How do I use regex to remove brackets and spaces

See more:

C#7.0

I have created a barcode validator, and some of the barcodes we get may be in a format such as (03) 15645 132156464
I would like to remove only spaces and brackets. I do not want to remove anything else, such as Barcode pending

Although I can probably use string.Replace, I want to give Regex a go.

What I have tried:

So far I have found I can do the following...

string sampleBarcode = "(03) 15645 132156464";

// Remove spaces
sampleBarcode = Regex.Replace(sampleBarcode, @"\s+", "");

// Remove opening brackets
sampleBarcode = Regex.Replace(sampleBarcode, @"\(", "");

// Remove closing brackets
sampleBarcode = Regex.Replace(sampleBarcode, @"\)", "");

What I cannot figure out, is how to do this with just the one Regex statement.

Any help is appreciated.
