ServicedComponent Class
Represents the base class of all classes using COM+ services.
System::MarshalByRefObject
System::ContextBoundObject
System.EnterpriseServices::ServicedComponent
System.EnterpriseServices.CompensatingResourceManager::Compensator
System.EnterpriseServices::RegistrationHelperTx
Assembly: System.EnterpriseServices (in System.EnterpriseServices.dll)
The ServicedComponent type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Activate | Called by the infrastructure when the object is created or allocated from a pool. Override this method to add custom initialization code to objects. |
![]() | CanBePooled | This method is called by the infrastructure before the object is put back into the pool. Override this method to vote on whether the object is put back into the pool. |
![]() | Construct | Called by the infrastructure just after the constructor is called, passing in the constructor string. Override this method to make use of the construction string value. |
![]() | CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
![]() | Deactivate | Called by the infrastructure when the object is about to be deactivated. Override this method to add custom finalization code to objects when just-in-time (JIT) compiled code or object pooling is used. |
![]() | Dispose() | Releases all resources used by the ServicedComponent. |
![]() | Dispose(Boolean) | Releases the unmanaged resources used by the ServicedComponent and optionally releases the managed resources. |
![]() ![]() | DisposeObject | Finalizes the object and removes the associated COM+ reference. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
![]() | MemberwiseClone() | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | IRemoteDispatch::RemoteDispatchAutoDone | Ensures that, in the COM+ context, the ServicedComponent class object's done bit is set to true after a remote method invocation |
![]() ![]() | IRemoteDispatch::RemoteDispatchNotAutoDone | Does not ensure that, in the COM+ context, the ServicedComponent class object's done bit is set to true after a remote method invocation. |
![]() ![]() | IServicedComponentInfo::GetComponentInfo | Obtains information about the ServicedComponent class instance. |
Under certain conditions, a class that is derived from ServicedComponent that runs in a COM+ application may stop responding. This problem is caused by an Activity deadlock. Activities can deadlock on multithreaded applications because of an asynchronous cleanup of component references. To work around this problem, call the Dispose method when you complete work with objects derived from ServicedComponent. For more information, see http://support.microsoft.com/default.aspx?scid=kb;en-us;327443.

|---|
Client code must call Dispose on serviced components to ensure proper operation. |
The following code example demonstrates how to expose a class as a configured COM component.
To deploy this class as a configured COM component, you must generate a strong key, compile the class as a library, and register the library. These three steps are accomplished by the following three commands.
sn -k Calculator.snk csc /t:library Calculator.cs regsvcs Calculator.dll
