Exemples

Dans cet exemple, chaque objet Stroke d'une collection Strokes est examiné. Si le ExtendedProperties du Stroke contient des propriétés associées à des objets Guid d'horodatage spécial, le ExtendedProperty est supprimé de la collection.

Private Sub RemoveAllTimeStampProperties()
    ' STROKE_START_GUID and STROKE_END_GUID
    ' are class level string const set via GUID generator
    Dim strokeStartGuid As Guid = New Guid(STROKE_START_GUID)
    Dim strokeEndGuid As Guid = New Guid(STROKE_END_GUID)

    ' access the Strokes property via using statement
    ' to insure that the object mStrokes is disposed when finished
    ' Otherwise, you will have a memory leak
    Using mStrokes As Strokes = mInkObject.Ink.Strokes
        For Each S As Stroke In mStrokes
            If S.ExtendedProperties.Contains(strokeStartGuid) Then
                S.ExtendedProperties.Remove(strokeStartGuid)
            End If
            If S.ExtendedProperties.Contains(strokeEndGuid) Then
                S.ExtendedProperties.Remove(strokeEndGuid)
            End If
        Next
    End Using
End Sub

private void RemoveAllTimeStampProperties()
{
    // STROKE_START_GUID and STROKE_END_GUID
    // are class level string const set via GUID generator
    Guid strokeStartGuid = new Guid(STROKE_START_GUID);
    Guid strokeEndGuid = new Guid(STROKE_END_GUID);

    // access the Strokes property via using statement
    // to insure that the object mStrokes is disposed when finished
    // Otherwise, you will have a memory leak
    using (Strokes mStrokes = mInkObject.Ink.Strokes)
    {
        foreach (Stroke S in mStrokes)
        {
            if (S.ExtendedProperties.Contains(strokeStartGuid))
            {
                S.ExtendedProperties.Remove(strokeStartGuid);
            }
            if (S.ExtendedProperties.Contains(strokeEndGuid))
            {
                S.ExtendedProperties.Remove(strokeEndGuid);
            }
        }
