socket传输图片的例子,delphi代码,在 Delphi XE 中测试通过,里面包含服务器端和客户端源代码.

软件名称：网络UDP调试工具 软件可以发送、接收UDP网络消息，同时支持客户端和服务器模式

Python网络开发必备参考书籍，TCP、UDP socket实现应有尽有。

这是用C#写的socket通信的源码，可以直接运行修改

利用Delphi编写Socket通信程序

C#里边要实现Socket网络编程，实现tcp和udp协议收发任意的数据，比如二进制的图片、音频、视频等数据，或者是xml,json，字符串等文本数据。我们可以采用.NET自带的类库编写，但是由于这些类库只是基础的设施，需要自行处理比如断线重连、网络波动、tcp粘包等等问题，并且还要考虑稳定性和吞吐等因素，所以可以调用一些类库。 这里介绍一个比较稳定可靠，又接口简单的sdk类库。名字叫SharpSocket。本源码是一个示例，教你如何使用该库快速创建稳定快速的网络通信项目

本例程有配套的安卓教程，本篇重点是socket长连接，zxing，listview在项目中有用到，在这里不讲了，关于zxing可以参考大神的：http://blog.csdn.net/xiaanming/article/details/10163203

基于VB.net的服务器端和客户端SOCKET通信例程，服务端启动侦听，客户端发送数据在服务器端即可收到。
