@using (Html.BeginForm("YourAction", "YourController"))
{
    @Html.AntiForgeryToken()
    "file" name="files" multiple>

    "submit" value="Upload File to Server">
}

[HttpPost]
    [ValidateAntiForgeryToken]
    public void YourAction(IEnumerable files)
    {
        if (files != null)
        {
            foreach (var file in files)
            {
                // Verify that the user selected a file
                if (file != null && file.ContentLength > 0)
                {
                    // extract only the fielname
                    var fileName = Path.GetFileName(file.FileName);
                    // TODO: need to define destination
                    var path = Path.Combine(Server.MapPath("~/Upload"), fileName);
                    file.SaveAs(path);
                }
            }
        }
    }
