================================================================================= sorry to confusing you all actually im really lacking experience in programming and i hardly know how to use it
right now im using vs2012 in windows8 , is that mean i was coding in winrt?

btw , i appreciate all your help and successfully applying answer to my code this is the actual code

        var file = await ApplicationData.Current.LocalFolder.GetFileAsync(tb1.Text+".txt");
        var line = await FileIO.ReadLinesAsync(file);
        if (tb2.Text == line[2])
        {
            tb3.Text = (line[1]);
        }

var desiredText = File.ReadLines("C:\myfile.txt").ElementAt(1);

File.ReadLines() returns an IEnumerable<String> of the lines in a file. The index of the second line is 1. See this.

File.ReadAllLines returns `String[]`, not `IEnumerable`. Index does not work on `IEnumerable` – Tilak Dec 01 '12 at 11:33
Whoops, thanks @Tilak. It's 3 AM here, not fully awake yet. :) Fixed. – tallseth Dec 01 '12 at 11:35
You mean it returns an IEnumerable and not string[] – Ric Dec 01 '12 at 11:36
Code was correct. Index works on array. My comment was for your explanation. Take Beer first :) – Tilak Dec 01 '12 at 11:36

try

var desiredText = File.ReadLines("C:\myfile.txt");
textbox1.text = desiredText[1];

Just call a .ReadLine() before you start capturing the content of the file.

Essentially this will make the reader skip the first line of the file and take only the 2nd line and all lines that follow it.

// Try this to take the second line.
string line;
using (var file_read = new StreamReader(your_file))
{
    file_read.ReadLine(); 
    line = file_read.ReadLine();
}
textBox1.Text = line.ToString();

read the second line from the text
