WorkflowRuntime.GetAllServices Method

Definition

Namespace:

System.Workflow.Runtime

Assembly:

System.Workflow.Runtime.dll

Overloads

GetAllServices(Type)	Retrieves all the services that are added to the workflow run-time engine that implement or derive from the specified Type.
GetAllServices<T>()	Retrieves all the services that are added to the workflow run-time engine that implement or derive from the specified generic type.

GetAllServices(Type)

Retrieves all the services that are added to the workflow run-time engine that implement or derive from the specified Type.

public:
 System::Collections::ObjectModel::ReadOnlyCollection<System::Object ^> ^ GetAllServices(Type ^ serviceType);

public System.Collections.ObjectModel.ReadOnlyCollection<object> GetAllServices (Type serviceType);

member this.GetAllServices : Type -> System.Collections.ObjectModel.ReadOnlyCollection<obj>

Public Function GetAllServices (serviceType As Type) As ReadOnlyCollection(Of Object)

Parameters

serviceType

Type

The Type that services must implement to be returned.

Returns

ReadOnlyCollection<Object>

Services that implement or derive from the specified Type.

Exceptions

ArgumentNullException

serviceType is a null reference (Nothing in Visual Basic).

ObjectDisposedException

The WorkflowRuntime is disposed.

Examples

The following example demonstrates how to retrieve all services of a given type from a WorkflowRuntime object.

// Create a new workflow runtime
WorkflowRuntime workflowRuntime = new WorkflowRuntime();
// Obtain the type of the TrackingService abstract class
Type serviceType = typeof(TrackingService);
// Create a services collection
ReadOnlyCollection<object> services;
// Fetch a collection of all services that match the given type
services = workflowRuntime.GetAllServices(serviceType);

' Create a new workflow runtime
Dim workflowRuntime As New WorkflowRuntime()
' Obtain the type of the TrackingService abstract class
Dim serviceType As Type = GetType(TrackingService)
' Create a services collection
Dim services As ReadOnlyCollection(Of Object)
' Fetch a collection of all services that match the given type
services = workflowRuntime.GetAllServices(serviceType)

Remarks

An empty ReadOnlyCollection<T> indicates that no services that implement or derive from the specified Type have been added to the workflow run-time engine.

GetAllServices<T>()

Retrieves all the services that are added to the workflow run-time engine that implement or derive from the specified generic type.

public:
generic <typename T>
 System::Collections::ObjectModel::ReadOnlyCollection<T> ^ GetAllServices();

public System.Collections.ObjectModel.ReadOnlyCollection<T> GetAllServices<T> ();

member this.GetAllServices : unit -> System.Collections.ObjectModel.ReadOnlyCollection<'T>

Public Function GetAllServices(Of T) () As ReadOnlyCollection(Of T)

Type Parameters

T

The service type.

Returns

ReadOnlyCollection<T>

Services that implement or derive from the specified generic type.

Exceptions

ObjectDisposedException

The WorkflowRuntime is disposed.

Examples

The following example demonstrates how to retrieve all services of a given type from a WorkflowRuntime object.

// Create a new workflow runtime
WorkflowRuntime workflowRuntime = new WorkflowRuntime();
// Obtain the type of the TrackingService abstract class
Type serviceType = typeof(TrackingService);
// Create a services collection
ReadOnlyCollection<TrackingService> services;
// Fetch a collection of all services that match the given type
services = workflowRuntime.GetAllServices<TrackingService>();

' Create a new workflow runtime
Dim workflowRuntime As New WorkflowRuntime()
' Obtain the type of the TrackingService abstract class
Dim serviceType As Type = GetType(TrackingService)
' Create a services collection
Dim services As ReadOnlyCollection(Of TrackingService)
' Fetch a collection of all services that match the given type
services = workflowRuntime.GetAllServices(Of TrackingService)()

Remarks

An empty ReadOnlyCollection<T> indicates that no services have been added to the workflow run-time engine that implement or derive from the specified generic type.
