![]() | 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. |
| Name | Description | |
|---|---|---|
![]() | Abort() | Causes a communication object to transition immediately from its current state into the closing state.(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.) |
![]() | 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() | |
![]() | IncrementManualFlowControlLimit(Int32) | Increases the number of messages that can be processed by the service instance. |
![]() | Open() | Causes a communication object to transition from the created state into the opened state.(Inherited from CommunicationObject.) |
![]() | Open(TimeSpan) | Causes a communication object to transition from the created state into the opened state within a specified interval of time.(Inherited from CommunicationObject.) |
![]() | ReleaseServiceInstance() | Releases the service instance. |
![]() | ThrowIfDisposed() | Throws an exception if the communication object is disposed.(Inherited from CommunicationObject.) |
![]() | ThrowIfDisposedOrImmutable() | Throws an exception if the communication object the State property is not set to the Created state.(Inherited from CommunicationObject.) |
![]() | ThrowIfDisposedOrNotOpen() | Throws an exception if the communication object is not in the Opened state.(Inherited from CommunicationObject.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() | Closed | Occurs when a communication object transitions into the closed state.(Inherited from CommunicationObject.) |
![]() | Closing | Occurs when a communication object transitions into the closing state.(Inherited from CommunicationObject.) |
![]() | Faulted | Occurs when a communication object transitions into the faulted state.(Inherited from CommunicationObject.) |
![]() | Opened | Occurs when a communication object transitions into the opened state.(Inherited from CommunicationObject.) |
![]() | Opening | Occurs when a communication object transitions into the opening state.(Inherited from CommunicationObject.) |
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;
