C＃ParameterizedThread从foreach中下一个对象的动作开始

Question

我在C＃中遇到了多线程问题。我通过foreach字典对象开始线程。

问题是插件对象在ParameterizedThread启动之前被下一个字典对象覆盖。

我如何不使用Thread.Sleep（10）之类的东西或等待ThreadState更改为“正在运行”而解决此问题？

_pluginWorkers = new Dictionary<string, Action<DateTime, DateTime>>();

... Filling _pluginWorkers with objects ...

foreach (var plugin in _pluginWorkers)
{
    var pluginAction = new ParameterizedThreadStart(obj => plugin.Value(timestart, timeend));
    Thread actionThread = new Thread(pluginAction, 1024 * 1024);
    actionThread.Start();
}
