Cannot pass a list from the controller to view

I'm trying to pass a list of values from the controller to the view, but apparently I got this issue where the list cannot be passed. I already tried passing one value and it has no problem. But when I try to pass list, it show the following error -

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[vidly.Models.pelanggan]', but this dictionary requires a model item of type 'vidly.models.pelanggan'.

I have this model -

public class pelanggan
{
    public string Nama { get; set; }
}

The controller code -

// GET: Pelanggan
public ActionResult Index()
{
    var name = new List<pelanggan> {
       new pelanggan {Nama = "Paidi" },
       new pelanggan {Nama = "Budi" }
    };

    return View(name);
}

This is my view file

@model vidly.Models.pelanggan

@{
    ViewBag.Title = "index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Customer</h2>

@foreach(var Nama in Model.pelanggan)
{
   <li>@Nama.Nama</li>
}

I already tried to create a ViewModel but it also showing same error. Can you point where the error is?

You are returning a List<T> from the controller. So, the model declared in your view should be able to receive a list and iterate over it.

Replace the model declaration in the view file with following -

@using vidly.Models;
@model IEnumerable<pelanggan>

Then you can iterate/loop over the model like -

@foreach(var p in Model)  // p represents a "pelanggan" object in the list 
{
   <li>@p.Nama</li>
}

The problem is the missmatch of types between what you return return View(name); and what te view expects @model vidly.Models.pelanggan You could change to @model List<vidly.Models.pelanggan> but instead I'd say:

    public class pelanggan
    {
        public List<string> Namas { get; set; }

    }

Then

        public ActionResult Index()
        {
            var model = new pelanggan {
             name = new List<string> {
                         "Paidi",
                         "Budi" 
                    }
              };

            return View(model);
        }

And finally in your view

       @foreach(var Nama in Model.Namas)
       {
           <li>@Nama</li>
       }
