如何使用linq命令來選擇此數據

Question

我有一個名爲attraction的表，它有一個id列，它是表的type的組合密鑰。

景點：ID，名稱，城市

價格：ID，型號，價格

我怎樣才能通過linQ在Visual Studio中選擇一排這樣的數據：

id, name, city, type1_price, type2_price 

Answer 1

You want to access anonymous type to some kind of object and to acheive this you can try like 
declare array of 
var data= new[] { new 
      { 
       Id= 0, 
       Name = "", 
       City = "", 
       Price1 = 0, 
       Price2 = 0, 
      } }.ToList(); 

then you can write query like 

data = (from a in attraction 
     join p in price on a.Id equals p.Id 
     select new 
     { 
       Id= a.Id, 
       Name = a.Name, 
       City = a.City, 
       Price1 = a.Price, 
       Price2 = p.Price, 
     }).ToList(); 

Try above
