StreamReader And StreamWriter In C#

In given code, you will learn to use of StreamReader and StreamWriter class to perform read and write operation using C#.Net.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace File_Example
{
class Program
{
public void WriteOperation()
{
FileStream fs = new FileStream("d:\\test.txt",FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter w = new StreamWriter(fs);
w.WriteLine(Console.ReadLine());
w.Close();
fs.Close();
}
public void ReadOperation()
{
FileStream fs = new FileStream("d:\\test.txt", FileMode.Open, FileAccess.Read);
StreamReader r = new StreamReader(fs);
int counter = 0;
while(!r.EndOfStream)
{
Console.WriteLine(r.ReadLine());
counter++;
}
Console.WriteLine(counter);
r.Close();
fs.Close();
}
static void Main(string[] args)
{
Program p = new Program();
p.WriteOperation();
p.ReadOperation();
}
}
}

Note: I just create a program to use of StreamReader and StreamWriter class from System.IO namespace.
