如何在没有消息泵送的情况下等待 WaitHandle?

问题描述

我想在 .NET 中调用 WaitHandle.WaitOne(TimeSpan)，但我在 STA 线程上，它在等待时会发送消息.由于超出此问题范围的原因，我需要等待不抽水.如何在不发送消息的情况下等待 WaitHandle 发出信号?

I want to call WaitHandle.WaitOne(TimeSpan) in .NET, but I'm on the STA thread and it pumps messages while waiting. For reasons that are beyond the scope of this question, I need to wait without pumping. How can I wait for a WaitHandle to be signaled without pumping messages?

在某些情况下，WaitHandle.WaitOne 似乎不会发送消息.但有时它确实适用于某些消息.有关更多信息，请参阅以下链接:

It seems in some scenarios that WaitHandle.WaitOne does not pump messages. But it does sometimes for some messages. See these links for more information on that:

1. Microsoft Windows 中的托管和非托管线程
2. 托管屏蔽

推荐答案

WaitForSingleObject 或 WaitForMultipleObjects 是非抽水等待；使用 p/invoke.

WaitForSingleObject or WaitForMultipleObjects are non-pumping waits; use p/invoke.

[DllImport("kernel32", SetLastError=true, ExactSpelling=true)]
public static extern Int32 WaitForSingleObject(SafeWaitHandle handle, Int32 milliseconds);
