Gets the collection of locked elements.

Namespace:   System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

Syntax
public ConfigurationLockCollection LockAllElementsExcept { get; }
public:
property ConfigurationLockCollection^ LockAllElementsExcept {
	ConfigurationLockCollection^ get();
}
member LockAllElementsExcept : ConfigurationLockCollection with get
Public ReadOnly Property LockAllElementsExcept As ConfigurationLockCollection

Property Value

Type:

The ConfigurationLockCollection of locked elements.

Remarks

The property allows you to lock all the elements at once, except for the one you specify.

System_CAPS_noteNote

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

Examples

The following example shows how to use the property.

// Show how to use LockAllElementsExcept.
// It locks and unlocks all the MyUrls elements 
// except urls.
static void LockAllElementsExcept()
{

    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 lockElementsExcept =
                myUrlsSection.LockAllElementsExcept;

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

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

            if (lockElementsExcept.Contains("urls"))
                // Remove the lock on all the ther elements.
                lockElementsExcept.Remove("urls");
            else

                // but urls element.
                lockElementsExcept.Add("urls");
