public void Load(System.Activities.WorkflowApplicationInstance instance);
member this.Load : System.Activities.WorkflowApplicationInstance -> unit
Public Sub Load (instance As WorkflowApplicationInstance)

參數

WorkflowApplicationInstance

那個實例。

適用於

Load(Guid)

將指定的工作流程實例從實例儲存載入記憶體。

public:
 void Load(Guid instanceId);
public void Load(Guid instanceId);
member this.Load : Guid -> unit
Public Sub Load (instanceId As Guid)

範例

以下範例 Load 呼叫從 SqlWorkflowInstanceStore.

string input = Console.ReadLine();

WorkflowApplication application = new WorkflowApplication(activity);
application.InstanceStore = instanceStore;

application.Completed = (workflowApplicationCompletedEventArgs) =>
{
    Console.WriteLine("\nWorkflowApplication has Completed in the {0} state.", workflowApplicationCompletedEventArgs.CompletionState);
};

application.Unloaded = (workflowApplicationEventArgs) =>
{
    Console.WriteLine("WorkflowApplication has Unloaded\n");
    instanceUnloaded.Set();
};

application.Load(id);

//this resumes the bookmark setup by readline
application.ResumeBookmark(readLineBookmark, input);

instanceUnloaded.WaitOne();

適用於

Load(WorkflowApplicationInstance, DynamicUpdateMap)

instance
WorkflowApplicationInstance

那個實例。

timeout

Public Sub Load (instanceId As Guid, timeout As TimeSpan)

參數

instanceId
Guid

一個全球唯一的 128 位元工作流程識別碼。

timeout
TimeSpan

載入操作必須完成的間隔，然後會取消載入操作並拋出 a TimeoutException 。
