SharePoint：在StartWorkflow（）終止後訪問工作流變量

Question

我通過調用workflowManager.StartWorkflow（）從SharePoint事件接收器以編程方式運行SharePoint工作流。

工作流程是在執行期間設置一些工作流變量。有沒有辦法在工作流程終止後訪問這些變量的最後一個值（例如，對StartWorkflow（）的調用返回）？

以下是一個演示我的意圖我的示例代碼：

public override void ItemAdded(SPItemEventProperties properties) 
    { 
     SPWorkflow workflow = null; 
     SPWorkflowManager workflowManager = null; 
     try 
     { 
      base.ItemAdded(properties); 

      workflowManager = properties.OpenWeb().Site.WorkflowManager; 
      var workflowAssociation = properties.ListItem.ParentList.WorkflowAssociations[0]; 

      workflow = workflowManager.StartWorkflow(properties.ListItem, workflowAssociation, "<Data></Data>"); 

      // I can read any fields that were updated by the WF 
      SPListItem item = properties.ListItem.ParentList.GetItemById(properties.ListItemId); 
      string validationResult = (string) item["ValidationResult"]; 

      // how can I access any workflow variables created during execution? 
     } 
     catch (Exception ex) 
     { 
      Debug.WriteLine(ex); 
      if (workflow != null && workflowManager != null) 
      { 
       SPWorkflowManager.CancelWorkflow(workflow); 
      } 
      throw; 
     } 
    } 

Answer 1

他們也許寫出來的名單？這可能是你最麻煩的選擇。

另外，還有一個SPWorkflow.Xml屬性「返回一個表示XML格式的工作流實例的字符串」，但我從未嘗試過。雖然將它傳回SharePoint可能會很尷尬。
