海外TECH	DEV Community	How to Upload and return files in ASP.NET MVC?	https://dev.to/ifourtechnolab/how-to-upload-and-return-files-in-aspnet-mvc-13j2	How to Upload and return files in ASP NET MVC In this blog we will shed light on how to upload and return a file in ASP NET MVC When a user uploads files they should be uploaded to their project folder We need to create a folder for the uploaded file in our project Let s get started with creating an MVC application Creating MVC ApplicationCreate a new MVC application for file uploading and downloading Adding FolderHere we created a folder in our project to store uploaded files Fig Storing Uploaded File We need to create a model class for file upload and return files Right click on Model Folder and add a class file Here I will use the code first approach to implement File upload and return functionality Place the following code inside the class file Filetables csusing System Collections Generic using System Web namespace Dynamicappendpartial Models public class Filetables public IEnumerable lt httppostedfilebase gt files get set public int Id get set public string File get set public string Type get set lt httppostedfilebase gt Right click on Models and add Ado Net Entity Data model Fig Empty Code First model This Empty code First model creates a context file for your database connection You can now add your Filetables class within the context file shown below using System using System Data Entity using System Linq namespace Dynamicappendpartial Models public class FileBlog DbContext public FileBlog base name FileBlog public virtual DbSet lt filetables gt Filetables get set lt filetables gt Now we need to execute all the required Migrations commands within the package manager control Read More Generate Thumbnail Using Asp net MVCWe need to add a controller Right click on the Controller folder and click on add gt controller Fig Creating Controller Select empty controller form list and give the suitable name of the controller Here I give controller name as Filetables And place the following code inside the controller Fig Add Controller FiletableControllerusing System using System Collections Generic using System Data using System Data Entity using System IO using System Linq using System Net using System Web using System Web Mvc using Dynamicappendpartial Models namespace Dynamicappendpartial Controllers public class FiletablesController Controller private FileBlog db new FileBlog GET Filetables public ActionResult Index List lt filetables gt ObjFiles new List lt

Message files uploaded successfully return RedirectToAction Index catch TempData Message File upload Failed return RedirectToAction Index lt filetables gt lt filetables gt Here I am creating two index methods one for uploading content to the database and one for uploading the file The first index method is used to retrieve the uploaded file list and display it on the index page On the same index page I will create a form to upload files in the database The Last Index method in the controller is for uploading a file on a server I want to store all files inside the upload file folder we created before starting the code And use the TempData to display the message after files are uploaded successfully If any exception occurs during execution or if the file was not uploaded successfully TempData shows File Uploaded Failed message on view In the controller I am creating one method for file Extension This method is used to display which type of file we uploaded to the database And also create a method for downloading an uploaded file Right click on the index method and add a view for the index method IndexView model IEnumerable lt dynamicappendpartial models filetables gt ViewBag

requirements For the Uploading file we have to require an input type file so we can select the file Searching for Reliable ASP NET Development Company Now run the application On index view you can show the choose file option Fig Index view for File Uploading If the file was upload successfully you can show the file upload successfully message in view Fig Uploaded file Display with the message If the file was not uploaded or we can click submit button without selecting the file it will display the File upload failed message in view Fig Uploaded file with the failed message Fig Uploaded file You can see all the uploaded files inside the folder we have created Click on the Download link to download the file Here I download all files you can show the downloaded file in the browser Fig
