Regular Expressions question

[Guest]

hi,

How can I verify a valid phone number contain 0-9 and characters ( ) -
and whitespace.

for example:

(416) 424-1234 or 416- 424-1234 or 4164241234

how can i use from Regular Expressions (C#)?

thank you,
monica

One way would be :
([() -]*[0-9]){10,}

- any of the characters '(', ')', space and '-', zero or more times
- followed by a single (!) digit
- and the whole thing repeated at least 10 times

One way would be :
([() -]*[0-9]){10,}

- any of the characters '(', ')', space and '-', zero or more times

Hi Monica,
Have a look at RegExBuddy.
It has a section that generates C# code for the regular expression that you
are generating.

The following tools are very helpful in writing and testing regular
expressions
