如何在视图中设置多个对象？

public ActionResult Index()
{            
    var shops = this.context.shops.Select(q => new { q.id, q.name }).ToList();
    var bikes = this.context.bikes.Select(q => new { q.id, q.name }).ToList();
    return View(shops, bikes); // How to set two values in View()?
}

在View（）中解析

@foreach (var r in Model.bikes)
{
    <b>@r.name</b>
}

Answer 1

一种方法是创建一个包含商店和自行车的强类型视图模型。其他选项可能是创建一个元组并作为模型传递给视图。我会先选择。

元组

var tuple = new Tuple<shop, bike>(new shop(),new bike());

在你看来

@Model Tuple<shop,bike>

Answer 2

您的模型类应包含商店和自行车的属性。也就是说，如果您使用强类型视图，它看起来就是这样。否则，您可以向ViewBag添加内容以供在视图中使用。

Answer 3

您需要创建ViewModel

   public class shopsAndbikes 
    {
     public List<shop> shops {get;set;}
     public List<bike> bikes {get;set;}

    }

    public ActionResult Index()
    {             
       shopsAndbikes vm = new shopsAndbikes ()
       {
        var shops = this.context.shops.Select(q => new { q.id, q.name }).ToList();
        var bikes = this.context.bikes.Select(q => new { q.id, q.name }).ToList();
       }
      return View(vm);    
    }

查看：

@model shopsAndbikes 

@foreach (var r in Model.bikes)
{
    <b>@r.name</b>
}

@foreach (var r in Model.shops)
{
    <b>@r.name</b>
}
