'Uso
Dim instance As SPContentType

public SPWorkflowAssociationCollection WorkflowAssociations { get; }
Valor de propiedad
Tipo: Microsoft.SharePoint.Workflow.SPWorkflowAssociationCollection
La colección de flujos de trabajo asociados con el tipo de contenido.
Comentarios
La propiedad WorkflowAssociations devuelve un objeto SPWorkflowAssociationCollection con la colección del tipo de contenido de las asociaciones de flujo de trabajo. Puede recuperar una asociación de la colección con el valor de la propiedad Id como un indizador o pasando el nombre de la asociación flujo de trabajo para el método GetAssociationByName .
Cada asociación de flujo de trabajo de una colección debe tener un valor único en la propiedad Name . Cuando se agrega una nueva asociación de flujo de trabajo, debe probar para ver si una asociación de flujo de trabajo con ese nombre ya existe en la colección. Si la asociación de flujo de trabajo ya es un miembro de la colección y desea actualizar la asociación existente, llame al método Update en su lugar.
Puede comprobar la existencia de una asociación de flujo de trabajo en la colección del tipo de contenido al llamar al método GetAssociationByName . Si el valor devuelto por este método no es una referencia null (Nothing en Visual Basic), a continuación, la asociación ya está en la colección. En el siguiente ejemplo se muestra esta técnica.
If contentType.WorkflowAssociations.GetAssociationByName(workflowAssociation.Name, site.Locale) Is Nothing Then
contentType.WorkflowAssociations.Add(workflowAssociation)
Else
contentType.WorkflowAssociations.Update(workflowAssociation)
End If
if (contentType.WorkflowAssociations.GetAssociationByName(workflowAssociation.Name, site.Locale) == null)
{
contentType.WorkflowAssociations.Add(workflowAssociation);
}
else
{
contentType.WorkflowAssociations.Update(workflowAssociation);
}
Ejemplos
En el siguiente ejemplo es una aplicación de consola que crea una asociación de flujo de trabajo, lo agrega a la colección de un sitio del tipo de contenido de las asociaciones de flujo de trabajo y, a continuación, se propaga el cambio a los elementos secundarios del tipo de contenido.
