I did it, In my View

 <ul>
            @foreach(var Item in(IEnumerable<Marjaa.Data.MultimediaFile>) ViewData["Files"]) 
            {

               <li><a href=" @Url.Content("~/Content/Uploads/" + System.IO.Path.GetFileName(Item.MultimediaFileUrl))">@System.IO.Path.GetFileName(Item.MultimediaFileUrl)</a> </li>
             }                
            </ul>

From my Controller Just Sent a list to View

IList<MultimediaFile> list = d.MultimediaFiles.Where(l => l.MultmediaId == id).ToList();
        ViewData["Files"] = list;

Many different ways to do this. Here's one:

Create a class for your files

public class Image
        {
            public string Name { get; set; }
            public string Path { get; set; }
        }

and a view model class

public class ViewModel
        {
            public List<Image> Images { get; set; }
            public string Path { get; set; }
        }

Then in your controller, populate the view model and the name and path properties for each Image object in the list. You'll need to import the System.IO namespace. 

public ActionResult DisplayFilesForDownload( )
        {
            var viewModel = new ViewModel
            {
                Path = @"D:\Maarjaa\Marjaa\Content\Uploads", 
                Images = new List<Image>()
            };
            var paths = Directory.GetFiles(viewModel.Path).ToList();
            foreach (var path in paths)
            {
                var fileInfo = new FileInfo( path );
                var image = new Image
                {
                    Path = path, Name = fileInfo.Name
                };
                viewModel.Images.Add(image);
            }
            return View( viewModel);
        }

And the method to allow downloads. I am assuming all your files are images. If not, just adjust the MediaTypeName as needed.

public FileResult Download(string filePath, string fileName)
        {
            var file = File(filePath, System.Net.Mime.MediaTypeNames.Image.Jpeg, fileName);
            return file;
        }

and finally the view. Image.Name is used to display the shortened file name and Image.Path is used to tell the download method where to fetch the file from.

@model FullyQualified.Path.ToYour.ViewModel

@foreach (var image in Model.Images)
{
    <p>@Html.ActionLink(image.Name, "Download", "ControllerName", new{filePath = image.Path, fileName = image.Name}, null)</p>
}

Hope this helps get you on your way.
