如何将写入流1的内容传输到流2中? [英] How to pipe what is written to Stream 1 into Stream 2?

问题描述

这是我的情况:

producer.WriteStream(stream);
consumer.ReadStream(stream);

我想要一些东西，它允许将 producer 生成的字节逐步转移到 consumer .

I want something that allows the bytes generated by the producer to be progressively transfered to the consumer.

我可以将所有内容写入 MemoryStream ，然后倒带并在 consumer 上读取，但这会导致大量的内存消耗.

I could write everything to a MemoryStream, then rewind it and read it on the consumer, but that is causing huge memory consumption.

我该如何实现?

推荐答案

使用管道作为数据的基础传输，您可以拥有写入流"(服务器)和读取流"(客户端)，以实现以下目的:这样的沟通机制.

Using pipes as the underlying transport for your data, you can have a "write stream" (server) and a "read stream" (client) that allow for such communication mechanism.

使用匿名管道或命名管道(如果需要进程间通信)，都非常简单.要创建管道流，请执行以下操作:

It quite simple to do, either with anonymous pipes or named pipes (if you need inter-proc communication). To create your the pipe streams:

AnonymousPipeServerStream pipeServer = new AnonymousPipeServerStream();
AnonymousPipeClientStream pipeClient =
  new AnonymousPipeClientStream(pipeServer.GetClientHandleAsString());

现在您可以将其用作&阅读:

Now you can use these as to write & read:

producer.WriteStream(pipeServer);
// somewhere else...
consumer.ReadStream(pipeClient);
