Add \n to a string

Wayne,

I would use the replace method, and just realise that '\n' is a char just like 'a' and 'b'.  Also, the replace method can replace chars with chars, and ALSO strings with strings.  If you are looking for carraige returns in something like a large text box, I'd do something like the following:

inputString = inputString.Replace("\r\n", "\n");

This simply replaces carraige returns with a null terminator.  This is nice, because you can then output your new inputString to the console and it will still look correct.

-Eric

str.Replace(".", ".\n");

would add the \n to the end of the '.'.

Cheers
Wint.

Eric, there are instances when text is cut and paste inside a multiline textbox with out any carraige returns. I need to create those new lines once a full stop is found.

Wint, this code does not work, I am using c# so I have to use '' instead of "", when i do i can not use '.\n'

Cheers

Wayne

I work in C# and it worked fine in my test program....

class AddingNewLineChars
{
      [STAThread]
      static void Main(string[] args)
      {

            string ToEdit = "Hello. My. Name. Is. Winter.";

            string Edited = ToEdit.Replace(".", ".\r\n");

            Console.WriteLine("Original String: " + ToEdit);
            Console.WriteLine("New String:\r\n" + Edited);
            Console.ReadLine();
      }
}

Cheers Wint.

Wint, note sure if this has anything to do with it, but my project is web.

Cheers

It shouldn't affect it in any way as the string object is the same (I thought), though i'll be honest i haven't actually written anything for the web in a long time, but i'd be surprised if the Replace methods on a string are different.

Cheers

Wint.

Another way would be to use Regex:

using System;
using System.Text.RegularExpressions;

string myString;
myString = "This is a test.";
myString = Regex.Replace(myString, " .", " .\n");

(from http://www.123aspx.com/PostReview.aspx?res=276)

This should work with aspx...

Cheers
Wint.

I tried your code with a watch and it does do what it says on the tin, but on showing the txt back to the web form all is still the same.

Wayne

Did you try \r\n instead of \n?

Wint.

Wint, this replace every single character to a . - hey hey.

Cheers

Cheers Guys

For what it's worth, recommended guidelines are to use System.Environment.NewLine to support future cross-platform capability

Cheers

Also, when you use regular expressions you should learn what they are first. The '.' special character matches any character in the string. If you want to find '.' in the string - you should use "\." in the search pattern instead of just ".".

baldrick:

That's only for when writing to an output or input generated by your own platform. When parsing text coming from a potentialy unknown system you should always accept both the unix style as the windows style line ends jsut to be sure. (Or always convert to your own platform before parsing which is probably even better).

Regardless of your implementation, you should use  Environment.Newline instead of "\r\n"

There r two different problems here (that people spoke about) i wanted to differentiate between them,

u wanna put a carrige return after a fullstop in a text box ?? or directly to outuput ?? this differs

- If it's directly output Response.Write(.....); or Console.Write(....) then just replace the "." with ".\r\n"; it'll work just fine.

- If it's a text box then this will not work, u will have to replace with ".\xx\xd" to let the text box read those as a carriege return not just as regular characters.

hope this helps.
