TrackingProfile.ActivityTrackPoints 属性

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

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。
