具有聊天功能的Blog实现 第一章 绪论
第一章 绪论
1.1 系统开发背景
随着计算机技术的发展和普及，blog得到了极大的发展。Blog，是Weblog的简称。blog是一种新的生活方式、新的工作方式、新的学习方式和交流方式。它是继E-mail、BBS、ICQ、之后出现的第4种网络交流方式。Blog主要应用于3个方面：一是新的人际交流方式；二是以个人为中心的信息摘选和知识管理；三是以个人为中心的传播出版。blog作为个人的一种学习工具，简单易用，吸引人的兴趣。Blog在教育方面得到了很大的发展，它将互联网从过去的通讯功能，资料功能、交流功能等进一步强化，使其更加个性化、开放化、实时化、全球化，把信息共享发展到资源共享、思想共享、生命历程共享。Blog已经成为一种继课件、积件、资源库、教育主题网站等信息化教学模式之后，新的网络应用模式。它是应时代的需求而兴起的，也是应时代需求不断进步的。
1.2课题研究的意义
随着Blog人数的增加，Blog作为一种新的生活方式、新的工作方式和新的学习方式已经被越来越多的人所接受，并且在改变传统的网络和社会结构。它使交流和沟通更有明确的选择和方向性；单一的思想和群体的智慧结合变得更加有效；个人出版变成人人都可以实现的梦想。Blog正在影响和改变着我们的生活。
Blog是以网络作为载体，简易迅速便捷地发布自己的心得，及时有效轻松地与他人进行交流，再集丰富多彩的个性化展示于一体的综合性平台。展示丰富的个性化，对Blog功能的要求自然更高，新一代具有更多、更新、更全功能的Blog急需走进舞台。系统加入聊天功能可以更加方便大家的交流。

具有聊天功能的Blog实现 第二章 Blog系统开发技术
第二章 Blog系统开发技术
2.1ASP.NET介绍
本系统采用ASP.NET开发技术进行开发。ASP.NET不仅仅是ASP的一个新版本，更是Web应用程序编程方面的一个全新的概念和方法。ASP.NET中的新功能并不是对ASP的改进，设计它的初衷是为用户入境提供最佳的应用程序架构。它相比于ASP有着以下几个方面的优点: （1） 多语言
ASP曾在脚本引擎方面受到了限制，特别是VBScript和Jscript。而ASP.NET则支持多种语言，默认情况下为Visual Basic.NET、C#和Jscript.NET，另外还支持一些第三方语言。 （2） 服务器处理
ASP在服务器处理上不管页面的内容是纯HTML还是ASP生成的HTML，它都是按照实现，形成所谓3-tier页面顺序显示的。因此逻辑代码依赖于它在页面中的位置，并且无法将HTML控件作为目标，除非将它们作为流的一部分进行显示。而ASP.NET就解决了这个问题，方法是为控件引入一个声明的基于服务器的模型，因为控件在服务器上有，可以在服务器上编程，也可以是客户端驱动的事件。
（3） Web Form控件
将现有的HTML控件转换为服务器端的控件是比较容易的，但是也存在一些不方便，例如比较难于区分HTML控件和服务器端的控件。于是Microsoft公司就创建了一组专门的服务器控件，它们都用asp：前缀标识。 （4） 代码与内容分离
一个网站的设计与开发往往由不同的人来实现的，而ASP中就是存在着这样一个问题，代码（ASP脚本）和内容（HTML）混合在一起。这样就使得同时进行设计和开发变得很困难。而ASP.NET则采用了代码内联和后台编码两种方法实现了代码与内容的分离。
