原版本升级，更稳定功能更强 感谢网友对Beta的意见反馈 一、 使用G-TcpClient模块 二、 可以设定间隔时间发起大规模长、短连接 三、 可以发起密集数据包，包括即时和定时发送 四、 数据发送工作由一个独立线程担当，连接发起工作可设置多个独立的线程担当。 五、 可以多种模式组合连接或发送数据。

Unity scoket 通信 包含TCPClient客户端 项目和TCPServer 服务端 项目亲测好用 优质资源！ 两个项目都启动修改IP进行监听，通信。

本项目是Qt下，使用Tcp协议通讯的例子，使用的类主要是QTcpSocket和QTcpServer。好多博客中，有一个很大的误区，就是发送完数据之后，立即调用Socket.disconnectfromHost()，造成数据无法正常的被对方接收到，因此，应当等待关于这个Socket的所有操作完成之后，才能调用Socket.disConnectFromHost()函数

VB.NET的TCP协议通信工具，包括服务端TCPServer和客户端TCPClient

服务器可以接收多个客户端发送的消息，并显示消息来源。 服务器可以发送消息到指定客户端 客户端可以自动连接服务器，断连后重连 客户端可以发送消息到服务器，可接收服务器消息 类似框架可以用做中央服务器及客户端项目
