导读ASP.NET实现电影票信息的增删查改功能:题目 1、使用Code First技术创建一个Movie数据模型。 public class Movie { public int ID { get; set; } //电影编号 public string Title { get; set; } //电影名称 public DateTime ReleaseDate { get; set

题目

1、使用Code First技术创建一个Movie数据模型。

public class Movie
 {
 public int ID { get; set; } //电影编号
 public string Title { get; set; } //电影名称
 public DateTime ReleaseDate { get; set; } //上映时间
 public string Genre { get; set; } //电影类型
 public decimal Price { get; set; } //电影票价
 public string Rating { get; set; } //电影分级
 }

2、使用MVC相关技术实现数据的列表显示和新增功能。

3、完成数据的编辑、删除、明细和条件查询等功能。

4、完成如下查询：

（1）查询尚未上映电影的信息

（4）查询票价在某个区间的电影信息

效果

（源码在文章结尾）

主要涉及知识点

1、ASP.NET WEB MVC下的目录结构以及基础编程

2、Linq查询操作

3、Code First

4、各模板View的建立和使用

主要代码
