TrackingProfile.ActivityTrackPoints 属性

定义

命名空间:

System.Workflow.Runtime.Tracking

程序集:

System.Workflow.Runtime.dll

获取运行时跟踪基础结构用于筛选活动状态事件的活动跟踪点的集合。

public:
 property System::Workflow::Runtime::Tracking::ActivityTrackPointCollection ^ ActivityTrackPoints { System::Workflow::Runtime::Tracking::ActivityTrackPointCollection ^ get(); };

public System.Workflow.Runtime.Tracking.ActivityTrackPointCollection ActivityTrackPoints { get; }

member this.ActivityTrackPoints : System.Workflow.Runtime.Tracking.ActivityTrackPointCollection

Public ReadOnly Property ActivityTrackPoints As ActivityTrackPointCollection

属性值

ActivityTrackPointCollection

一个指定工作流实例中各个点的 ActivityTrackPointCollection，运行时跟踪基础结构应为该工作流实例将 ActivityTrackingRecord 发送到跟踪服务。

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

当活动实例的 ActivityExecutionStatus 发生更改时，工作流实例会将活动状态事件发出到运行时跟踪基础结构。 运行时跟踪基础结构使用 ActivityTrackPoints 属性筛选这些活动状态事件，以确定何时将 ActivityTrackingRecord 发送到跟踪服务。 您可以将 ActivityTrackPoint 添加到 ActivityTrackPoints 属性，以指定工作流实例的可能执行路径中的关注点，您想要运行时基础结构为该工作流实例发送一个 ActivityTrackingRecord。

ActivityTrackPoint 不会实际在工作流实例中定义一个物理点，而是会定义一组匹配参数，运行时跟踪基础结构可以使用这些参数来匹配应为其发送 ActivityTrackingRecord 的活动状态事件。 因此，在工作流实例的生存期内，可以匹配同一个 ActivityTrackPoint 多次。 ActivityTrackPoint 还可以指定要从工作流实例中提取并在 ActivityTrackingRecord 中返回的数据。
