ConfigurationElement.LockAllElementsExcept Property

Gets the collection of locked elements.

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

Public ReadOnly Property LockAllElementsExcept As ConfigurationLockCollection

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


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

The following example shows how to use the LockAllElementsExcept property.

    ' Show how to use LockAllElementsExcept.
    ' It locks and unlocks all the MyUrls elements 
    ' except urls.
    Shared Sub LockAllElementsExcept()

            ' Get the current configuration file.
            Dim config _
            As System.Configuration.Configuration = _
            ConfigurationManager.OpenExeConfiguration( _

            ' Get the MyUrls section.
            Dim myUrlsSection As UrlsSection = _

            If myUrlsSection Is Nothing Then
                Console.WriteLine("Failed to load UrlsSection.")

                ' Get MyUrls section LockElements collection.
                Dim lockElementsExcept _
                As ConfigurationLockCollection = _

                ' Get MyUrls section LockElements collection 
                ' enumerator.
                Dim lockElementEnum As IEnumerator = _

                ' Position the collection index.

                If lockElementsExcept.Contains("urls") Then
                    ' Remove the lock on all the ther elements.
                    ' Add the lock on all the other elements 
                    ' but urls element.
                End If

            End If
        Catch err As ConfigurationErrorsException
            Console.WriteLine("[LockAllElementsExcept: {0}]", _
        End Try

    End Sub 'LockAllElementsExcept
