C#多线程并行编程--第三课

            ////分配已经命名的槽位
            //var solt=Thread.AllocateNamedDataSlot("username");
            //// var solt = Thread.AllocateDataSlot();
            ////在主线程中给槽位赋值，只能在主线程读取，子线程读取不到
            //Thread.SetData(solt, "Hello Word!");
            //var t = new Thread(()=> {

            //    var obj = Thread.GetData(solt);
            //    Console.WriteLine("当前工作的线程：{0}",obj);
            //});
            //t.Start();

            //var obj2= Thread.GetData(solt);
            //Console.WriteLine("主线程：{0}", obj2);
