ActivityTrackPoint.MatchingLocations 屬性

定義

命名空間:

System.Workflow.Runtime.Tracking

組件:

System.Workflow.Runtime.dll

取得應由執行階段追蹤基礎結構包含在追蹤點比對內的位置集合。

public:
 property System::Workflow::Runtime::Tracking::ActivityTrackingLocationCollection ^ MatchingLocations { System::Workflow::Runtime::Tracking::ActivityTrackingLocationCollection ^ get(); };

public System.Workflow.Runtime.Tracking.ActivityTrackingLocationCollection MatchingLocations { get; }

member this.MatchingLocations : System.Workflow.Runtime.Tracking.ActivityTrackingLocationCollection

Public ReadOnly Property MatchingLocations As ActivityTrackingLocationCollection

屬性值

ActivityTrackingLocationCollection

ActivityTrackingLocationCollection，指定要為追蹤點比對的位置。 預設為空集合。

範例

下列範例示範存取 MatchingLocations 屬性。 這個範例來自＜TrackingProfileDesigner SDK＞範例。 如需詳細資訊，請參閱 追蹤設定檔設計工具範例。

/// <summary>
/// Saves a tracking condition for an activity
/// </summary>
/// <param name="activity"></param>
/// <param name="key"></param>

internal void SaveTrackingCondition(Activity activity, ref ActivityTrackingCondition key, string member, ComparisonOperator op, string value)
{
    ActivityTrackPoint trackPoint = GetTrackPointForActivity(activity);
    if (trackPoint != null)
    {
        if (key == null)
        {
            key = new ActivityTrackingCondition();
            trackPoint.MatchingLocations[0].Conditions.Add(key);
        }
        key.Member = member;
        key.Value = value;
        key.Operator = op;
    }
}

' Saves a tracking condition for an activity
' <param name="activity"></param>
' <param name="key"></param>
' <param name="member"></param>
' <param name="op"></param>
' <param name="value"></param>
Friend Sub SaveTrackingCondition(ByVal activity As Activity, ByRef key As ActivityTrackingCondition, ByVal member As String, ByVal op As ComparisonOperator, ByVal value As String)
    Dim trackPoint As ActivityTrackPoint = GetTrackPointForActivity(activity)
    If trackPoint IsNot Nothing Then
        If (key Is Nothing) Then
            key = New ActivityTrackingCondition()
            trackPoint.MatchingLocations(0).Conditions.Add(key)
        End If
        key.Member = member
        key.Value = value
        key.Operator = op
    End If
End Sub

備註

如果 MatchingLocations 是空白，執行階段追蹤基礎結構就無法比對追蹤點。 您必須加入至少一個 ActivityTrackingLocation 至 MatchingLocations 的 ActivityTrackPoint 才可以參與比對。

如果 ActivityTrackingLocation 中的任何 MatchingLocations 由執行階段追蹤基礎結構比對相符，且 ActivityTrackingLocation 中的所有 ExcludedLocations 都不相符，將會比對追蹤點。
