示例
以下示例检索 属性的当前值。
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
以下示例检索属性的当前值，但指定如果元素本身未为属性提供值， NotSupported 则返回 而不是默认值。
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
