Esempio

Nell'esempio di codice seguente viene illustrata la creazione di un'attività While .

new While
{
    Condition = true,
    Body = new Receive
    {
        ServiceContractName = Constants.POContractName,
        OperationName = Constants.UpdatePOName,
        CorrelatesWith = poidHandle, // identifies that the UpdatePO operation is waiting on the PurchaseOrderId that was used to initialize this handle
        CorrelatesOn = new MessageQuerySet // the query that is used on an incoming message to find the requisite PurchaseOrderId specified in the correlation
        {
            // Id is the name of the incoming parameter within the PurchaseOrder
            { "PoId", new XPathMessageQuery("sm:body()/defns:PurchaseOrder/defns:Id", Constants.XPathMessageContext) }
        },
        Content = ReceiveContent.Create(new OutArgument<PurchaseOrder>(po)) // creates a ReceiveMessageContent
    }
},

public:
 While(System::Activities::Activity<bool> ^ condition);

public While(System.Activities.Activity<bool> condition);

new System.Activities.Statements.While : System.Activities.Activity<bool> -> System.Activities.Statements.While

Public Sub New (condition As Activity(Of Boolean))
