Przykłady

Poniższy przykład pokazuje, jak używać LockAttributes właściwości.The following example shows how to use the LockAttributes property.

// Show how to use LockAttributes.
// It locks and unlocks all the urls elements.
static void LockAttributes()
{

    try
    {
        // Get the current configuration file.

Uwagi

LockAttributesWłaściwość umożliwia zablokowanie wszystkich określonych atrybutów.The LockAttributes property allows you to lock all the attributes you specify.

W tym celu należy użyć Contains metody, zgodnie z opisem w sekcji przykład.To do that you use the Contains method, as explained in the Example section.

Uwaga

LockAttributesWłaściwość pozwala zapobiec modyfikowaniu podrzędnych elementów konfiguracji elementu, do którego ma zostać zastosowana reguła.The LockAttributes property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. Użyj, LockItem Jeśli chcesz umieścić ogólną blokadę elementu i jego elementów podrzędnych.Use LockItem if you want to put a general lock on the element itself and its child elements.

Uwagi dotyczące dziedziczenia

Jeśli używasz LockAllAttributesExcept LockAttributes właściwości i w tym samym czasie, ma zastosowanie najbardziej restrykcyjna reguła.If you use the LockAllAttributesExcept and LockAttributes properties at the same time, the most restrictive rule applies.
