public static void Main(string[] args) { //当前主线程命名槽位 var slot = Thread.AllocateDataSlot(); Thread.SetData(slot, "jack"); var t = new Thread(() => { //slot对其他线程是不可见的 var obj = Thread.GetData(slot); Console.WriteLine($"工作线程:{obj}");//无法打印内容 }); t.Start(); var obj2 = Thread.GetData(slot); Console.WriteLine($"主线程{obj2}");//打印jack Console.ReadKey(); }
类似上面的还有ThreadStatic
//ThreadStatic 指示每个静态类型字段对于每一个线程都是唯一的 [ThreadStatic] static string name = string.Empty; public static void Main(string[] args) { name = "jack"; var t = new Thread(() => { Console.WriteLine($"工作线程:{name}");//无法打印内容 }); t.Start(); Console.WriteLine($"主线程{name}");//打印jack Console.ReadKey(); }
ThreadLocal
public static void Main(string[] args) { ThreadLocal<string> local = new ThreadLocal<string>(); local.Value = "jack"; var t = new Thread(() => { Console.WriteLine($"工作线程:{local.Value}");//无法打印内容 }); t.Start(); Console.WriteLine($"主线程{local.Value}");//打印jack Console.ReadKey(); }
