定义

命名空间:

System.Workflow.Runtime.Hosting

程序集:

System.Workflow.Runtime.dll

从其序列化的窗体中还原 Activity。

protected:
 static System::Workflow::ComponentModel::Activity ^ RestoreFromDefaultSerializedForm(cli::array <System::Byte> ^ activityBytes, System::Workflow::ComponentModel::Activity ^ outerActivity);

protected static System.Workflow.ComponentModel.Activity RestoreFromDefaultSerializedForm (byte[] activityBytes, System.Workflow.ComponentModel.Activity outerActivity);

static member RestoreFromDefaultSerializedForm : byte[] * System.Workflow.ComponentModel.Activity -> System.Workflow.ComponentModel.Activity

Protected Shared Function RestoreFromDefaultSerializedForm (activityBytes As Byte(), outerActivity As Activity) As Activity

参数

activityBytes

Byte[]

Activity 的序列化的窗体。

outerActivity

Activity

外部 Activity，其中包含要还原的 Activity。

返回

Activity

已还原的 Activity。

示例

下面的示例演示 RestoreFromDefaultSerializedForm 方法的实现。 此示例摘自 FilePersistenceService.cs 文件中的“自定义持久性服务”示例。 有关详细信息，请参阅 自定义持久性服务示例。

// Load the completed activity state.
protected override Activity LoadCompletedContextActivity(Guid activityId, Activity outerActivity)
{
    Console.WriteLine("Loading completed activity context: {0}", activityId);
    byte[] workflowBytes = DeserializeFromFile(activityId);
    Activity deserializedActivities = WorkflowPersistenceService.RestoreFromDefaultSerializedForm(workflowBytes, outerActivity);
    return deserializedActivities;
}

' Load completed activity state.
Protected Overrides Function LoadCompletedContextActivity(ByVal scopeId As System.Guid, ByVal outerActivity As System.Workflow.ComponentModel.Activity) As System.Workflow.ComponentModel.Activity
    Console.WriteLine("Loading completed activity context: 0}", scopeId)
    Dim workflowBytes As Byte() = DeserializeFromFile(scopeId)
    Dim deserializedActivities As Activity = WorkflowPersistenceService.RestoreFromDefaultSerializedForm(workflowBytes, outerActivity)
    Return deserializedActivities
End Function
