Reading from a local text file into C#? [closed]

Answer 1

You have the complete program (ASP.net). You must have a file inside the App_Data folder inside your ASP.net app, In this App your file name "Details.txt" which should be available inside your App_Data folder.

You have Hidden-field and a paragraph available in your web page. When form loads, at that moment read the data from the text file and populate to the Hidden-field control. And in $(document).ready() Jquery function populate data to paragraph from Hidden-field.

Your .aspx page :

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="ReadFromTextFileToTextBoxWebApp._Default" %>


  
  
  


    

        Welcome to ASP.NET!
    
     

        
        

        
     

and here is your code behind page :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;

namespace ReadFromTextFileToTextBoxWebApp
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            var data = File.ReadAllText(Server.MapPath("~/App_Data/Details.txt"));
            HiddenField1.Value = data.ToString();   
        }           
    }
}
