Question

How to replace the below string in C#

Current:

"John K "GEN" Greg"

The Goal:

 "John K \"GEN\" Greg"

This is wrong because I’m not escaping it properly:

s = s.Replace(""","\"");

What is syntax for replacing quotes with \ (slash)?

Any help would be appreciated.

Thanks

Answer 1

s = s.Replace("\"", "\\\"");

or

s = s.Replace(@"""", @"\""");

In the first example the " has to be escaped with a backslash as it would otherwise end the string. Likewise, in the replacement string \\ is needed to yield a single backslash by escaping the escape character.

In the second example verbatim string literals are used, they are written as @"...". In those literals no escape sequences are recognized, allowing you to write strings that contain lots of backslashes in a much cleaner way (such as regular expressions). The only escape sequence that works there is "" for a single ".
