You can use Request.Files or through view models with property:
public IEnumerable<HttpPostedFileBase> files {get;set;}
Just replace your code with IEnumerable. If you want to use Request.Files then you should change your code structure to:
foreach (string requestFileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[requestFileName];
string filename = Path.GetFileName(file.FileName);
string contentType = file.ContentType;
string folder = Server.MapPath("~/Files");
using (Stream fs = file.InputStream)
{
using (BinaryReader br = new BinaryReader(fs))
{
byte[] bytes = br.ReadBytes((Int32)fs.Length);
file.SaveAs(Path.Combine(folder, filename));
}
}
}

You Can use the below code sample for do the upload multiple file together.
Html Code:-
<html>
<head>
<title>Index</title>
</head>
<body>
<div>
@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<span>Select File:</span>
<input type="file" name="postedFiles" multiple="multiple"/>
<hr/>
<input type="submit" value="Upload"/>
<br/>
<span style="color:green">@Html.Raw(ViewBag.Message)</span>
}
</div>
</body>
</html>
Controller:-
ease refer my article Display (Pass) String Message from Controller to View in ASP.Net MVC.
public class UploadController : Controller
{
// GET: Home
[HttpPost]
public ActionResult Index(List<HttpPostedFileBase> postedFiles)
{
string path = Server.MapPath("~/Uploads/");
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
foreach (HttpPostedFileBase pFile in postedFiles)
{
if (postedFile != null)
{
string fileName = Path.GetFileName(pFile.FileName);
pFile.SaveAs(path + fileName);
ViewBag.Message += string.Format("<b>{0}</b> uploaded.<br />", fileName);
}
}
return View();
}
}
