示例

以下示例演示如何处理 事件 PropertyDataChanged 。 此示例假定有 一个 Guid 调用 dateTimeGuid 的 PropertyDataChanged ，并且事件已连接到此示例中定义的事件处理程序。

void Strokes_PropertyDataChanged(object sender, PropertyDataChangedEventArgs e)
{
    if ((e.PropertyGuid == dateTimeGuid) && (e.NewValue is DateTime))
    {
        MessageBox.Show("The timestamp for the strokes is " +
            ((DateTime)e.NewValue).ToString());
    }
}

Private Sub Strokes_PropertyDataChanged(ByVal sender As Object, _
    ByVal e As PropertyDataChangedEventArgs)

    If (e.PropertyGuid = dateTimeGuid) And (TypeOf e.NewValue Is DateTime) Then
        MessageBox.Show("The timestamp for the strokes is " & _
            (CType(e.NewValue, DateTime)).ToString())
    End If

End Sub
