In this article I will explain with an example, how to upload multiple files with Progress Bar using AngularJS ngFileUpload in ASP.Net MVC Razor.
You will need to import the following namespace.
using System.IO;
The Controller consists of two Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
Action method for handling POST operation
This Action method handles the call made from the AngularJS client for upload.
It first loops through the Request.Files collections and then inside the loop, each file is saved in the folder named Uploads.
Finally a success response is sent back to the AngularJS client.
public class HomeController : Controller
    // GET: Home
    public ActionResult Index()
        return View();
    public ContentResult Upload()
        string path = Server.MapPath("~/Uploads/");
        if (!Directory.Exists(path))
        foreach (string key in Request.Files)
            HttpPostedFileBase postedFile = Request.Files[key];
            postedFile.SaveAs(path + postedFile.FileName);
        return Content("Success");
The View consists of an HTML DIV to which ng-app and ng-controller AngularJS directives have been assigned.
Note: If you want to learn more about these directives, please refer my article Introduction to AngularJS.
The HTML DIV consists of an HTML FileUpload element for which the multiple property is set, so that user can select multiple files.
The HTML FileUpload element has also been assigned the ngf-select directive so that when files are selected in the HTML FileUpload element, it makes call to the UploadFiles function inside the AngularJS controller.
The selected files are sent to the Controller’s Action method using the Upload function of the ngFileUpload AngularJS module.
Timeout function has been used which periodically checks the response of the upload and it updates the Progress Bar.

                        data: {

                    }, function (response) {
                        if (response.status > 0) {
                            var errorMsg = response.status + ': ' +;
                    }, function (evt) {
                        var element = angular.element(document.querySelector('#dvProgress'));
                        $scope.Progress = Math.min(100, parseInt(100.0 * evt.loaded /;

        <ul><li ng-repeat="file in SelectedFiles">{{}}</li></ul>
        <div id="dvProgress" class="progress" ng-show="Progress >= 0">
Uploading Large files
In order to upload large files, you will need to
1. Set the following setting in the system.web section of the Web.Config file. The executionTimeout value is set to 540 seconds while the maxRequestLength is set to the maximum size of the files in Bytes.
<httpRuntime targetFramework="4.5" executionTimeout="540" maxRequestLength="904857600" />
2. Set the following setting in the system.webServer section of the Web.Config file. The maxAllowedContentLength is set to the maximum size of the files in Bytes.
     <requestLimits maxAllowedContentLength="904857600"></requestLimits>
