HttpApplicationState.UnLock Method

Definition

Namespace:

System.Web

Assembly:

System.Web.dll

Unlocks access to an HttpApplicationState variable to facilitate access synchronization.

public:
 void UnLock();

public void UnLock ();

member this.UnLock : unit -> unit

Public Sub UnLock ()

Examples

The following example uses the Lock method and UnLock method to prevent other sessions from changing the value of two application variables until after the local session has changed them.

Application.Lock();
Application["MyCode"] = 21;
Application["MyCount"] = Convert.ToInt32(Application["MyCount"]) + 1;
Application.UnLock();

Application.Lock()
Application("MyCode") = 21
Application("MyCount") = Convert.ToInt32(Application("MyCount")) + 1
Application.UnLock()

Remarks

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.
