Thread.Sleep 方法 (Int32)
将当前线程挂起指定的时间。
命名空间:System.Threading
程序集:mscorlib（在 mscorlib.dll 中）
程序集:mscorlib（在 mscorlib.dll 中）
线程不会按操作系统的计划在指定的时段内执行。此方法更改线程的状态以包括 WaitSleepJoin。
此方法不执行标准的 COM 和 SendMessage 消息泵处理。
| 注意 |
|---|
| 如果需要在具有 STAThreadAttribute 的线程上休眠，但是不想执行标准的 COM 和 SendMessage 消息泵处理，则请考虑使用指定超时间隔的 Join 方法的一个重载。 |
下面的代码示例阐释了休眠的线程。
using System; using System.Threading; class ApartmentTest { static void Main() { Thread newThread = new Thread(new ThreadStart(ThreadMethod)); newThread.SetApartmentState(ApartmentState.MTA); // The following line is ignored since // ApartmentState can only be set once. newThread.SetApartmentState(ApartmentState.STA); Console.WriteLine("ThreadState: {0}, ApartmentState: {1}", newThread.ThreadState, newThread.ApartmentState); newThread.Start(); // Wait for newThread to start and go to sleep. Thread.Sleep(300); try { // This causes an exception since newThread is sleeping. newThread.SetApartmentState(ApartmentState.STA); } catch(ThreadStateException stateException) { Console.WriteLine("\n{0} caught:\n" + "Thread is not in the Unstarted or Running state.", stateException.GetType().Name); Console.WriteLine("ThreadState: {0}, ApartmentState: {1}", newThread.ThreadState, newThread.GetApartmentState()); } } static void ThreadMethod() { Thread.Sleep(1000); } }
