Yoichi,
Thank you so much for the responses. After some experimentation, it looks like I was looking for the “&” operator:
System.Text.RegularExpressions.Regex.Match(QuoteTxt,String.Join("|",testArray)).Value & System.Text.RegularExpressions.Regex.Match(QuoteTxt, "\d{1,3}").Value
Thank you again for your responses!
