我有一个使用单例类的Windows服务ThreadQueue<T>.当服务启动时,它会调用ThreadQueue<string>.Start()此类,然后接受并将限制并发性的任务排队到可配置数量的线程.
ThreadQueue<string>.Start() 在服务启动时调用一次且仅调用一次.
有时,在运行几个小时后,我收到以下异常:
Application: myservice.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NullReferenceException
Stack:

System.__Canon将此调用作为类型参数传递给它的是什么和什么？
谁能摆脱任何光明？
