`break` exists the while-loop immediately after the first execution. Remove it and replace the loop condition with an appropriate test. — Olivier Jacot-Descombes, Apr 22 '16 at 18:37

You need to remove

break;

Edit while condition and move

sd.Close();
fs.Close();

out of the while cycle.
So your while cycle should look like this

while (!sd.EndOfStream)
{                            
    s = sd.ReadLine();
    field = s.Split(std.delimiter);
    std.ID = field[0];
    std.Name = field[1];
    std.Address = field[2];
    std.Display_data();
}
sd.Close();
fs.Close();

`sd.RreadLine()` will throw `ObjectDisposedException` after `sd.Close()`. You need to move both of those `.Close()` calls outside of the `while` loop. – p.s.w.g Apr 22 '16 at 18:43

Read line,split using '@' and then read 3 line items and print out the lineitems.

using(StreamReader oReader = new StreamReader(@"E:\Newfolder\a\test.txt"))
{
    string [] sLineItems = oReader.ReadLine().Split('@');

    for(int i = 0;i < sLineItems.Length; i = i+3)
    {
          Console.WriteLine("Id:{0}",sLineItems[i]);
          Console.WriteLine("Name:{0}",sLineItems[i+1]);
          Console.WriteLine("Address:{0}",sLineItems[i+2]);
    }
}
