.net - 多参数线程效率

Question

是否有更优雅的方式来编写以下语法？

        Thread t0 = new Thread(new ParameterizedThreadStart(doWork));
        t0.Start('someVal');
        t0.Join();

        Thread t1 = new Thread(new ParameterizedThreadStart(doWork));
        t1.Start('someDiffVal');
        t1.Join();

假设我们要传递 20 个不同的值，最好的设置方法是什么？循环并在最后加入？

如果一个新线程没有被实例化(如下所示)，它会报错说线程不能被重新启动。例如:

        Thread t1 = new Thread(new ParameterizedThreadStart(doWork));
        t1.Start('someVal');
        t1.Start('someDiffVal');

为什么要启动一个线程然后立即加入它？

我通常会这样做:

List<Thread> threads = new List<Thread>();

foreach (string item in items)
{
    string copy = item; // Important due to variable capture
    ThreadStart ts = () => DoWork(copy); // Strongly typed :)
    Thread t = new Thread(ts);
    t.Start();
    threads.Add(t);
}

foreach (Thread t in threads)
{
    t.Join();
}
