TrackingProfile.Version 属性

定义

命名空间:

System.Workflow.Runtime.Tracking

程序集:

System.Workflow.Runtime.dll

获取或设置跟踪配置文件的版本。

public:
 property Version ^ Version { Version ^ get(); void set(Version ^ value); };

public Version Version { get; set; }

member this.Version : Version with get, set

Public Property Version As Version

属性值

Version

Version 的 TrackingProfile。

示例

下面的代码示例演示如何使用 TrackingProfile 构造函数创建 TrackingProfile，以及如何使用对象的属性来帮助跟踪工作流的执行。 该示例代码使用 ActivityTrackPoints、Version 和 WorkflowTrackPoints 属性。

此代码示例摘自 Program.cs 文件中的“使用 SQLTrackingService 查询”SDK 示例。 有关详细信息，请参阅 使用 SQLTrackingService 进行查询。

private static void CreateAndInsertTrackingProfile()
{
    TrackingProfile profile = new TrackingProfile();
    ActivityTrackPoint activityTrack = new ActivityTrackPoint();
    ActivityTrackingLocation activityLocation = new ActivityTrackingLocation(typeof(Activity));
    activityLocation.MatchDerivedTypes = true;
    IEnumerable<ActivityExecutionStatus> statuses = Enum.GetValues(typeof(ActivityExecutionStatus)) as IEnumerable<ActivityExecutionStatus>;
    foreach (ActivityExecutionStatus status in statuses)
    {
        activityLocation.ExecutionStatusEvents.Add(status);
    }

    activityTrack.MatchingLocations.Add(activityLocation);
    profile.ActivityTrackPoints.Add(activityTrack);
    profile.Version = version;

    WorkflowTrackPoint workflowTrack = new WorkflowTrackPoint();
    WorkflowTrackingLocation workflowLocation = new WorkflowTrackingLocation();
    IEnumerable<TrackingWorkflowEvent> eventStatuses = Enum.GetValues(typeof(TrackingWorkflowEvent)) as IEnumerable<TrackingWorkflowEvent>;
    foreach (TrackingWorkflowEvent status in eventStatuses)
    {
        workflowLocation.Events.Add(status);
    }

    workflowTrack.MatchingLocation = workflowLocation;
    profile.WorkflowTrackPoints.Add(workflowTrack);

    TrackingProfileSerializer serializer = new TrackingProfileSerializer();
    StringWriter writer = new StringWriter(new StringBuilder(), CultureInfo.InvariantCulture);
    serializer.Serialize(writer, profile);
    string trackingprofile = writer.ToString();
    InsertTrackingProfile(trackingprofile);
}

Shared Sub CreateAndInsertTrackingProfile()
    Dim profile As TrackingProfile = New TrackingProfile()

    Dim activityTrack As ActivityTrackPoint = New ActivityTrackPoint()
    Dim activityLocation As ActivityTrackingLocation = New ActivityTrackingLocation(GetType(Activity))
    activityLocation.MatchDerivedTypes = True
    Dim statuses As IEnumerable(Of ActivityExecutionStatus) = CType(System.Enum.GetValues(GetType(ActivityExecutionStatus)), IEnumerable(Of ActivityExecutionStatus))
    For Each status As ActivityExecutionStatus In statuses
        activityLocation.ExecutionStatusEvents.Add(status)
    Next

    activityTrack.MatchingLocations.Add(activityLocation)
    profile.ActivityTrackPoints.Add(activityTrack)
    profile.Version = version

    Dim workflowTrack As WorkflowTrackPoint = New WorkflowTrackPoint()
    Dim workflowLocation As WorkflowTrackingLocation = New WorkflowTrackingLocation()
    Dim eventStatuses As IEnumerable(Of TrackingWorkflowEvent) = CType(System.Enum.GetValues(GetType(TrackingWorkflowEvent)), IEnumerable(Of TrackingWorkflowEvent))
    For Each status As TrackingWorkflowEvent In eventStatuses
        workflowLocation.Events.Add(status)
    Next

    workflowTrack.MatchingLocation = workflowLocation
    profile.WorkflowTrackPoints.Add(workflowTrack)

    Dim serializer As TrackingProfileSerializer = New TrackingProfileSerializer()
    Dim writer As StringWriter = New StringWriter(New StringBuilder(), CultureInfo.InvariantCulture)
    serializer.Serialize(writer, profile)
    Dim trackingProfile As String = writer.ToString()
    InsertTrackingProfile(trackingProfile)
End Sub

注解

由于工作流运行时引擎中配置文件缓存的语义的原因，如果更改 TrackingProfile 的内容，您必须更新 Version。 如果不更新，则工作流运行时引擎可能不会加载更新的 TrackingProfile，即使它是通过调用 TrackingService.TryReloadProfile 返回的，或者在与 ProfileUpdatedEventArgs 事件关联的 ProfileUpdated 中发送的。 因此，为了确保工作流运行时引擎加载更新的 TrackingProfile，您应为 Version 更改 TrackingProfile。 您可以在任何适当的工作流实例上显式调用 WorkflowInstance.ReloadTrackingProfiles，或者，视实现而定，您可以依赖于跟踪服务将更改通知工作流运行时引擎。 有关详细信息，请参阅 TrackingService。
