Regular expressions in C#
-
Hi, I have an application where users can do many find/replace operations, including regexes. The problem is that if the user wants to replace something with a carriage return/newline and enter
\r\nit literally replaces with "\r\n", however if I try the same thing but in the code, and specify a regex to replace something with\r\nit does replace with a carriage return/newline. Otherwise the regex works properly, for example the user can find a carriage return/newline with\r\nand they can replace with$1for example, but it just doesn't work when you try and replace with\r\n. thanks for any help! -

string s = @"\r\n";orstring s = "\\r\\n";You could replace it manually within your code:string s = s.Replace(@"\r, "\r).Replace(@"\n", "\n"); -
