I have a different requirement and it is :
I need to validate a phone number field.
It may or may not be a US phone number.
The constraints are :
***********************
# It should accept any number of numbers
# any number of - hyphens
# and one + symbol
# no other characters and alphabets are allowed
Thanks in advance

There are some awesome phone number examples out there....I am sure you can
find one that matches most phone numbers in most regions :)...but darn, that
has to be a HUGE pattern :P
Here's one that does U.S. and regional telephone numbers ... including
extentions (copied and slightly modified from
http://javascript.about.com/library/blre.htm).
----
/// <summary>
/// Determines whether the specified text is a valid phone number.
/// </summary>
/// <param name="Text">The text to check.</param>
/// <returns>
/// Returns <see langword="true" /> if the <paramref name="Text" />
/// argument is a valid phone number, otherwise returns <see
/// langword="false" />.
/// </returns>
private static bool IsPhoneNumber(string Text)
{
const string PHONE_PATTERN =
@"^((\+\d{1,3}(-| )?\(?\d\)?(-| )?\d{1,3})|(\(?\d{2,3}\)?))" +
@"(-| )?(\d{3,4})(-| )?(\d{4})(\s*(x|ext)\d{1,5}){0,1}$";
return System.Text.RegularExpressions.Regex.IsMatch(
Text,
PHONE_PATTERN
);
}
