How : To Read A Text File In C# - Trickcode

Read A Text File In C#

Reading data from a text file is almost similar to writing data to it. You create a FileStream pointing to the file to be read. But instead of passing the stream to a StreamWriter class, we used the StreamReader class which contains a method to read data from a file. The following program demonstrates the reading of the file.

using System;
using System.IO;
using System.Text;
 using System.Collections.Generic;

    namespace ReadingFromFile
   {
        class Person
    {
       public string FirstName { get; set; }
          public string LastName { get; set; }
         public int Age { get; set; }
      }
 
    class Program
     {
         static void Main()
         {
            List persons = new List();
 
             try
            {
              FileStream fs =
                      new FileStream("sample.txt", FileMode.Open, FileAccess.Read);
                 StreamReader reader = new StreamReader(fs);
 
                while (!reader.EndOfStream)
                  {
                    string line = reader.ReadLine();
                     string[] fields = line.Split('#');
                    Person newPerson = new Person();
                    newPerson.FirstName = fields[0];
                      newPerson.LastName = fields[1];
                    newPerson.Age = Convert.ToInt32(fields[2]);
                    persons.Add(newPerson);
                }
             }
             catch (IOException ex)
          {
                 Console.WriteLine(ex.Message);
           }
  
          //Show each person's details
             foreach (Person p in persons)
             {
               Console.WriteLine("Name: {0} {1}\nAge: {2}",
                    p.FirstName, p.LastName, p.Age);
              }
        }
       }
   }
