Phone Number String Manipulation

Chicago75

Help..
I am using the String.format() method and getting the following error...

An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll
Additional information: Input string was not in a correct format.

Here is the line of the code causing it...

strResult = String.Format("{^d-d{3}-d{3}-d{4}}", hpformato)

The "hpformato" is Dimmed as String. I don't know why this is not working..Help

I believe the String.Format does not support regular expressions, at least natively. I suppose if you create your own format provider class it could work.

Try this versionfor formatting a phone number ...

strResult = String.Format("{0}-{1}-{2}", _
Left(hpformato, 3), _
Mid(hpformato, 4, 3), _
Right(hpformato, 4))
