Syntax
C# |
---|
public delegate void AsyncCacheClearedCallback( Object result ) |

---|
Public Delegate Sub AsyncCacheClearedCallback ( _ result As Object _ ) |
Visual C++ |

public delegate void AsyncCacheClearedCallback( Object^ result ) |
Parameters
- result
- Type: System..::..Object
The result of the asynchronous operation. If the operation completes successfully, it contains Success otherwise it contains an OperationFailedException indicating the cause of the operation failure.
Remarks
Since this handler is invoked every time an item is removed from the Cache, doing a lot
of processing inside the handler might have an impact on the performance of the cache and cluster. It
is therefore advisable to do minimal processing inside the handler.
Examples
The following example demonstrates how to use the AsyncCacheClearedCallback class to notifiy
an application when application's Cache object is cleared asynchronously. You could include this
code in a code declaration block in the Web Forms page, or in a page code-behind file.
CopyC#
public void OnAsyncCacheCleared(object result) { // ... } protected void Application_Start(object sender, EventArgs e) { try { NCache.InitializeCache("myCache"); NCache.Cache.ClearAsync(new AsyncCacheClearedCallback(OnAsyncCacheCleared)); } catch(Exception e) { } }
