範例

下列範例會抓取屬性的目前值。The following example retrieves the current value of the property. 如果元素未提供預設值,則會傳回預設值。The default value is returned if the element does not provide one.

bool isContent = (bool)
   autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty);
Dim isContent As Boolean = CBool(autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty))

下列範例會抓取屬性目前的值,但指定如果專案本身未提供屬性的值, NotSupported 則會傳回而不是預設值。The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupported is to be returned instead of a default value.

bool isContent1;
object isContentNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty, true);
if (isContentNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    isContent1 = (bool)isContentNoDefault;
}
Dim isContent1 As Boolean
Dim isContentNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty, True)
If isContentNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    isContent1 = CBool(isContentNoDefault)
End If
