Answer 1

1. Create a model which contains your list and other things you need for the view.

   For example:

   public class MyModel
   {
       public List<string> _MyList { get; set; }
   }
   

2. From the action method put your desired list to the Model, _MyList property, like:

   public ActionResult ArticleList(MyModel model)
   {
       model._MyList = new List<string>{"item1","item2","item3"};
       return PartialView(@"~/Views/Home/MyView.cshtml", model);
   }
   

3. In your view access the model as follows

   @model MyModel
   foreach (var item in Model)
   {
      <div>@item</div>
   }
   

I think it will help for start.

Answer 2

I did this;

In controller:

public ActionResult Index()
{
  var invoices = db.Invoices;

  var categories = db.Categories.ToList();
  ViewData["MyData"] = categories; // Send this list to the view

  return View(invoices.ToList());
}

In view:

@model IEnumerable<abc.Models.Invoice>

@{
    ViewBag.Title = "Invoices";
}

@{
  var categories = (List<Category>) ViewData["MyData"]; // Cast the list
}

@foreach (var c in @categories) // Print the list
{
  @Html.Label(c.Name);
}

<table>
    ...
    @foreach (var item in Model) 
    {
      ...
    }
</table>

Hope it helps

You can use the dynamic object ViewBag to pass data from Controllers to Views.

Add the following to your controller:

ViewBag.MyList = myList;

Then you can acces it from your view:

@ViewBag.MyList

// e.g.
@foreach (var item in ViewBag.MyList) { ... }

Passing data to view is simple as passing object to method. Take a look at Controller.View Method

protected internal ViewResult View(
    Object model
)

Something like this

//controller

List<MyObject> list = new List<MyObject>();

return View(list);


//view

@model List<MyObject>

// and property Model is type of List<MyObject>

@foreach(var item in Model)
{
    <span>@item.Name</span>
}
