TrackingProfileSerializer.Serialize(TextWriter, TrackingProfile) 方法

定义

命名空间:

System.Workflow.Runtime.Tracking

程序集:

System.Workflow.Runtime.dll

通过使用跟踪配置文件 XML 架构定义 (XSD) 将跟踪配置文件序列化为 XML 文档。

public:
 void Serialize(System::IO::TextWriter ^ writer, System::Workflow::Runtime::Tracking::TrackingProfile ^ profile);

public void Serialize (System.IO.TextWriter writer, System.Workflow.Runtime.Tracking.TrackingProfile profile);

member this.Serialize : System.IO.TextWriter * System.Workflow.Runtime.Tracking.TrackingProfile -> unit

Public Sub Serialize (writer As TextWriter, profile As TrackingProfile)

参数

writer

TextWriter

有效的 TrackingProfile。

profile

TrackingProfile

此方法返回时将包含容纳 XML 文档的 TextWriter。 参数未经初始化即被传递。

例外

ArgumentNullException

profile 为 null。

或

writer 为 null。

ArgumentException

profile 不是有效的跟踪配置文件。

示例

下面的代码示例演示如何使用 TrackingProfileSerializer 构造函数创建 TrackingProfileSerializer，以便序列化 TrackingProfile。 代码还使用 Serialize 方法。

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

序列化是指依据有效的 TrackingProfile 创建格式良好的 XML 文档的过程。 Serialize 使用跟踪配置文件 Schema 来序列化跟踪配置文件。 profile 必须是包含至少一个有效跟踪点的有效 TrackingProfile。 跟踪配置文件验证是在序列化过程中执行的，并且，如果跟踪配置文件无效，则会引发 ArgumentException。 您可以捕获此异常，并检查其消息属性来确定验证错误的原因。 如果在序列化跟踪配置文件时出现任何未经处理的异常，为其请求跟踪配置文件的工作流实例将终止。
