在审查了这个论坛上的很多帖子以及其他关于c#multithreading的帖子后,我仍然感到困惑,并且在处理手头的问题时遇到了问题.
我想创建numThreads多个线程来为每个整数执行一个函数documentIds.documentIds是List<int>Count = 100,我想在其中的每个元素上调用RestitchWorker.Restitch documentIds.
我目前的情况如下,但我很困惑如何保持5个线程继续循环通过100个documentIds列表...所有帮助表示赞赏.

Thread t_restitchWorker = new Thread(() => Worker.Restitch());
threadCount++;
t_restitchWorker.Start();
t_restitchWorker.Join();
}
