ASP.NET實現(xiàn)電影票信息的增刪查改功能

 更新時間：2016年12月14日 10:08:36   作者：許佳佳233  
這篇文章主要介紹了ASP.NET實現(xiàn)電影票信息的增刪查改功能的相關(guān)資料,非常不錯，具有參考借鑒價值，需要的朋友可以參考下

題目

1、使用Code First技術(shù)創(chuàng)建一個Movie數(shù)據(jù)模型。

public class Movie
 {
  public int ID { get; set; }  //電影編號
  public string Title { get; set; }  //電影名稱
  public DateTime ReleaseDate { get; set; } //上映時間
  public string Genre { get; set; }  //電影類型
  public decimal Price { get; set; } //電影票價
  public string Rating { get; set; }  //電影分級
 }

2、使用MVC相關(guān)技術(shù)實現(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）查詢票價在某個區(qū)間的電影信息

效果

這里寫圖片描述

（源碼在文章結(jié)尾）

主要涉及知識點

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
