Downloading Multiple Files as Zip Using Ionic.ZIp in ASP.NET MVC

We might come across a situation where we need to download multiple files and since a response cannot contain more than one file result; the best way to do is to zip all the content and download the zip file. 

Here's how we do it:

We need Ionic.Zip.Dll

We need 

using System.IO;
using Ionic.Zip;



 byte[] zipContent = null;
            using (var zip = new ZipFile())
            {
                zip.AddFile(Server.MapPath("~/Ionic.Zip1.dll"));
                zip.AddFile(Server.MapPath("~/Ionic.Zip2.dll"));
 
                //assign all zip content to content
                using (var ms = new MemoryStream())
                {
                    zip.Save(ms);
                    zipContent = ms.ToArray();
                }
            }
            Response.AppendHeader("Content-Disposition", string.Concat("inline; filename=\"", "download.zip", "\""));
            return File(zipContent, "zip");
