範例

下列範例將示範如何呼叫 WorkflowInstance 物件的 ApplyWorkflowChanges。 這個範例是 Mainform.cs 的檔案中＜訂購狀態機器 SDK＞範例的一部分。 如需詳細資訊，請參閱 排序狀態機器範例。

// Apply the changes to the workflow instance
try
{
    instance.ApplyWorkflowChanges(changes);
}
catch (WorkflowValidationFailedException)
{
    // New state has already been added
    MessageBox.Show("On Hold state has already been added to this workflow.");
}

' Apply the changes to the workflow instance
Try
    instance.ApplyWorkflowChanges(changes)
Catch e As WorkflowValidationFailedException
    ' New state has already been added
    MessageBox.Show("On Hold state has already been added to this workflow.")
End Try

備註

如果工作流程執行個體尚未暫止，在套用變更之前，工作流程執行階段引擎會暫時停止執行個體。
