C# Regex remove everything except \d+, one, nine and decimal point

How can i do something like this.

new Regex("([^\d+]|[^one]|[^nine]|[^,])").Replace("Fi10An,fONEy,Onineo", "");

I would get this:

10,one,nine

But i would get a empty string with my wrong regex above.

Thank you in Advance!

Try doing the opposite: match what you need and then take it from the string. For example:

Regex.Matches("Fi10An,fONEy,Onineo", @"(\d+|one|nine|,)", RegexOptions.IgnoreCase)

And then combine the matches into one string. This would be the easiest and the clearest solution.
