int.Parse and NumberStyles.AllowParentheses

Hi,

Just a quick question: How come that using int.Parse("(20),
NumberStyles.AllowParenthesis" ); returns a negative value?

I would definetly expect that call to return something positive.

Thanks, Bernhard.

If you look at standard numbering, in apps like Excel, negative numbers can
take one of the following formats:

-20
(20)

The same methodology has been put into .NET.

Parenthesizing negative numbers is an accounting principle, that can be
utilized in the .NET Framework

This still does not make sense because you do not expect something general as
int.Parse()/NumberStyles.* to be accounting specific.

But thanks for the explanation. I can now see where it originates from.
Thanks, B.
