創建匿名類型對象並傳入MVC＃剃鬚刀視圖？

Question

Q1：什麼是以下更好的簡寫版本？ Q2：如何將匿名類型傳遞給我在mvc3中的視圖？

public ViewResult Index3() 
    { 
     List<T1> ls = new List<T1>(); 
     ls.Add(new T1 { id = 1, title = "t1", val1 = 1, val2 = 2}); 
     ls.Add(new T1 {id=2, title="t2", val1=3, val2=4}); 
     ls.Add(new T1 { id = 3, title = "t3", val1 = 5, val2 = 6}); 

     return View(ls); 
    } 

（Q1）東西類似於?:

 List<T1> ls = new List<T1>(
      List<T1>(new { id = 1, title = "t1", val1 = 1, val2 = 2} 
      new { id = 2, title = "t2", val1 = 3, val2 = 4}) 
     ); 

（Q2）東西類似於?:

public ViewResult Index3() 
    {       
     return View(List(new { id = 1, title = "t1", val1 = 1, val2 = 2 } 
      new { id = 2, title = "t2", val2 = 3, val2 = 4 } 
     ); 
    } 

然後引用上述剃刀視圖：

@model IEnumerable<Some Anonymous or Dynamic Model> 

    @item.id 
    @item.title 
    @item.val1 
    ... 

Answer 1

Q1是一個偏好問題。編譯器在內部創建類似的代碼時沒有性能差異。

Q2是不可能的，您必須創建一個非匿名類型才能訪問它。

Answer 2

可以使用ViewBag將您的列表傳遞給視圖。

Answer 3

1. 集合初始化是這樣寫的：

   List<T1> ls = new List<T1> { 
       new T1 { id = 1, title = "t1", val1 = 1, val2 = 2 }, 
       new T1 { id = 2, title = "t2", val1 = 3, val2 = 4 }, 
       new T1 { id = 3, title = "t3", val1 = 5, val2 = 6 } 
   }; 
   

2. 創建一個隱式類型數組：

   return View(new [] { new { id = 1, ... }, ... }); 
   

Answer 4

也不選項將作爲匿名類型內部和剃刀視圖被編譯成一個單獨的程序集。
