ConfigurationElement.LockAllAttributesExcept Property

 

Gets the collection of locked attributes.

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

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.

System_CAPS_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.
