HttpApplicationState.UnLock Method

Unlocks access to an HttpApplicationState variable to facilitate access synchronization.

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

member UnLock : unit -> unit 

The HttpApplicationState class performs automatic locking and unlocking with the AllKeys and Count properties and the Add, Clear, Get, GetKey, Remove, RemoveAt and Set methods. However, explicitly using the Lock and UnLock methods when you have a series of operations may be more efficient.
