extracting digits from string in c#
<p>I'm writing a json deserializer for a phone object.</p>

<p>One of the properties is the phone number. In my database, I store the number as a string of digits.</p>

<p>I have the string called <code>IncomingClientJsonPhoneCandidate</code> and I'm writing a loop that goes through each character of the string and adds the value to a string builder if the character passes a byte.TryParse.</p>

<p>I'm wondering if there's a better way to do this.
Thanks for your suggestions.</p>
