C# Regular Expression - Adding Special Characters

Question

I was wondering what is the best way to include backslash and other special characters in a group?

example:

"message":"\"rock on\" \\,,/,[-_-]";

help me on my regex

[a-zA-Z0-9 \\-~!@#$%^*()_+{}:|?`;',\\./\\[\\]]+

can you elaborate on what you're trying to do? what exactly is the "example" you've given, and what do you want to do with the regex? What's the goal? — Cheeso

Just escape those that need to be escaped and add those, that don't need to:

[a-zA-Z0-9 \\\-~!@#$%^*()_+{}:|"?`;',./[\]]+

To elaborate a bit:
You only need to escape \, ] and - inside a character group.

Using C#, it would look like this:

Regex rx = new Regex(@"[a-zA-Z0-9 \\\-~!@#$%^*()_+{}:|""?`;',./[\]]+");

The quote should work, too. I updated my answer with a C# sample.

doesn't matter. the quote was passed as \x26amp; I'll just have to replace

@RaghavKhunger: Correct, I hit the wrong key when posting this. You have to escape ] and not [.
