This is similar to Clear(DSWriteOption, DataSourceClearedCallback) except that the operation is performed asynchronously. A CacheCleared event is fired upon successful completion of this method.It is not possible to determine if the actual operation has failed, therefore use this operation for the cases when it does not matter much.

Note: If exceptions are enabled through the ExceptionsEnabled setting, this property throws exception incase of failure.

A delegate that, that can be used to get the result of the Asynchronous Clear operation.Options regarding updating data source

The following example demonstrates how to clear the Cache.

CopyC#

void OnAsyncCacheCleared(object result)
{
...
}

NCache.Cache.ClearAsync(new AsyncCacheClearedCallback(OnAsyncCacheCleared));

Or simply in a class deriving from [!:Alachisoft.NCache.Web.UI.NPage] or [!:Alachisoft.NCache.Web.UI.NUserControl].

CopyC#

Cache.ClearAsync(new AsyncCacheClearedCallback(OnAsyncCacheCleared));
