Important

| 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. |
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
Returns
Services that implement or derive from the specified Type.
Exceptions
serviceType is a null reference (Nothing in Visual Basic).
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.
