AutomationElement.IsContentElementProperty 欄位


識別 IsContentElement 屬性。Identifies the IsContentElement property.

public: static initonly System::Windows::Automation::AutomationProperty ^ IsContentElementProperty;
public static readonly System.Windows.Automation.AutomationProperty IsContentElementProperty;
 staticval mutable IsContentElementProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly IsContentElementProperty As AutomationProperty 




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)
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.
    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.
    isContent1 = CBool(isContentNoDefault)
End If
