TailPinnedEventArgs

範例

這個範例展示了如何利用事件 TailPinned 釋放對數序列中的空間。

recordSequence.RetryAppend = true;  
recordSequence.TailPinned += new EventHandler<TailPinnedEventArgs>(HandleTailPinned);  

void HandleTailPinned(object sender, TailPinnedEventArgs tailPinnedEventArgs)  
{  
   // tailPinnedEventArgs.TargetSequenceNumber is the target   
   // sequence number to free up space to.    
   // However, this sequence number is not necessarily valid.  We have  
   // to use this sequence number as a starting point for finding a  
   // valid point within the log to advance toward. You need to  
   // identify a record with a sequence number equal to, or greater  
   // than TargetSequenceNumber; let's call this   
   // realTargetSequenceNumber. Once found, move the base  

   recordSequence.AdvanceBaseSequenceNumber(realTargetSequenceNumber);  

}  

備註

TailPinned當記錄序列空間耗盡時，該事件可被觸發。 當此事件觸發時，序列的尾端（即基序號）會向前移動以釋放空間。
