如何中断 IO 绑定线程

发布于 2024-09-30 04:51:59 字数 272 浏览 4 评论 0原文

我正在打开一个 System.Diagnostic.Process 来从进程中读取标准输出，并且我希望能够在经过一定时间后中断它。

try
{
    output = outputStream.ReadToEnd();
}
catch (ThreadInterruptedException e)
{
    return;
}

这是行不通的，因为线程位于 ReadToEnd() 方法中。我尝试从主线程关闭流，希望能够使 Read 方法结束，但这也不起作用。

I am opening a System.Diagnostic.Process to read the stdout from a process and I would like to be able to interrupt it after a certain elapsed time.

try
{
    output = outputStream.ReadToEnd();
}
catch (ThreadInterruptedException e)
{
    return;
}

That doesn't work since the thread is in the ReadToEnd() method. I attempted to close the stream from the main thread, hoping that'd EOF the Read method, but that didn't work either.

我会冒险中止

try 
{ 
    Timer watchdog = new Timer(abortMe, Thread.CurrentThread, timeout, Timeout.Infinite);
    output = outputStream.ReadToEnd(); 
    watchdog.Dispose();
} 
catch (ThreadAbortException e) 
{ 
    return; 
} 

private void abortMe(object state)
{
    ((Thread)state).Abort()
}

实际上，当我使用 TCP 和 UDP 套接字时，我成功地关闭了流：它触发了 SocketException 并且线程被成功中断。

顺便问一下，您的流应该是输入流吗？你不应该读取输出流......

I would hazard aborting

try 
{ 
    Timer watchdog = new Timer(abortMe, Thread.CurrentThread, timeout, Timeout.Infinite);
    output = outputStream.ReadToEnd(); 
    watchdog.Dispose();
} 
catch (ThreadAbortException e) 
{ 
    return; 
} 

private void abortMe(object state)
{
    ((Thread)state).Abort()
}

Actually I succeed in closing the stream when I work with TCP and UDP sockets: it triggers a SocketException and the thread gets successfully interrupted.

By the way, should your stream be an input stream? You're not supposed to read an output stream...
