在.NET中并发线程之间传递数据的最佳方法是什么？

我有两个线程,一个需要轮询一堆独立的静态资源来寻找更新.另一个需要获取数据并将其存储在数据库中.线程1如何告诉线程2有什么要处理的？

如果数据片段是独立的,则将数据片段视为要由线程池处理的工作项.使用线程池并将QueueUserWorkItem数据发布到线程.您应该使用对称线程池来获得更好的可伸缩性,并限制生产者和消费者之间必须发生的同步量.

例如(来自MSDN):

    TaskInfo ti = new TaskInfo("This report displays the number {0}.", 42);

    // Queue the task and data.
    if (ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadProc), ti)) {    
        Console.WriteLine("Main thread does some work, then sleeps.");

        // If you comment out the Sleep, the main thread exits before
        // the ThreadPool task has a chance to run.  ThreadPool uses 
        // background threads, which do not keep the application 
        // running.  (This is a simple example of a race condition.)
        Thread.Sleep(1000);

        Console.WriteLine("Main thread exits.");
    }
    else {
        Console.WriteLine("Unable to queue ThreadPool request."); 
    }


// The thread procedure performs the independent task, in this case
// formatting and printing a very simple report.
//
static void ThreadProc(Object stateInfo) {
    TaskInfo ti = (TaskInfo) stateInfo;
    Console.WriteLine(ti.Boilerplate, ti.Value); 
}

我在工作项的队列上使用Monitor.Wait/Pulse.
