Upload multiple files in mvc razor using Jquery

Introduction: In this article today I am going to explain how to upload multiple files in mvc razor using jquery
Upload multiple files in mvc razor using Jquery


To upload multiple files I use the JQuery MultipleFile Upload Plugin.To implement the functionality in project follow the below given steps:

Step 1: Download the JQuery MultipleFile Upload Plugin and keep it in Js/Script folder of project.

Step 2: Add a class to Model. In this example I add a class Fileupload.cs to Model.
using System.ComponentModel.DataAnnotations;
public class Fileupload
        public int ID { get; set; }
        public string FileName { get; set; }
        public string FilePath { get; set; }

Step 3: Add the Fileupload class to Project DBcontext:
public DbSet<Fileupload> fileuploads { get; set; }

Step 4: Add a controller to project. I add an empty controller to project FileuploadController. Write the below given code in FileuploadController.cs file:
using fileupload.Models;
using System.IO;
public class FileuploadController : Controller
        Projectcontext db = new Projectcontext();
        // GET: /Fileupload/

        public ActionResult Index()
            return View(db.fileuploads.ToList());
        public ActionResult Index(IEnumerable<HttpPostedFileBase> files, Fileupload upload)
            foreach (var file in files)
                if (file.ContentLength > 0)
                    var fileName = Path.GetFileName(file.FileName);
                    var guid = Guid.NewGuid().ToString();
                    var path = Path.Combine(Server.MapPath("~/uploads"), guid + fileName);
                    string fl = path.Substring(path.LastIndexOf("\\"));
                    string[] split = fl.Split('\\');
                    string newpath = split[1];
                    string imagepath = "~/uploads/" + newpath;
                    upload.FileName = fileName;
                    upload.FilePath = imagepath ;
            return RedirectToAction("Index");

Step 5: Add a view for FileuploadController.  Add the Jquery reference to view.
@model IEnumerable<fileupload.Models.Fileupload>

    ViewBag.Title = "Upload File and Display";
    WebGrid grid = new WebGrid(Model, rowsPerPage:5);

<script src=""></script>
 <script src="js/jquery.MultiFile.js" type="text/javascript"></script>

@using (Html.BeginForm("", "", FormMethod.Post, new { enctype = "multipart/form-data" }))
    <table><tr><td><label for="file">Upload File:</label></td><td><input type="file" name="files" id="file" Class="multi"/></td></tr>
        <tr><td></td><td>  <input type="submit" /></td></tr>

  tableStyle: "table",

    fillEmptyRows: true,    
    headerStyle: "header",  
    footerStyle: "grid-footer",
    mode: WebGridPagerModes.All,
    firstText: "<< First",
    previousText: "< Prev",
    nextText: "Next >",
    lastText: "Last >>",
    columns: new[]  // colums in grid
        grid.Column("FileName"), //the model fields to display
       grid.Column("FilePath",format: @<text><img src="@Url.Content(item.FilePath)" alt="Image" height="100px" width="100px" /></text>)   

Build the project and run.
