我在创建连续计时器时遇到了麻烦.在计时器上创建了多个交错的线程,这些线程将运行一段时间然后完全停止.我允许的最大线程数为5,定时器间隔设置为10000.因此理论上每2秒执行1个线程.
这种情况会发生一段时间,但随后会停止.目前我正在测试控制台应用程序并将响应写入应用程序.
我不确定这里发生了什么
internal class EngineThreadGenerator
{
private readonly AutoResetEvent _autoEvent;
private readonly Action<string, string> _processQueueDelegate;
private readonly Action<string, string> _purgeQueueDelegate;
private void createAllowedEmailThreads()
{
for (int counter = 0; counter < AppSettings.ProcessQueueAllowedThreads; counter++)
{
EmailThread _emailThread = new EmailThread(_collection, _processQueueDelegate, _purgeQueueDelegate);
TimerCallback _timerCallback = _emailThread.InitEmailThread;
Timer _stateTimer = new Timer(_timerCallback, _autoEvent, 0, AppSettings.ProcessIntervalInMilliseconds);
pauseLoop();
}
}
