Webservice ignores cultureinfo settings of application

Question

I have a webapplication with some forms which are posted to a webservice-method. The json-post is done by the jquery $.ajax method. Although my cultureinfo is set to nl-NL, my webmethod throws an error "10,00 is not a valid value for Decimal.", when posting the values of my form. The same goes for datetimes which have a dutch notation.

It seems like the .net serializer ignores the global culture settings. When i change '10,00' to '10.00' the post is accepted by the webmethod.

We've been struggling with this subject for a while now, couldn't find anything usefull on SO and Google myself. So any help on this matter would be very nice!

Answer 1

So basically this is done due this peace of code:

// No exponent, may or may not have a decimal (if it doesn't it couldn't be parsed into Int32/64)
            decimal dec;
            if (decimal.TryParse(input, NumberStyles.Number, CultureInfo.InvariantCulture, out dec)) {
                // NumberStyles.Number: AllowLeadingWhite, AllowTrailingWhite, AllowLeadingSign,
                //                      AllowTrailingSign, AllowDecimalPoint, AllowThousands
                return dec;
            }

So the only option is to replace the , with the . and surrender to the English supremacy.
