介绍开源的.net通信框架NetworkComms框架 源码分析（八）SharpZipLibGzipCompressor

原文网址： http://www.cnblogs.com/csdev

Networkcomms 是一款C# 语言编写的TCP/UDP通信框架  作者是英国人  以前是收费的 目前作者已经开源  许可是:Apache License v2

开源地址是:https://github.com/MarcFletcher/NetworkComms.Net

SharpZipLibGzipCompressor  是7Zip数据加密器

数据加密会加大Cpu负载，很多时候并不启用。
