Beispiele

Im folgenden Beispiel wird die Verwendung der LockElements-Eigenschaft veranschaulicht.

// 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.");
        }

            // enumerator.
            IEnumerator lockElementEnum =
                 lockElements.GetEnumerator();

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

            if (lockElements.Contains("urls"))

Hinweise

Mit LockElements der -Eigenschaft können Sie alle von Ihnen angegebenen Elemente sperren.

Verwenden Sie dazu die Contains -Methode, wie im nächsten Beispiel erläutert.

Hinweis

Mit LockElements der -Eigenschaft können Sie verhindern, dass die untergeordneten Konfigurationselemente des Elements, auf das Sie die Regel anwenden, geändert werden. Verwenden Sie LockItem , wenn Sie eine allgemeine Sperre für das Element selbst und seine untergeordneten Elemente festlegen möchten.
