-------------------------------------------------------------------------------------从日志可以看出，ping成功的IP数越来越少，明显是不正常的

Answer 1

从日志可以看出，ping成功的IP数越来越少，明显是不正常的希望大侠们指教啊！不知道BUG究竟在哪里？

Answer 2

线程函数没有参数?
你这不论是开1000个线程还是10000个线程,都走的一样的逻辑,并没有各ping各的机器啊

Answer 3

而且已经写了while死循环了,又加timer,已经写了多线程了,又用.Set()同步,这是想干啥

Answer 4

．．．．没有把PIN的IP放到队列里呀汗

Answer 5

在：加载数据()，这个方法里面，把数据放到：private List<string> _需要扫描的IP = new List<string>();这里面了。在ping方法里面用了removeat(0)来移除已经ping过的IP了。
