C#超大文件发送与接收代码
C#超大文件发送与接收代码。用于开发超大文件的发送与接收
C# TCP Socket 分包传送数据
C# TCP Socket 分包传送数据，这个代码也是从别的地方淘来的，用的还不错。
C#文件系统的操作
本课程将介绍如何在C#中执行读写文件操作，读写文件夹操作。
基于C# TCP文件传输
分别分为2部分 一部分是发送方 另外一部分是接收方 接收方是控制台模式实现的 节省了很多不必要的代码 默认文件存放地址为c:\ 根目录下 只能传输单个文件 不能传输文件夹 已经经过验证 电影等大资源也可正常传输
c#实现QQ聊天程序(源代码)(分服务端和客户端，采用tcp连接)(更新版)
采用tcp有连接编程，同步发送和异步接收 分为客户端和服务器端。 客户端的任务是发送消息给服务器 服务器的任务是接收客户端发来的消息进行判断，是操作数据库还是进行转发或者留言。 客户端也支持文件的传输。
