InstanceContext Class

 

Represents the context information for a service instance.

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


public sealed class InstanceContext : CommunicationObject, IExtensibleObject<InstanceContext>

NameDescription
System_CAPS_pubmethodInstanceContext(Object)

Initializes a new instance of the InstanceContext class for a specified object that implements the service instance.

System_CAPS_pubmethodInstanceContext(ServiceHostBase)

Initializes a new instance of the InstanceContext class for a service hosted by a specified host.

System_CAPS_pubmethodInstanceContext(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.

NameDescription
System_CAPS_pubpropertyExtensions

Gets the extension collection, if any, associated with the service instance.

System_CAPS_pubpropertyHost

Gets the host for the service instance.

System_CAPS_pubpropertyIncomingChannels

Gets the sessionful channels that are incoming to the service instance.

System_CAPS_pubpropertyManualFlowControlLimit

Gets or sets a limit on the number of messages that can be processed by the instance context.

System_CAPS_pubpropertyOutgoingChannels

Gets the sessionful channels that are outgoing from the service instance.

System_CAPS_pubpropertyState

Gets a value that indicates the current state of the communication object.(Inherited from CommunicationObject.)

System_CAPS_pubpropertySynchronizationContext

Gets or sets the context used for thread synchronization with the current instance context.

NameDescription
System_CAPS_pubmethodAbort()

Causes a communication object to transition immediately from its current state into the closing state.(Inherited from CommunicationObject.)

System_CAPS_pubmethodBeginClose(AsyncCallback, Object)

Begins an asynchronous operation to close a communication object.(Inherited from CommunicationObject.)

System_CAPS_pubmethodBeginClose(TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to close a communication object with a specified timeout.(Inherited from CommunicationObject.)

Begins an asynchronous operation to open a communication object.(Inherited from CommunicationObject.)

System_CAPS_pubmethodBeginOpen(TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to open a communication object within a specified interval of time.(Inherited from CommunicationObject.)

System_CAPS_pubmethodClose()

Causes a communication object to transition from its current state into the closed state.(Inherited from CommunicationObject.)

System_CAPS_pubmethodClose(TimeSpan)

Causes a communication object to transition from its current state into the closed state within a specified interval of time.(Inherited from CommunicationObject.)

System_CAPS_pubmethodEndClose(IAsyncResult)

Completes an asynchronous operation to close a communication object.(Inherited from CommunicationObject.)

System_CAPS_pubmethodEndOpen(IAsyncResult)

Completes an asynchronous operation to open a communication object.(Inherited from CommunicationObject.)

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetServiceInstance()

Returns the instance of the service for the instance context.

System_CAPS_pubmethodGetServiceInstance(Message)

Returns the instance of the service for the instance context in response to an incoming message.

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIncrementManualFlowControlLimit(Int32)

Increases the number of messages that can be processed by the service instance.

System_CAPS_pubmethodOpen()

Causes a communication object to transition from the created state into the opened state.(Inherited from CommunicationObject.)

System_CAPS_pubmethodOpen(TimeSpan)

Causes a communication object to transition from the created state into the opened state within a specified interval of time.(Inherited from CommunicationObject.)

System_CAPS_pubmethodReleaseServiceInstance()

Releases the service instance.

System_CAPS_protmethodThrowIfDisposed()

Throws an exception if the communication object is disposed.(Inherited from CommunicationObject.)

System_CAPS_protmethodThrowIfDisposedOrImmutable()

Throws an exception if the communication object the State property is not set to the Created state.(Inherited from CommunicationObject.)

System_CAPS_protmethodThrowIfDisposedOrNotOpen()

Throws an exception if the communication object is not in the Opened state.(Inherited from CommunicationObject.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubeventClosed

Occurs when a communication object transitions into the closed state.(Inherited from CommunicationObject.)

System_CAPS_pubeventClosing

Occurs when a communication object transitions into the closing state.(Inherited from CommunicationObject.)

System_CAPS_pubeventFaulted

Occurs when a communication object transitions into the faulted state.(Inherited from CommunicationObject.)

System_CAPS_pubeventOpened

Occurs when a communication object transitions into the opened state.(Inherited from CommunicationObject.)

System_CAPS_pubeventOpening

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;
