StreamFrame
通用 socket 通讯框架：把"帧边界判定"与"帧内数据编解码"插件化，适用于通过 socket 进行数据互换的场景（设备通讯、物流 WMS 对接等）。把场景间的共性（连接管理、重连、读写、粘包/半包、消息分发）收敛到框架核心，把差异性（framing、codec）抽象成可插拔的驱动。
为什么用它
| 传统手写 | StreamFrame | |
|---|---|---|
| 接一种新设备/协议 | 重写连接、切帧、编解码 | 只写一个 ICodec<T> 驱动 |
| 帧边界（长度前缀 / STX-ETX / 自定义） | 各写各的 | 内置两种 + 可插拔 |
| 粘包/半包 | 手写缓冲拼接 | Pipelines 自动处理 |
| 重连 / 状态机 | 手写 | 内置自动重连 |
| 发送性能 | 多次拷贝 | 可选流式零拷贝 |
安装
dotnet add package StreamFrame
XML 报文驱动（可选）：
dotnet add package StreamFrame.Protocols.Xml
快速上手
一条连接 = 一个帧定界策略（framing）+ 一个编解码器（codec）+ 地址/端口/模式。framing 与 codec 均连接级固定，一条连接只流通一种消息类型、一种帧格式。
using System.Net;
using System.Xml.Linq;
using StreamFrame;
using StreamFrame.Abstractions;
using StreamFrame.Protocols.Xml;
// 服务端（被动监听）
var server = new StreamConnection<XDocument>(
new LengthPrefixFrameCodec(), // 4 字节大端长度头；也可用 StxEtxFrameCodec
new XmlDocumentCodec(), // 换成自己的 ICodec<T> 即可支持自定义协议
IPAddress.Any, 5100, isActive: false);
server.Start(ct);
await foreach (var doc in server.GetMessages(ct))
{
var id = doc.Root?.Element("Id")?.Value;
await server.SendAsync(XDocument.Parse($"<Reply><Echo>{id}</Echo></Reply>"), ct);
}
// 客户端（主动连接）
var client = new StreamConnection<XDocument>(
new LengthPrefixFrameCodec(),
new XmlDocumentCodec(),
IPAddress.Parse("127.0.0.1"), 5100, isActive: true);
client.Start(ct);
await client.SendAsync(XDocument.Parse("<Message><Id>1</Id></Message>"), ct);
概念
帧定界（IFrameCodec）— 怎么从字节流里切出一帧
| 实现 | 定界方式 | 适用 |
|---|---|---|
LengthPrefixFrameCodec |
4 字节大端长度头 + 负载 | 通用，二进制安全 |
StxEtxFrameCodec |
STX 0x02 … ETX 0x03 包裹 |
XML / 纯文本等已知安全的负载 |
两种默认实现都支持流式单缓冲编码（可选，消除发送侧 memcpy）。想自定义帧格式时实现 IFrameCodec 即可。
编解码（ICodec<T>）— 怎么解析/写入帧内数据
public interface ICodec<TMessage>
{
TMessage Decode(in ReadOnlySequence<byte> frame, CancellationToken ct = default);
void Encode(TMessage message, IBufferWriter<byte> writer, CancellationToken ct = default);
}
接新设备 = 写一个驱动：实现 ICodec<TMessage> + 定义业务消息类，选一个帧策略，其余全部复用。官方示例见 StreamFrame.Protocols.Xml。
连接（IStreamConnection<T>）— 传输层
- 客户端/服务端双模式：
isActive: true主动连远端，false被动监听 - 自动重连：
Connecting → Connected → Retry状态机 - 事件：
ConnectionChanged状态变化、RawBytesReceived/Sent原始字节（HEX 调试） - 发送背压：有界发送队列，队列满时
SendAsync自动等待
