在asp.net MVC视图中显示列表

Question

I receive a List of objects in my controller from my asp.net web application. How can I pass this list to the view2 and display it?

Controller

public class HomeController:Controller
{
 public ActionResult Index()
 {
  WCF.CommunicationServiceClient Client = new WCF.CommunicationClient("BasicHttpBinding_ICommunicationService");
  List<object> objectlist = Client.GetList("_something_");

  return View("ShowView");
 }
}

My biggest Problem is that this "object" is defined in another solution.

Answer 1

You need to pass the objectlist as view model to the view. I think the dynamic class will come in handy when defining your @model on the view.

Basic MVC really.

Answer 2

创建一个强类型的视图，然后像return View(objectlist );一样将对象传递给它return View(objectlist );

Answer 3

You can use the dynamic instead of Object in the List like this, As you don't know what the object have grab.

 public class HomeController:Controller
 {
   public ActionResult Index()
    {
     WCF.CommunicationServiceClient Client = new WCF.CommunicationClient("BasicHttpBinding_ICommunicationService");
     List<dynamic> objectlist = Client.GetList("_something_");
     return View("ShowView");
    }
 }

Answer 4

My biggest Problem is that this "object" is defined in another solution.

You should define your object in another project. For example, 'DataTransferObjects'. Then you add a reference to this project in both your WCF Server project and your MVC (WCF Client) project. This way the class will be known by both.

In your DTO project:

[DataContract]
public class MyClass
{
    [DataMember]
    public int MyProperty { get; set; }
}

Then your code would be:

public class HomeController:Controller
{
 public ActionResult Index()
 {
  WCF.CommunicationServiceClient Client = new WCF.CommunicationClient("BasicHttpBinding_ICommunicationService");
  List<MyClass> objectlist = Client.GetList("_something_");

  return View("ShowView", objectlist);
 }
}

And your ShowView:

@model List<MyClass>

@for (i = 0; i < Model.Count; i++)
{
    @Html.EditorFor(m => Model[i].MyProperty)
}
