TouchSocket✓

TouchSocket是.Net(包括 C# 、VB.Net、F#)的一个整合性的socket网络通信框架。包含了 tcp、udp、ssl等一系列的通信模块。一键式解决 tcp 黏分包问题，udp大数据包分片组合问题等。使用协议模板，可快速实现「固定包头」、「固定长度」、「区间字符」等一系列的数据报文解析。 TouchSocket is Net (including C #, VB An integrated socket network communication framework based on Net and F #. It includes a series of communication modules such as TCP, UDP, SSL, etc. One click solution to TCP packet sticking and UDP packet fragmentation and combination problems. By using protocol templates, a series of data message parsing techniques such as "fixed packet header", "fixed length", and "interval characters" can be quickly implemented.

SocketMessaging

Event-driven wrappers around System.Net.Sockets.Socket, that support different message protocols ontop of raw communication.
