Question

I want to match " inside a string but I am not able to add " to the list

Current my regular expression is

Regex.Replace(str, @"[\\/:*?<>|]","", RegexOptions.Compiled);

I also want to add "

\" is not accepted.

Answer 1

You need to escape " to "".

Use "" with verbatim strings..

i.e @"[\\/:*?<>|""]"

OR

Just use \" without verbatim strings.

i.e "[\\/:*?<>|\"]"

A character that is preceded with forward slash \ is treated as a special character..

For example.. \t,\n,\r are special characters..

But \e is not a special character since e has no special meaning..So,compiler would show you compile time error Unrecognized escape sequence

In order to treat characters preceded by \ literally(i.e to make it non special character) we use verbatim string i.e @""
