Serializes the tracking profile into an XML document by using the tracking profile XML Schema definition (XSD).

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)

Parameters

writer: TextWriter

A valid TrackingProfile.

profile: TrackingProfile

When this method returns, contains a TextWriter that holds the XML document. The parameter is passed uninitialized.

Exceptions

ArgumentNullException

profile is null.

-or-

writer is null.

ArgumentException

profile is not a valid tracking profile.

Examples

The following code example demonstrates how you can create a TrackingProfileSerializer using the TrackingProfileSerializer constructor to serialize a TrackingProfile. The code also uses the Serialize method.

This code example is part of the Query using SQLTrackingService SDK sample from the Program.cs file. For more information, see Query Using SQLTrackingService.

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

Remarks

Serialization refers to the process of creating a well-formed XML document from a valid TrackingProfile. Serialize uses the tracking profile Schema to serialize the tracking profile. profile must be a valid TrackingProfile that contains at least one valid track point. Validation on the tracking profile is performed during serialization, and, if the tracking profile is not valid, an ArgumentException is thrown. You can catch this exception and examine its message property to determine the cause of the validation error. If there are any unhandled exceptions while serializing the tracking profile, then the workflow instance for which the tracking profile was requested is terminated.
