SPContentType.WorkflowAssociations property

取得表示這個內容類型的工作流程關聯的SPWorkflowAssociationCollection物件。

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'宣告
Public ReadOnly Property WorkflowAssociations As SPWorkflowAssociationCollection
    Get
'用途
Dim instance As SPContentType
Dim value As SPWorkflowAssociationCollection

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

Property value

Type: Microsoft.SharePoint.Workflow.SPWorkflowAssociationCollection
內容類型相關聯的工作流程的集合。

備註

WorkflowAssociations屬性會傳回SPWorkflowAssociationCollection物件與工作流程關聯的內容類型的集合。使用作為索引子的Id屬性的值,或將工作流程關聯的名稱傳遞到GetAssociationByName方法,您可以從集合擷取關聯。

集合中每個工作流程關聯必須有唯一的值, Name屬性中。當您新增新的工作流程關聯時,您應該測試看看是否該名稱的工作流程關聯已經存在於集合中。如果您的工作流程關聯已經是集合的成員,而您想要更新現有的關聯,而是呼叫Update方法。

您可以藉由呼叫GetAssociationByName方法來測試的內容類型的集合中的工作流程關聯存在。如果該方法的傳回值不是a null reference (Nothing in Visual Basic),然後關聯已在集合中。下列範例示範這項技巧。

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);
}

Examples

下列範例是一個主控台應用程式,會建立工作流程關聯、 將它加入至工作流程關聯的站台內容類型的集合,然後再傳播至子系內容類型的變更。
