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
MovieController.cs
