What do you mean by "break a string"?
And where are newlines significant?
Strings don't have "breaks" and a newline is just a character or character sequence as far as a string is concerned. It's only when a string is output to a browser, display, or printer that line breaks become relevant - and then it depends on the environment what you do to perform a newline.
For example, outputting to a console:

C#

Console.WriteLine("Cana");
Console.WriteLine("nyon");

and

C#

Console.WriteLine("Cana\nnyon");

are equivelant, and put in two newlines.
But for a browser, you need HTML:

C#

Response.Write("Cana<br />nyon<br />");

Is needed.
For printing, or output to displays via Paint events, it gets even more complex.

Basically, a string isn't an "output-able" object, and it has no concept of a line break - so there is no "one size fits all" answer we can give.

Solution 2

Use the Environment.NewLine Property like this:

C#

string str = "Cana" + Environment.NewLine + "nyon" + Environment.NewLine + "whatever";

Solution 3

Is it about splitting into chunks of four characters?
How about this?

C#

string s = "Cananyoneshowsmehowtoaddthelinebreak";
while(s.Length > 4)
{
    Console.WriteLine(s.Substring(0,4));
    s = s.Substring(4);
}
if (s.Length > 0)
{
    Console.WriteLine(s);
}

Cheers
