Esempio: impostare lo stato di un flusso di lavoro
Data di pubblicazione: gennaio 2017
Si applica a: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Questo codice di esempio è per Microsoft Dynamics 365 (online e locale).Scarica il pacchetto SDK di Microsoft Dynamics CRM. È disponibile nel percorso seguente nel pacchetto di download:
SampleCode\CS\Process\Workflows\SetStateWorkflow.cs
Requisiti
Per ulteriori informazioni sui requisiti per l'esecuzione del codice di esempio fornito nell'SDK, vedi Utilizzare il codice di esempio e dell'helper.
Dimostra
In questo esempio vengono illustrate le procedure per modificare lo stato di un flusso di lavoro, attivandolo e disattivandolo, utilizzando il messaggio SetStateRequest. Inoltre, nell'esempio vengono illustrate le procedure per creare un flusso di lavoro personalizzato XAML. Un frammento di codice che visualizza solo le sezioni principali dell'esempio viene visualizzato per primo, seguito da Codice di esempio completo.
Esempio
Frammento di codice che visualizza come attivare e disattivare un flusso di lavoro.
var activateRequest = new SetStateRequest
{
EntityMoniker = new EntityReference
(Workflow.EntityLogicalName, _workflowId),
State = new OptionSetValue((int)WorkflowState.Activated),
Status = new OptionSetValue((int)workflow_statuscode.Activated)
};
_serviceProxy.Execute(activateRequest);
SetStateRequest deactivateRequest = new SetStateRequest
{
EntityMoniker =
new EntityReference(Workflow.EntityLogicalName, _workflowId),
State = new OptionSetValue((int)WorkflowState.Draft),
Status = new OptionSetValue((int)workflow_statuscode.Draft)
};
_serviceProxy.Execute(deactivateRequest);
Esempio
Frammento di codice che visualizza come creare un flusso di lavoro XAML.
Workflow workflow = new Workflow()
{
Name = "CreateTaskXAML",
Type = new OptionSetValue((int)WorkflowType.Definition),
Category = new OptionSetValue((int)WorkflowCategory.Workflow),
Scope = new OptionSetValue((int)WorkflowScope.User),
LanguageCode = 1033, // U.S. English
TriggerOnCreate = true,
OnDemand = true,
PrimaryEntity = Lead.EntityLogicalName,
Description =
"Test workflow for the SetStateWorkflow SDK sample",
Xaml = xamlWF
};
_workflowId = _serviceProxy.Create(workflow);
Per il codice XAML che definisce il flusso di lavoro, vedere Codice di esempio completo.
