C＃中，有没有这样的事情作为"线程安全"流？ [英] C#, is there such a thing as a "thread-safe" stream?

问题描述

我重定向过程的输出到这是我后来读一个StreamReader。我的问题是我使用的应该有这样流单独实例多个线程。当我去阅读，穿线呓语道此流并开始执行奇怪。

是否有这样的事情是把一个线程安全的流
的编辑：我把门锁上ReadToEnd的上的StreamReader，并在那里我做了线：读卡器= proc.StandardOutput;

I am redirecting the output of a process into a streamreader which I read later. My problem is I am using multiple threads which SHOULD have separate instances of this stream. When I go to read this stream in, the threading fudges and starts executing oddly.

Is there such a thing as making a thread-safe stream?
I put locks on the ReadToEnd on the streamreader, and the line where I did: reader = proc.StandardOutput;

推荐答案

类你有内置的框架SyncrhonizedStream，他们只是不暴露看一下/子等，但可以使用

There's a SyncrhonizedStream built into the framework, they just don't expose the class for you to look at/subclass etc, but you can turn any stream into a SynchronizedStream using

var syncStream = Stream.Synchronized(inStream);

您应该围绕传递syncStream对象需要它的每个线程，并确保你从来没有尝试访问inStream中的代码的其他地方。

You should pass the syncStream object around to each thread that needs it, and make sure you never try to access inStream elsewhere in code.

SynchronizedStream只是所有的读/写操作实现了监控，以确保一个线程到流互斥访问。

The SynchronizedStream just implements a monitor on all read/write operation to ensure that a thread has mutually exclusive access to the stream.

编辑：

看来他们也实现了框架太一SynchronizedReader / SynchronizedWriter

Appears they also implements a SynchronizedReader/SynchronizedWriter in the framework too.

var reader = TextReader.Synchronized(process.StandardOutput);
