为什么我的Thread.Interrupt无法正常工作?
执行中断操作的代码:
public void Stop()
{
const string LOG_SOURCE = "ProcessingDriver";
if (_Enabled)
{
try
{
RequestProcessor.Disable();
if (ProcessingThread != null)
{
ProcessingThread.Interrupt();
ProcessingThread.Join();
}
}
catch (Exception ex)
{
WriteLog(LOG_SOURCE, ex);
}
}
}
我希望停止的代码:
private void ProcessRequests()
{
const string LOG_SOURCE = "ProcessRequests";
try
{
ProcessingThread = Thread.CurrentThread;
while (!_Disposed)
{
_ProcessingWaitHandle.WaitOne();
int count = GetRequestCount();
while (count > 0)
{
try
{
ExportRequest er = GetRequest();
ProcessRequest(er);
}
catch (ThreadInterruptedException)
{
throw;
}
catch (Exception ex)
{
WriteLog(LOG_SOURCE,
ex);
WriteLog(LOG_SOURCE,
"Request Failed.");
}
//Suspend to catch interupt
Thread.Sleep(1);
count = GetRequestCount();
}
}
}
catch (ThreadInterruptedException)
{
WriteLog(LOG_SOURCE,
"Interupted. Exiting.", LogType.Info);
}
catch (Exception critEx)
{
//Should never get here
WriteLog(LOG_SOURCE, critEx);
WriteLog(LOG_SOURCE,
"Serious unhandled error. Please restart.", LogType.Critical);
}
}
我已经仔细阅读了代码。我可以看到Interrupt被调用了(此时Sleep或Wait不是活动命令),我也可以看到Sleep被调用,但是从来没有抛出Interrupt错误(即使线程在WaitOne上阻塞时也没有)。
我做错了什么?
