MSDN文档说Thread.Sleep()可以在可移植类库中使用。编译器另有说明。除了自旋环外,我还有哪些选择? Thread.CurrentThread.Join()也不存在。

最佳答案

这是“便携式”的不幸副作用。通过减法,库变得高度可移植,删除了许多可能的目标之一中不可用的所有部分。这对Thread类造成了严重破坏,它完全没有任何有用的成员。仅剩5个了,分别是MemoryBarrier(),CurrentCulture,CurrentThread,CurrentUICulture和ManagedThreadId。

这可能看起来很奇怪,广告目标的交叉点当然支持更多。这可能与未经广告的广告有关。 Windows 8即将发布的版本将在ARM内核上运行。取决于您使用的工具,也称为WinRT或Metro或“.NET for Metro风格的应用程序” API。 WinRT严重削减了传统的Windows API,它的System.Windows.Threading命名空间非常空。

这将对SO产生大量问题,例如“Eeek,现在我该怎么办”。此处可能的解决方法是烧毁一个虚拟的System.Threading.ManualResetEvent对象。它具有WaitOne(TimeSpan)方法。

Fwiw,我个人不希望针对该库进行编程。到目前为止,最令人担忧的花絮是在您提供的链接的“问答”部分中:



哎哟。便携,运动。这需要炖一会儿。我对DevDiv尤其是David Kean的同情是艰巨的工作。
