从多个线程异步写入文件 c# [英] Write to a file from multiple threads asynchronously c#

问题描述

这是我的情况.我希望在我的应用程序中尽可能高效地写入文件系统.该应用程序是多线程的，每个线程都可能写入同一个文件.有没有一种方法可以让我从每个线程异步写入文件，而不会让不同线程中的写入一起发生，可以这么说?

Here is my situation. I would like to make writing to the file system as efficient as possible in my application. The app is multi-threaded and each thread can possibly write to the same file. Is there a way that I can write to the file asynchronously from each thread without having the writes in the different threads bang heads together, so to speak?

我使用的是 C# 和 .NET 3.5，而且我也安装了 Reactive Extensions.

I'm using C# and .NET 3.5, and I do have the Reactive Extensions installed as well.

推荐答案

看看 异步 I/O.这将释放 CPU 以继续执行其他任务.
结合 ReaderWriterLock 作为@Jack BNimble 提到

Have a look at Asynchronous I/O. This will free up the cpu to continue with other tasks.
Combine with ReaderWriterLock as @Jack B Nimble mentioned

写入文件系统为尽可能高效

writing to the file system as efficient as possible

您的意思是使实际的文件 I/O 尽可能快，您将很难加快速度，磁盘只是在物理上变慢了.也许是SSD?

you mean making the actual file I/O as fast as possible you are going to have a hard time speeding it up much, disk is just physically slower. Maybe SSD's?
