInheritable Class InstanceContext
Inherits CommunicationObject
Implements IExtensibleObject(Of InstanceContext)

Inheritance: Object

Implements: IExtensibleObject<InstanceContext>

Examples

The following code illustrates how to obtain instance context information from a service:

string info = "";

OperationContext operationContext = OperationContext.Current;
InstanceContext instanceContext = operationContext.InstanceContext;

info += "    " + "State: " + instanceContext.State.ToString() + "\n";
info += "    " + "ManualFlowControlLimit: " + instanceContext.ManualFlowControlLimit.ToString() + "\n";
info += "    " + "HashCode: " + instanceContext.GetHashCode().ToString() + "\n";

return info;

Constructors

InstanceContext(Object)	Initializes a new instance of the InstanceContext class for a specified object that implements the service instance.
InstanceContext(ServiceHostBase, Object)	Initializes a new instance of the InstanceContext class for a specified object that implements the service instance and is hosted by a specified host.
InstanceContext(ServiceHostBase)	Initializes a new instance of the InstanceContext class for a service hosted by a specified host.

Properties

DefaultCloseTimeout	When overridden in a derived class, gets the default interval of time provided for a close operation to complete. (Inherited from CommunicationObject)
DefaultOpenTimeout	When overridden in a derived class, gets the default interval of time provided for an open operation to complete. (Inherited from CommunicationObject)
Extensions	Gets the extension collection, if any, associated with the service instance.
Host	Gets the host for the service instance.
IncomingChannels	Gets the sessionful channels that are incoming to the service instance.
IsDisposed	Gets a value that indicates whether the communication object has been disposed. (Inherited from CommunicationObject)
ManualFlowControlLimit	Gets or sets a limit on the number of messages that can be processed by the instance context.
OutgoingChannels	Gets the sessionful channels that are outgoing from the service instance.
State	Gets a value that indicates the current state of the communication object. (Inherited from CommunicationObject)
SynchronizationContext	Gets or sets the context used for thread synchronization with the current instance context.
ThisLock	Gets the mutually exclusive lock that protects the class instance during a state transition. (Inherited from CommunicationObject)

Methods

Abort()	Causes a communication object to transition immediately from its current state into the closing state. (Inherited from CommunicationObject)
BeginClose(AsyncCallback, Object)	Begins an asynchronous operation to close a communication object. (Inherited from CommunicationObject)
BeginClose(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to close a communication object with a specified timeout. (Inherited from CommunicationObject)
BeginOpen(AsyncCallback, Object)	Begins an asynchronous operation to open a communication object. (Inherited from CommunicationObject)
BeginOpen(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from CommunicationObject)
Close()	Causes a communication object to transition from its current state into the closed state. (Inherited from CommunicationObject)
Close(TimeSpan)	Causes a communication object to transition from its current state into the closed state within a specified interval of time. (Inherited from CommunicationObject)
EndClose(IAsyncResult)	Completes an asynchronous operation to close a communication object. (Inherited from CommunicationObject)
EndOpen(IAsyncResult)	Completes an asynchronous operation to open a communication object. (Inherited from CommunicationObject)
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Fault()	Causes a communication object to transition from its current state into the faulted state. (Inherited from CommunicationObject)
GetCommunicationObjectType()	Gets the type of communication object. (Inherited from CommunicationObject)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetServiceInstance()	Returns the instance of the service for the instance context.
GetServiceInstance(Message)	Returns the instance of the service for the instance context in response to an incoming message.
GetType()	Gets the Type of the current instance. (Inherited from Object)
IncrementManualFlowControlLimit(Int32)	Increases the number of messages that can be processed by the service instance.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnAbort()	Inserts processing on a communication object after it transitions to the closing state due to the invocation of a synchronous abort operation. (Inherited from CommunicationObject)
OnBeginClose(TimeSpan, AsyncCallback, Object)	Inserts processing after a communication object transitions to the closing state due to the invocation of an asynchronous close operation. (Inherited from CommunicationObject)
OnBeginOpen(TimeSpan, AsyncCallback, Object)	Inserts processing on a communication object after it transitions to the opening state due to the invocation of an asynchronous open operation. (Inherited from CommunicationObject)
OnClose(TimeSpan)	Inserts processing on a communication object after it transitions to the closing state due to the invocation of a synchronous close operation. (Inherited from CommunicationObject)
OnClosed()	Invoked during the transition of a communication object into the closing state. (Inherited from CommunicationObject)
OnClosing()	Invoked during the transition of a communication object into the closing state. (Inherited from CommunicationObject)
OnEndClose(IAsyncResult)	Completes an asynchronous operation on the close of a communication object. (Inherited from CommunicationObject)
OnEndOpen(IAsyncResult)	Completes an asynchronous operation on the open of a communication object. (Inherited from CommunicationObject)
OnFaulted()	Inserts processing on a communication object after it transitions to the faulted state due to the invocation of a synchronous fault operation. (Inherited from CommunicationObject)
OnOpen(TimeSpan)	Inserts processing on a communication object after it transitions into the opening state which must complete within a specified interval of time. (Inherited from CommunicationObject)
OnOpened()	Invoked during the transition of a communication object into the opened state. (Inherited from CommunicationObject)
OnOpening()	Invoked during the transition of a communication object into the opening state. (Inherited from CommunicationObject)
