DataCache.Unlock Method (String, DataCacheLockHandle, String)

[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]

Releases objects locked in the specified region. This method supports pessimistic concurrency by making sure that the appropriate DataCacheLockHandle is used for unlocking the object.

Namespace: Microsoft.Data.Caching
Assembly: ClientLibrary (in clientlibrary.dll)

Syntax

'Declaration
Public Sub Unlock ( _
    key As String, _
    lockHandle As DataCacheLockHandle, _
    region As String _
)
'Usage
Dim instance As DataCache
Dim key As String
Dim lockHandle As DataCacheLockHandle
Dim region As String

instance.Unlock(key, lockHandle, region)

public void Unlock (
    string key,
    DataCacheLockHandle lockHandle,
    string region
)

public:
void Unlock (
    String^ key, 
    DataCacheLockHandle^ lockHandle, 
    String^ region
)

public void Unlock (
    String key, 
    DataCacheLockHandle lockHandle, 
    String region
)

public function Unlock (
    key : String, 
    lockHandle : DataCacheLockHandle, 
    region : String
)

Parameters

• key
  The unique value that is used to identify the object in the region.

• lockHandle
  The DataCacheLockHandle object that was returned when the object was locked.

• region
  The name of the region where the object resides.

Remarks

The lockHandle parameter is required and must match the DataCacheLockHandle of the locked object to succeed. For more information about concurrency, see Concurrency Models (Velocity) and Concurrency Methods (Velocity).

Locked objects are never expired, but they may expire immediately if unlocked after their expiration time. For more information, see Expiration and Eviction (Velocity).
