InstanceContext Class
.NET Framework 4.5
Represents the context information for a service instance.
Namespace:
System.ServiceModel
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The InstanceContext type exposes the following members.
| Name | Description | |
|---|---|---|
  | InstanceContext(Object) | Initializes a new instance of the InstanceContext class for a specified object that implements the service instance. |
| InstanceContext(ServiceHostBase) | Initializes a new instance of the InstanceContext class for a service hosted by a specified host. |
| 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. |
| Name | Description | |
|---|---|---|
| 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. |
| 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. |
| Name | Description | |
|---|---|---|
| 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 | Completes an asynchronous operation to close a communication object. (Inherited from CommunicationObject.) |
| EndOpen | 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 a hash function for a particular type. (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 | 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;
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
