TrackingProfileSerializer.Serialize(TextWriter, TrackingProfile) 方法

定義

命名空間:

System.Workflow.Runtime.Tracking

組件:

System.Workflow.Runtime.dll

使用追蹤設定檔 XML 結構描述定義 (XSD) 將追蹤設定檔序列化為 XML 文件。

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)

參數

writer

TextWriter

有效的 TrackingProfile。

profile

TrackingProfile

當這個方法傳回時，包含存有 XML 文件的 TextWriter。 參數是以未初始化的狀態傳遞。

例外狀況

ArgumentNullException

profile 為 null。

-或-

writer 為 null。

ArgumentException

profile 不是有效的追蹤設定檔。

範例

下列程式碼範例將示範如何使用 TrackingProfileSerializer 建構函式建立 TrackingProfileSerializer 以序列化 TrackingProfile。 此程式碼也會使用 Serialize 方法。

這個程式碼範例是 Program.cs 檔案中＜使用 SQLTrackingService 查詢 SDK＞範例的一部分。 如需詳細資訊，請參閱 使用 SQLTrackingService 查詢。

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

備註

序列化是指從有效的 TrackingProfile 建立格式正確的 XML 文件的程序。 Serialize 會使用追蹤設定檔 Schema，將追蹤設定檔序列化。 profile 必須是有效的 TrackingProfile，包含至少一個有效的追蹤點。 序列化期間會在追蹤設定檔上執行驗證，如果追蹤設定檔無效，則擲回 ArgumentException。 您可以捕捉此例外狀況，並檢查它的訊息屬性以判斷驗證錯誤的原因。 如果在序列化追蹤設定檔的期間有任何未處理的例外狀況，將終止要求追蹤設定檔的工作流程執行個體。
