推荐答案

你不能让线程以与Windows不是实时操作系统相同的速度运行。



您可以做的最好的事情是通过设置ManualResetEvent来同步所有BackgroundWorkers的开头。每个Worker开始时的代码到达MRE并等待信号开始。一旦你启动了所有的BGW，那么下一个声明应该是在MRE上设置信号，释放BGW来完成其余的工作。



即便如此，你不会有一个完美的开始。您正在与Windows中运行的所有其他线程共享CPU核心！在Windows解决之前，部分或全部线程可能根本不运行。你无能为力。

You can't make the threads run at the same speed as Windows is not a real-time operating system.

The best you can do is to synchronize the start of all of the BackgroundWorkers by setting up a ManualResetEvent. The code at the start of each Worker gets to the MRE and waits for the signal to start. Once you start all of your BGW's, then next statement should be setting the signal on the MRE, releasing the BGW's to do the rest of their work.

Even then, you're not going to get a perfect start. You're sharing the CPU cores with all of the other threads running in Windows! Some or all of your threads may not be running at all until Windows gets around to it. There is nothing you can do about this.
