采用多种模式来看待
原标题:Passing multiple models to a view

我在阅读其他职位后发现,我需要建立一个单独的班级,即时进行这一班级,然后把即时班回来。 然而,我如何这样做?

我想利用实体框架和林克回答问题。 如果你能够为我学习提供样本代码......

最佳回答

你们也可以迅速、 d忙地利用活力:

dynamic viewdata = new ExpandoObject();
viewdata.object1 = Model1;
viewdata.object2 = Model2;

return View(viewdata);

或者,你可以适当地这样做,并形成一种看法。

class ViewModel1 {
  public MyModel Model1 { get; set; }
  public MyOtherModel Model2 { get; set; }
}

ViewModel1 viewdata = new ViewModel1();
viewdata.Model1 = Model1;
viewdata.Model2 = Model2;

return View(viewdata);
问题回答

用途

public ActionResult Index()
{
    SomeClass1 object1 = new SomeClass1();
    SomeClass2 object2 = new SomeClass2();
    ViewData["someName1"]=object1;
    ViewData["someName2"]=object2;
    return View(ViewData);
}

在“观点”网页上,你可以查阅:

<% SomeClass1  object1 = ViewData["someName1"] as SomeClass1; %>
<% SomeClass1  object2 = ViewData["someName2"] as SomeClass2; %>

建立观点模式。 一种观点模式通常由其他模式组成,不受您的数据模式的约束。 MvcMusic demo是使用观点模式的良好范例。

虽然将使其不安全,基本上取决于魔法,但我会避免。
