ASP.NET實(shí)現(xiàn)電影票信息的增刪查改功能
題目
1、使用Code First技術(shù)創(chuàng)建一個(gè)Movie數(shù)據(jù)模型。
public class Movie
{
public int ID { get; set; } //電影編號(hào)
public string Title { get; set; } //電影名稱
public DateTime ReleaseDate { get; set; } //上映時(shí)間
public string Genre { get; set; } //電影類型
public decimal Price { get; set; } //電影票價(jià)
public string Rating { get; set; } //電影分級(jí)
}
2、使用MVC相關(guān)技術(shù)實(shí)現(xiàn)數(shù)據(jù)的列表顯示和新增功能。
3、完成數(shù)據(jù)的編輯、刪除、明細(xì)和條件查詢等功能。
4、完成如下查詢:
(1)查詢尚未上映電影的信息
(4)查詢票價(jià)在某個(gè)區(qū)間的電影信息
效果

(源碼在文章結(jié)尾)
主要涉及知識(shí)點(diǎn)
1、ASP.NET WEB MVC下的目錄結(jié)構(gòu)以及基礎(chǔ)編程
2、Linq查詢操作
3、Code First
4、各模板View的建立和使用
