简单的生产者,消费者同步控制,通过Event进行同步读写控制
public class DataObject
    {
        public long IntValue { get; set; }
        public string StrValue { get; set; }
    }    class Program
    {
        static AutoResetEvent writeEvent = new AutoResetEvent(true);
        static AutoResetEvent readEvent = new AutoResetEvent(false);        static DataObject dataObject = new DataObject();
        static void Main()
        {
            //Write Thread
            ThreadPool.QueueUserWorkItem(status =>
                {
                    while (true)
                    {
                        if (writeEvent.WaitOne(1))
                        {
                            dataObject.IntValue = DateTime.Now.Ticks;
                            dataObject.StrValue = Guid.NewGuid().ToString();
                            Console.WriteLine("Write:{0},{1}", dataObject.IntValue, dataObject.StrValue);
                            readEvent.Set();
                        }
                    }
                }, null);
            //Read Thread
            ThreadPool.QueueUserWorkItem(status =>
            {
                while (true)
                {
                    if (readEvent.WaitOne(1))
                    {
                        Console.WriteLine("Read:{0},{1}", dataObject.IntValue, dataObject.StrValue);
                        writeEvent.Set();
                    }
                }
            }, null);            Console.Read();
        }
    }
你也可以使用系统提供的ReaderWriterLock类去实现类似的功能
