MVC View Foreach Var in Model?

Need help understanding this View foreach issue. Get an error within the view foreach:
 
                     "Message='System.Array' does not contain a definition for 'evals'"

I have debugged the controller and verify data is present in -> (return View(evals);)


[HomeController]
 public class HomeController : Controller
    {
        EvalServiceClient client = new EvalServiceClient("WSHttpBinding_IEvalService");        

        public ActionResult Index()
        {
            Eval eval = new Eval();
            eval.Comments = "This came from code!";
            eval.Submitter = "Aaron";
            eval.TimeSubmitted = DateTime.Now;

            client.SubmitEval(eval);

            Eval[] evals = client.GetEvals();

            //foreach (Eval ev in evals)
            //    Console.WriteLine(ev.Comments);

            return View(evals);
        }

        public ActionResult About()
        {
            return View();
        }
    }

[View]

@{
    ViewBag.Title = "Home Page";
}

<h2>@ViewBag.Message</h2>
<p>

<div>
    <div id="Tags">
           @foreach (var ev in Model.evals)
            {
                @ev.comments
            }
        </div>
</div>

Hi,

Check this sample  -

HomeController
        public ActionResult Index()
        {
            ViewBag.Message = "Welcome to ASP.NET MVC!";

            Student[] student = new Student[]{
                new Student{
                        RollNo = 1,
                        Name = "Bill",
                        Branch = "CSE"
                },

                new Student{
                        RollNo = 2,
                        Name = "Steve",
                        Branch = "CSE"
                },
                new Student{
                       RollNo = 3,
                       Name = "Larry",
                       Branch = "CSE" 
                }
            };

            return View(student);
        }

Open in new window


View - Index

<div id="Tags">
    <ul>
        @foreach (var item in Model)
        {
            <li>
                @item.Name
            </li>
        }
    </ul>
</div>

Open in new window

In this case the Model doesn't contain a property called evals, the model is the evals. Your foreach should just be:

@foreach( var item in Model )

Your example works perfectly. I'm working with a Service Reference. Your example is not working with my Service Reference.

Hi,

Again, we should see what your Service Reference is returning!

Check whether it is returning the correct data!

Got it!

[controller]
return View(evals);

[view]
 @foreach (var item in Model)
            {
               <li>@item.Comments</li>                    
            }

What error are you getting after making the change to the foreach in your view? I wouldn't think you're getting the same error anymore. Model was an array of Eval, and saying Model.evals was saying, "get me the 'evals' property of the array represented by Model", which is why you got the error saying System.Array doesn't have an "evals" property.

Changing the foreach as both our posts told you to do should at least have resulted in a different error.
