正则表达式从C＃中的字符串中删除\\ n \\（不是\\ n）

Question

I am looking for a 'Regex' to replace \\n\\ from my string. I already looked thorough this post and other regex posts here, but in my case I need to remove the value \\n\\ from a string not a new line or ( \\n ).

For example:

string eneteredString = @"abc\n\def\n\ghi\n\\";

Here \\\\ can be found multiple times too.

I have already tried Replacing Enviornment.NewLine , as it is not a new line in my case, it also didn't work. When I try below code,

string regout = Regex.Replace(enteredString, @"\n\","");

It says parsing "\\n\\" - Illegal \\ at the end of pattern . Can you anyone please help me with the same. Thanks in advance.

Answer 1

Who need regex?

string regout = @"abc\n\def\n\ghi\n\\".Replace(@"\n\", "");

And just because quotes are cool, here is the famous :

Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.

Answer 2

use @"\\\\n\\\\" . You need to remove the meaning of the escape character \\ by adding a \\ before it.. Here is a testing image

Answer 3

This is what you want. The reason is due to how regex handles the single \\

string regout = Regex.Replace(enteredString, @"\\n\\","");
