Why aren't these strings displayed in separate lines?

Question

write the contents of person in a file

FirstName: Abcd

SecondName: Tsfsdfs

For this I wrote a sample application

namespace BinaryStream
{
    class Program
    {
        static void Main(string[] args)
        {
            StreamWriter binWriter = new StreamWriter(@"c:\happybirthday.txt");
            string name = "Sachin";
            string secondname = "tendulkar";
            string wishes = "happy birthday";

            string firstname = string.Format("FirstName: {0} \n", name);
            binWriter.Write(firstname);
            string sn = string.Format("SecondName: {0} \n", secondname);
            binWriter.Write(sn);
            binWriter.Close();          
        }
    }
}

IF I open the contents in the notepad, the strings are not displayed in the next line What is the reason for this? Is the format part is correct?

You need to use WriteLine, not Write. Write does not put a linefeed\cr at the end of the line. Placing \n in the text only places a linefeed, and does not place a cariage return.

He's trying to put linebreaks in the string itself. (Although WriteLine would be a better way of doing this...) – Rawling Apr 24 '12 at 15:02
It's actually the carriage return (`\r`) that's missing; the linefeed is alread in his format strings. – Gabe Apr 24 '12 at 15:03
Also, he'd see those newlines without \r w/ wordpad and not notepad – payo Apr 24 '12 at 18:34
@payo - that's because wordpad has code to replace the standalone lf's with cr/lf, notepad does not. – Erik Funkenbusch Apr 24 '12 at 18:38
@MystereMan how it does it is another issue, on a side note, how do you know it literally injects \r's, and doesn't just render the \n sufficiently? – payo Apr 24 '12 at 20:17
@payo - because when the document is resaved, it replaces the \n's with \r\n's – Erik Funkenbusch Apr 24 '12 at 20:45

You require both a carriage return and a line feed. You only have a line feed. Replace your \n with \r\n and you'll see it correctly in notepad.

You may find that you need a combination of a Carriage Return (CR) and a Line Feed (LF) character, not just the LF.

So - in your code, replace the \n with \r\n

which is one is correct \r\n or \n\r. As john said it should be \n\r for the newline in windows – Raghav55 Apr 24 '12 at 15:05

It's \r\n - as discussed here: http://stackoverflow.com/questions/6539801/reminder-r-n-or-n-r – Chris Roberts Apr 24 '12 at 15:07

For starters, you are creating a binary file rather than a text file. This is probably confusing Notepad.

Besides in C# the \n means LF only, you must use \r\n (CR - LF).

Just write this:

string[] lines = {"FirstName: Abcd", "SecondName: Tsfsdfs"};
System.IO.File.WriteAllLines(@"c:\happybirthday.txt", lines);

This isn't a C# thing, it has to do with the program reading the file. Notepad requires \r\n, winword deals with \n or \r\n just fine, as do many other programs. – Servy Apr 24 '12 at 15:08

New line is \n\r in windows. But some programs are intelligent enough to understand just \n. Others, like notepad - are not.

Basically, instead of using the string escape character, use `Environment.NewLine` – Tejs Apr 24 '12 at 15:02
Actually, newline is \r\n, not \n\r. It does make a difference. – Erik Funkenbusch Apr 24 '12 at 18:38
