Beispiele

Im folgenden Beispiel wird die Verwendung der LockElements-Eigenschaft veranschaulicht.The following example shows how to use the LockElements property.

// Show how to use LockElements
// It locks and unlocks the urls element.
static void LockElements()
{

    try
    {
        // Get the configuration file.
        System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

        // Get the MyUrls section.
        UrlsSection myUrlsSection =
            config.GetSection("MyUrls") as UrlsSection;

        if (myUrlsSection == null)
            Console.WriteLine("Failed to load UrlsSection.");
        else
        {
            // Get MyUrls section LockElements collection.
            ConfigurationLockCollection lockElements =
                myUrlsSection.LockElements;

            // Get MyUrls section LockElements collection 
            // enumerator.
            IEnumerator lockElementEnum =
                 lockElements.GetEnumerator();

            // Position the collection index.
            lockElementEnum.MoveNext();

            if (lockElements.Contains("urls"))
                // Remove the lock on the urls element.
                lockElements.Remove("urls");
            else
                // Add the lock on the urls element.
                lockElements.Add("urls");

            // Save the change.
            config.Save(ConfigurationSaveMode.Full);

        }

    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine("[LockElements: {0}]",
            err.ToString());
    }
}

Hinweise

Mit der LockElements-Eigenschaft können Sie alle von Ihnen angegebenen Elemente sperren.The LockElements property allows you to lock all the elements you specify.

Zu diesem Zweck verwenden Sie die Contains-Methode, wie im nächsten Beispiel erläutert.To do that, you use the Contains method, as explained in the next example.

Hinweis

Mit der LockElements-Eigenschaft können Sie verhindern, dass die untergeordneten Konfigurationselemente des Elements, auf das die Regel angewendet wird, geändert werden.The LockElements property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. Verwenden Sie LockItem, wenn Sie eine allgemeine Sperre für das Element selbst und seine untergeordneten Elemente verwenden möchten.Use LockItem if you want to put a general lock on the element itself and its child elements.
