用Socket实现的简单客户端和服务端程序（二）

 在“用Socket实现的简单客户端和服务端程序（一）“的基础上

本实例是把Socket的收发用一个程序来实现的下面的是代码

 

 

SocketAppWinForm.Desinger.cs的代码如下

namespace SocketAppWinForm { partial class Form1 { /// <summary> /// 必需的设计器变量。 /// </summary> private System.ComponentModel.IContainer components = null; /// <summary> /// 清理所有正在使用的资源。 /// </summary> /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose();

主要的逻辑控制在SocketAppWinForm.cs文件

本程序是在Windows 7 下用visusal stdio 2008调试通过。
