SPContentType.WorkflowAssociations - Propriété

Obtient un objet SPWorkflowAssociationCollection qui représente les associations de flux de travail pour ce type de contenu.

Espace de noms :  Microsoft.SharePoint
Assembly :  Microsoft.SharePoint (dans Microsoft.SharePoint.dll)

Syntaxe

'Déclaration
Public ReadOnly Property WorkflowAssociations As SPWorkflowAssociationCollection
    Get
'Utilisation
Dim instance As SPContentType
Dim value As SPWorkflowAssociationCollection

value = instance.WorkflowAssociations
public SPWorkflowAssociationCollection WorkflowAssociations { get; }

Valeur de propriété

Type : Microsoft.SharePoint.Workflow.SPWorkflowAssociationCollection
La collection de flux de travail associé au type de contenu.

Remarques

La propriété WorkflowAssociations retourne un objet SPWorkflowAssociationCollection avec une collection du type de contenu des associations de flux de travail. Vous pouvez récupérer une association à partir de la collection à l'aide de la valeur de la propriété Id en tant qu'indexeur ou en passant le nom de l'association flux de travail à la méthode GetAssociationByName .

Chaque association de flux de travail dans une collection doit avoir une valeur unique dans la propriété Name . Lorsque vous ajoutez une nouvelle association de flux de travail, vous devez le tester pour voir si une flux de travail association portant ce nom existe déjà dans la collection. Si l'association de flux de travail est déjà un membre de la collection et que vous souhaitez mettre à jour l'association existante, appelez la méthode Update à la place.

Vous pouvez tester l'existence d'une association de flux de travail dans une collection du type de contenu en appelant la méthode GetAssociationByName . Si la valeur de retour de cette méthode n'est pas une référence Null (Rien dans Visual Basic), l'association est déjà dans la collection. L'exemple suivant illustre cette technique.

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);
}

Exemples

L'exemple suivant est une application console qui crée une association de flux de travail et l'ajoute à la collection du type de contenu de site des associations de flux de travail puis propage la modification aux enfants du type de contenu.
