Esempio

Nell'esempio di codice seguente viene illustrato un metodo, denominato CreateQueue, che inizializza un oggetto WorkflowQueuingService chiamando il metodo ActivityExecutionContext.GetService.The following code example demonstrates a method, named CreateQueue, that initializes a WorkflowQueuingService object by calling the ActivityExecutionContext.GetService method. Il codice quindi utilizza il metodo Exists per determinare se esiste una classe WorkflowQueue con un nome specificato.The code then uses the Exists method to determine if a WorkflowQueue with a specified name exists. Se non esiste, il codice chiama il metodo CreateWorkflowQueue, altrimenti chiama il metodo GetWorkflowQueue.If it does not exist, the code calls the CreateWorkflowQueue method; if it does the code calls the GetWorkflowQueue method.

Questo esempio di codice fa parte dell'esempio SDK File Watcher Activity nel file FileSystemEvent.cs.This code example is part of the File Watcher Activity SDK Sample from the FileSystemEvent.cs file. Per ulteriori informazioni, vedere attività Watcher del file System.For more information, see File System Watcher Activity.

private WorkflowQueue CreateQueue(ActivityExecutionContext context)
{
    Console.WriteLine("CreateQueue");
    WorkflowQueuingService qService = context.GetService<WorkflowQueuingService>();

    if (!qService.Exists(this.QueueName))
    {
        qService.CreateWorkflowQueue(this.QueueName, true);
    }

    return qService.GetWorkflowQueue(this.QueueName);
}

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
