範例

下列範例示範如何使用 Current 屬性來擷取清單中已選取的專案名稱。

/// <summary>
/// Handles ElementSelected events by showing a message.
/// </summary>
/// <param name="src">Object that raised the event; in this case, a list item.</param>
/// <param name="e">Event arguments.</param>
private void OnSelect(object src, AutomationEventArgs e)
{
    // Get the name of the item, which is equivalent to its text.
    AutomationElement element = src as AutomationElement;
    if (element != null)
    {
        Console.WriteLine(element.Current.Name + " was selected.");
    }
}

''' <summary>
''' Handles ElementSelected events by showing a message.
''' </summary>
''' <param name="src">Object that raised the event; in this case, a list item.</param>
''' <param name="e">Event arguments.</param>
Private Sub OnSelect(ByVal src As Object, ByVal e As AutomationEventArgs)
    ' Get the name of the item, which is equivalent to its text.
    Dim element As AutomationElement = DirectCast(src, AutomationElement)
    If (element IsNot Nothing) Then
        Console.WriteLine(element.Current.Name + " was selected.")
    End If

End Sub

備註

消費者介面自動化屬性的存取子會表示為 所 Current 傳回結構的屬性。 您不需要擷取 結構;您可以直接存取其成員，如下列範例所示。 如需可用屬性及其使用的特定資訊，請參閱 AutomationElement.AutomationElementInformation 。

若要取得這個專案上消費者介面自動化屬性的快取值，請使用 Cached 屬性。
