国内c#网络编程方面的资料比较少，看看国外的吧。全书主要分三个部分：

网络层基础开发

网络层高级开发

应用层开发

总体而言书不错哦-domestic c # Network Programming the information is relatively small, look at it from abroad. The book is divided into three parts : network layer infrastructure and development of network-tier level development and application layer development on the whole pretty good! !
