#題目
1、使用Code First技術建立一個Movie資料模型。

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; }      //電影型別
        public decimal Price { get; set; }    //電影票價
        public string Rating { get; set; }     //電影分級
 }

2、使用MVC相關技術實現資料的列表顯示和新增功能。

3、完成資料的編輯、刪除、明細和條件查詢等功能。

4、完成如下查詢：
（1）查詢尚未上映電影的資訊
（4）查詢票價在某個區間的電影資訊
