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.
Note
The LockElements property allows you to prevent the child configuration elements of the element to which you apply the rule from being modified. Use LockItem if you want to put a general lock on the element itself and its child elements.
