How to eliminate ALL line breaks in string?

Question

I have a need to get rid of all line breaks that appear in my strings (coming from db). I do it using code below:

value.Replace(\"\\r\\n\", \"\").Replace(\"\\n\"         


        

Answer 1

If you've a string say "theString" then use the method Replace and give it the arguments shown below:

theString = theString.Replace(System.Environment.NewLine, "");

Answer 2

Props to Yossarian on this one, I think he's right. Replace all whitespace with a single space:

data = Regex.Replace(data, @"\s+", " ");

Answer 3

According to wikipedia, there are numerous line terminators you may need to handle (including this one you mention).

LF: Line Feed, U+000A
VT: Vertical Tab, U+000B
FF: Form Feed, U+000C
CR: Carriage Return, U+000D
CR+LF: CR (U+000D) followed by LF (U+000A)
NEL: Next Line, U+0085
LS: Line Separator, U+2028
PS: Paragraph Separator, U+2029

Answer 4

This is my first attempt at this, but I think this will do what you want....

var controlChars = from c in value.ToCharArray() where Char.IsControl(c) select c;
foreach (char c in controlChars)  
   value = value.Replace(c.ToString(), "");

Also, see this link for details on other methods you can use: Char Methods

Answer 5

I'd recommend removing ALL the whitespace (char.IsWhitespace), and replacing it with single space.. IsWhiteSpace takes care of all weird unicode whitespaces.

Answer 6

Assuming that 8232 is unicode, you can do this:

value.Replace("\u2028", string.Empty);
