MVC : Create text file and download

In this article I am going to explain how to create text file and download using asp.net MVC.

Description:

I want to write text enter in textbox to Text file and download that text file.

Implementations:

Add controller

First of all add an empty controller to project. Create Action to create text file and download.

Complete Code of Controller:

using System;

using System.Collections.Generic;

using System.Data;

using System.Data.Entity;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using System.IO;

using System.Text;

namespace mvctest2017.Controllers

{

    public class TextFileController : Controller

    {

        public ActionResult Index()

        {

            return View();

        }

        public ActionResult CreateTextFile()

        {

            return View();

        }

        [HttpPost]

        public ActionResult CreateTextFile(string message)

        {

            string path = Server.MapPath("~/aspmantra.txt");

            using (StreamWriter sw = System.IO.File.CreateText(path))

            {

                sw.WriteLine(message);

            }

            return File(path,"text/plain","aspmantra.txt");

        }

     

    }

}

Add view

Now add view to Createtextfile action.

Complete Source of View:

@{

    ViewBag.Title = "Create Text File";

}

@using(Html.BeginForm())

{

    <table>

        <tr>

            <td><label>Enter Text :</label></td>

            <td>@Html.TextArea("message", new { cols = 50, rows = 8 })</td>

        </tr>

        <tr>

            <td></td>

            <td><input id="Submit1" type="submit" value="Ctreate Text File" /></td>

        </tr>

    </table>   

}
