That's harder than you might think!
The problem is that text files don't have "lines" in the way you think of them: they just contain human readable characters one of which is interpreted by some - but not all - applications as an "end of line" character.
So you can't "write to line 2" because it isn't at a fixed place - where line two starts is immediately after the end of line character indicating the end of line one. And you can't "insert" to a text file, as when you write it will overwrite the existing characters.

So instead of that, read all the lines from your file when your app starts:
C#
private string[] lines;
...
lines = FileReadAllLines(pathToFile);
Then when you want to change line 1:
C#
lines[0] = line1.Text;
File.WriteAllLines(pathToFile, lines);
And the same for line 2:
C#
lines[1] = line2.Text;
File.WriteAllLines(pathToFile, lines);


BTW: Do yourself a favour, and stop using Visual Studio default names for everything - you may remember that "TextBox8" is the mobile number today, but when you have to modify it in three weeks time, will you then? Use descriptive names - "tbMobileNo" for example - and your code becomes easier to read, more self documenting, easier to maintain - and surprisingly quicker to code because Intellisense can get to to "tbMobile" in three keystrokes, where "TextBox8" takes thinking about and 8 keystrokes...
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
