一、实现
1、数据库NewsDatabase
（1）数据表NewsInfo
CREATE TABLE [dbo].[NewsInfo] (
[NewsID] INT IDENTITY (1, 1) NOT NULL,
[NewsTitle] NVARCHAR (500) NULL,
[NewsData] NVARCHAR (1000) NULL,
[NewsDate] DATETIME NULL,
[NewsImageUrl] NVARCHAR (50) NULL,
[NewsCategory] NVARCHAR (20) NULL,
PRIMARY KEY CLUSTERED ([NewsID] ASC)
);（2）数据表Newsuser
CREATE TABLE [dbo].[Newsuser] (
[UserID] NVARCHAR (50) NOT NULL,
[UserPassword] NVARCHAR (50) NULL,
[UserName] NVARCHAR (50) NULL,
PRIMARY KEY CLUSTERED ([UserID] ASC)
);2、数据库配置代码
放在Web.config下
<connectionStrings>
<add name="NewsConnectionString"
connectionString="Data Source=(LocalDB)\MSSQLLocalDB; AttachDbFilename=|DataDirectory|\NewsDatabase.mdf; Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>3、css初始化文件Normalize.css

}总结
通过该网站的制作，我对ASP.NET有了更深层次的了解，也有了一些兴趣。同时我也对之前学习的html、css等前端开发技术在网页制作的过程与一些技巧手法有了加以深入的理解，对网页制作的一些常用手法也更加地熟练。
在具体的制作的过程中我认为一个网页的设计应该具备以下一些条件：
①确定网页设计的内容
一个网站要有一个明确的主题，整个网站围绕这个主题，在网页设计之前要明确网站有什么目的，是用来做什么，所有页面都是围绕着这个内容来制作，有了明确的内容就可以对网页进行一些前期的排版设计。
②做一个用户
在制作网页的过程中应该以用户身份亲身体验网站的各种功能才能真正地去发现问题和解决问题，才知道哪些地方需要加以改进，尽量不要让用户去发现问题，在前期设计时就应该把这些问题解决。
③优化内容
内容是整个网站的核心。在网站设计之前必须明确网站的内容安排。在具体的规划一个网站时，可以用树状结构先把每个页面的内容大纲列出来，尤其要制作一个大的网站(的时候，特别需要把这个架构规划好，也要考虑到以后可能的扩充性，免得做好以后又要一改再改整个网站的架构，免得浪费时间和精力。
