AutomationProperty

範例

以下範例取得該屬性的當前值。

System.Windows.Point clickablePoint = new System.Windows.Point(-1,-1);
object prop = autoElement.GetCurrentPropertyValue(AutomationElement.ClickablePointProperty);
// Do not attempt to cast prop if it is null.
if (prop is System.Windows.Point)
{
    clickablePoint = (System.Windows.Point)prop;
}

Dim clickablePoint As New System.Windows.Point(- 1, - 1)
Dim prop As Object = autoElement.GetCurrentPropertyValue(AutomationElement.ClickablePointProperty)
' Do not attempt to cast prop if it is null.
If TypeOf prop Is System.Windows.Point Then
    clickablePoint = DirectCast(prop, System.Windows.Point)
End If

以下範例取得該屬性的當前值，但指定若元素本身未提供屬性值， NotSupported 則回傳該屬性而非預設值。

System.Windows.Point clickablePoint1;
object clickablePointNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.ClickablePointProperty, true);
if (clickablePointNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    clickablePoint1 = (System.Windows.Point)clickablePointNoDefault;
}

Dim clickablePoint1 As System.Windows.Point
Dim clickablePointNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.ClickablePointProperty, True)
If clickablePointNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    clickablePoint1 = DirectCast(clickablePointNoDefault, System.Windows.Point)
End If
