Read and Write to a Text File

[sde]

This is a very simple way to read and write to a text file using TextReader and TextWriter.

First you need to include System.IO

using System.IO;

Reading a Text File:

static void Main(string[] args)
{
  // create reader & open file
  TextReader tr = new StreamReader("date.txt");

  // read a line of text
  Console.WriteLine(tr.ReadLine());

  // close the stream
  tr.Close();
}

Writting a Text File

static void Main(string[] args)
{
  // create a writer and open the file
  TextWriter tw = new StreamWriter("date.txt");

  // write a line of text to the file
  tw.WriteLine(DateTime.Now);

  // close the stream
  tw.Close();
}
