How to display a list using ViewBag

Question

Hi i need to show a list of data using viewbag.but i am not able to do it.
Please Help me..
I tried this thing:

 ICollection<Learner> list = new HobbyHomeService().FetchLearner();  ICollection<Person> personlist = new HobbyHomeService().FetchPerson(list);  ViewBag.data = personlist; 

and inside view:

 <td>@ViewBag.data.First().FirstName</td> 

But this does not show up the value and gives error saying "Model.Person doesnot contain a defibition for First()"

Answer 1

In your view, you have to cast it back to the original type. Without the cast, it's just an object.

<td>@((ViewBag.data as ICollection<Person>).First().FirstName)</td> 

ViewBag is a C# 4 dynamic type. Entities returned from it are also dynamic unless cast. However, extension methods like .First() and all the other Linq ones do not work with dynamics.

Edit - to address the comment:

If you want to display the whole list, it's as simple as this:

<ul>     @foreach (var person in ViewBag.data)     {         <li>@person.FirstName</li>     } </ul> 

Extension methods like .First() won't work, but this will.

To put it all together, this is what it should look like:

In the controller:

List<Fund> fundList = db.Funds.ToList(); ViewBag.Funds = fundList; 

Then in the view:

@foreach (var item in ViewBag.Funds) {     <span> @item.FundName </span> }
