摘要：即時(shí)通訊軟件是目前計(jì)算機(jī)用戶進(jìn)行交流最普遍的方式之一，它使人們的交流更加方便、快捷。本文分析了即時(shí)通訊系統(tǒng)的原理及其實(shí)現(xiàn)過(guò)程，探討了Socket技術(shù)在C/S模式下的局域網(wǎng)即時(shí)通訊系統(tǒng)的應(yīng)用。系統(tǒng)主要采用C/S架構(gòu)、C#編程語(yǔ)言、.NET開(kāi)發(fā)平臺(tái)、UDP通信協(xié)議以及Socket等技術(shù)來(lái)完成。主要實(shí)現(xiàn)的功能有注冊(cè)、登錄、聊天以及文件傳輸?shù)裙δ?。通過(guò)運(yùn)行、測(cè)試與分析，該多功能聊天軟件運(yùn)行穩(wěn)定、可靠，具有一定的實(shí)用價(jià)值。

The Design and Implementation of Instant Messaging Software
Abstract: Instant messaging software is one of the most common ways of computer users to communicate;
by using this software, the communication among people become more convenient and faster. This thesis analyzes the principle and the implementation of the instant messaging system; then discusses the application of Socket technology based on C/S structure instant messaging system in LAN. This system is designed and implemented by using C# programming language, .NET framework, UDP protocol, Socket and others techniques; it realized some useful functions such as register, login, chat, file transfer and so on. Through the operation, analysis and testing, the chat software operation is stable,reliable and has a certain practical value.
