Basic regular expression

Hi

I need help removing some characters from an input string. When the input string is stored in sql server 2005 the characters appear as squares. What characters are these? I thought perhaps they were line breaks as there are 2 of these characters at the end of each line of text (by that i mean the 2 characters together encode a line break). Whatever they are i would like to remove them from my input and I don't know what regular expression i need to match them

many thanks

You can just do a replace

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

I think I've heard somewhere that the way linux and windows handles carriage returns is different, like I think windows used \n\r, where linux just does \n, so just to be safe I replaced both separately with an empty string.

You might want to copy the text into a text editor to verify that the boxes do indeed represent line breaks (most likely they are, but if they're not, you might as well know in advance).

Also,

    *nix: LF (\n)
    Windows: CR (\r) + LF (\n)

The average business loses $13.5M per year to ineffective training (per 1,000 employees). Keep ahead of the competition and combine in-person quality with online cost and flexibility by training with Linux Academy.
