Examples

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());
    }
}

Remarks

The LockElements property allows you to lock all the elements you specify.

To do that, you use the Contains method, as explained in the next example.
