C# UDP 文件传输实例源码

又是一个文件传输的一个程序，自己学习编程写的。(Is a file transfer of a program, written in their own learning programming.)

计算机网络选择重传协议，效率达到90 以上，北邮计科计算机网络课程作业(Select the computer network retransmission agreement, more than 90 efficiency, BUPT Jike computer network course work)

采用syn的扫描方式对一个网段的ip进行扫描，图形界面(Syn scan mode using a segment of ip scanning, graphical interface)

在多跳无线网络进行TDMA方式接入时候，时间是被划分为互不重叠的时隙，边长或定长帧在时隙中进行传输。 当面向节点时候，一个节点可以得到一个或者多个时隙，节点可以利用这些时隙向任何一条链路发送报文到邻居节点。 面向链路分配时候，则是某条单向链路分得一个或多个时隙，在这些时隙中，报文发送是单向的。(Time is divided into non-overlapping slots when multi-hop wireless networks are accessed by TDMA mode. Side-length or fixed-length frames are transmitted in slots. When facing a node, a node can get one or more slots, which can be used by the node to send messages to any link to its neighbors. For link allocation, a one-way link is allocated one or more slots, in which message transmission is one-way.)

部分win7/win8用户 运行时报错 可能是 权限问题,所以运行项目的时候 要右键>>以管理员身份运行 部分用户 运行该项目的时候 可能提示：协定需要双工 但是绑定 NetTcpBinding 不支持 这是只需要将host项目app.config中协议部分 改为wsDualHttpBinding 即可，如下代码： 另外使用wcf时，最好不要使用 using 因为使用using会屏蔽掉很多错误，误导用户，参考链接：http://www.codeproject.com/Tips/197531/Do-not-use-using-for-WCF-Clients 相关代码改为：using System;using System.Collections.Generic;using System.Linq;using System.Windows.Forms;using System.ServiceModel;namespace WcfUploadServiceHost{ static class Program { /// /// The main entry point for the application. /// [STAThread] static void Main() { try { var host = new ServiceHost(typeof (WcfUploadServiceLib.UpLoadService)); host.Open(); Console.WriteLine("Server is opened..."); Console.Read(); //using (var host = new ServiceHost(typeof(WcfUploadServiceLib.UpLoadService))) //{ // host.Open(); // Console.WriteLine("Server is opened..."); // Console.Read(); //} } catch (Exception ex) { Console.WriteLine(ex.ToString()); Console.Read(); } } }}

说明：  网络视频直播软件，基于QT5.7开发，使用tcp进行文字传输，udp进行视频传输(Network video live broadcast software, developed based on QT5.7, using TCP for text transmission and UDP for video transmission)
