プロパティ値

LockElements プロパティを使用する方法を次の例に示します。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());
    }
}

注釈

LockElementsプロパティを使用すると、指定したすべての要素をロックできます。The LockElements property allows you to lock all the elements you specify.

これを行うには、次Containsの例で説明するように、メソッドを使用します。To do that, you use the Contains method, as explained in the next example.

注意

LockElementsプロパティを使用すると、ルールを適用する要素の子構成要素が変更されないようにすることができます。The LockElements property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. 要素LockItem自体とその子要素に対して一般的なロックを設定する場合は、を使用します。Use LockItem if you want to put a general lock on the element itself and its child elements.
