WorkflowQueuingService Class
Provides the services for management of WorkflowQueue objects.
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
The following code example demonstrates a method, named CreateQueue, that initializes a WorkflowQueuingService object by calling the ActivityExecutionContext.GetService method. The code then uses the Exists method to determine if a WorkflowQueue with a specified name exists. If it does not exist, the code calls the CreateWorkflowQueue method; if it does the code calls the GetWorkflowQueue method.
This code example is part of the File Watcher Activity SDK Sample from the FileSystemEvent.cs file. For more information, see File System Watcher Activity.
Private Function CreateQueue(ByVal context As ActivityExecutionContext) As WorkflowQueue Console.WriteLine("CreateQueue") Dim qService As WorkflowQueuingService = context.GetService(Of WorkflowQueuingService)() If Not qService.Exists(Me.queueName) Then qService.CreateWorkflowQueue(Me.queueName, True) End If Return qService.GetWorkflowQueue(Me.QueueName) End Function
