StreamWriter 在给定大消息时自动刷新缓冲区 [英] StreamWriter automatically flushing buffer when given large messages

问题描述

概述

我有一个客户端-服务器，其中我有 streamWriter.WriteLine(messageToClient); 在服务器上发送大消息.客户端上的 streamReader.ReadLine(); 正在读取 2000 条长度的消息.

I have a Client-Server whereby I have the streamWriter.WriteLine(messageToClient);on the server sending large messages. The streamReader.ReadLine(); on the client is reading the 2000 length messages fine.

这里的问题是 streamWriter.Flush() 对较大的消息没有影响，因为我的目标是服务器能够在直接刷新的缓冲区之间切换(具有流体服务器消息输出)而不是(服务器响应将被混合在一起，直到达到缓冲区限制以刷新).

The issue here is the streamWriter.Flush() has no affect on the larger messages, because what I am aiming for is the server to be able to switch between the buffers flushing directly (having a fluid server message output) and not (the server response would be jumbled together until it reaches the buffers limit to flush).

问题:我认为缓冲区已满会自动刷新?那么streamWriters 的最大缓冲区大小是多少?

Question: I am thinking that the buffers are auto flushing because they are full? Is so what is the streamWriters max buffer size?

我已经使用更小的 messageToClient 进行了测试，并且没有按预期刷新流.也就是服务器流一次向客户端输出一组小消息，大概是因为缓冲区已满.

I have tested using much smaller messageToClient and the not flushing of the stream works as intended. Aka the server stream outputs a group of small messages at once to the client, presumably because the buffer was full.

推荐答案

您是否尝试过使用 构造函数将缓冲区大小作为参数?

public StreamWriter(
    Stream stream,
    Encoding encoding,
    int bufferSize
)

编辑:在反射器中寻找默认缓冲区大小为 1024 字节.

Edit: poking around in reflector it looks like the default buffer size is 1024 bytes.
