ConfigurationElement.LockAllAttributesExcept Property

Gets the collection of locked attributes.

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

'Declaration
Public ReadOnly Property LockAllAttributesExcept As ConfigurationLockCollection

Property Value

Type: System.Configuration.ConfigurationLockCollection
The ConfigurationLockCollection of locked attributes (properties) for the element.

The LockAllAttributesExcept property allows you to lock all the attributes at once, with the exception of the one you specify. To do that, you use the Contains method, as explained in the Example section.

NoteNote

The LockAllAttributesExcept 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 parent element itself and its child elements.

Notes to Implementers

If you use the LockAllAttributesExcept and LockAttributes properties at the same time, the most restrictive rule applies.

The following example shows how to use the LockAllAttributesExcept.


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

        Try
            ' Get the current configuration file.
            Dim config _
            As System.Configuration.Configuration = _
            ConfigurationManager.OpenExeConfiguration( _
            ConfigurationUserLevel.None)

            ' Get the MyUrls section.
            Dim myUrlsSection As UrlsSection = _
            config.GetSection("MyUrls")

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

                Dim elemEnum As IEnumerator = _
                myUrlsSection.Urls.GetEnumerator()

                Dim i As Integer = 0
                While elemEnum.MoveNext()

                    ' Get current element.
                    Dim element _
                    As ConfigurationElement = _
                    myUrlsSection.Urls(i)

                    ' Get current element lock all attributes.
                    Dim lockAllAttributesExcept _
                    As ConfigurationLockCollection = _
                    element.LockAllAttributesExcept

                    ' Add or remove the lock on all attributes 
                    ' except port.
                    If lockAllAttributesExcept.Contains("port") Then
                        lockAllAttributesExcept.Remove("port")
                    Else
                        lockAllAttributesExcept.Add("port")
                    End If

                    Dim lockedAttributes As String = _
                    lockAllAttributesExcept.AttributeList()

                    Console.WriteLine("Element {0} Locked attributes list: {1}", _
                    i.ToString(), lockedAttributes)

                    i += 1

                    config.Save(ConfigurationSaveMode.Full)
                End While
            End If


        Catch e As ConfigurationErrorsException
            Console.WriteLine("[LockAllAttributesExcept: {0}]", _
            e.ToString())
        End Try

    End Sub 'LockAllAttributesExcept
