how to use seek method to display first , middle, last character in text file using file streams in C# code

Try the following:

using System;

using System.IO;

class Test

{

static void Main()

{

FileStream fs = new FileStream("akila.txt", FileMode.Open, FileAccess.Read);

int first = fs.ReadByte();

Console.WriteLine("First character is {0}", (char)first);

long len = fs.Length;

fs.Seek(len/2, SeekOrigin.Begin);

int middle = fs.ReadByte();

Console.WriteLine("Middle character is {0}", (char)middle);

fs.Seek(-1, SeekOrigin.End);

int last = fs.ReadByte();

Console.WriteLine("Last character is {0}", (char)last);

fs.Close();

Console.ReadKey();

}

}

akila.txt is assumed to be an ASCII text file containing : i'm from coimbatore.

The output should be:

First character is i

Middle character is c

Last character is e
