Parsing numbers with double.TryParse strange behaviour

Question

Why would double.TryParse() with these settings not parse

double.TryParse("1.035,00",
NumberStyles.AllowCurrencySymbol | NumberStyles.AllowLeadingWhite | NumberStyles.AllowTrailingWhite |
NumberStyles.AllowDecimalPoint | NumberStyles.AllowLeadingSign,
GlobalSettings.Instance.DefaultCulture, out price);

where DefaultCulture is sl-SI (Slovenian), which has the dot . as digit grouping symbol and , as decimal point. The price remains 0 after the parse.

?

TryParse returns a bool that indicates if parsing the value succeeded or failed. For your example, TryParse returns false. So the cause for price being 0 is that the string couldn't be parsed. — dtb

I find it strange that some would vote close due to localization. If the problem was the culture then it would affect numerous cultures, all those that used comma as decimal separator, which is both the ISO standard and the representation used in most countries — Rune FS

You are missing NumberStyles.AllowThousands:

double.TryParse("1.035,00", NumberStyles.AllowCurrencySymbol | 
                            NumberStyles.AllowLeadingWhite | 
                            NumberStyles.AllowTrailingWhite |
                            NumberStyles.AllowDecimalPoint | 
                            NumberStyles.AllowLeadingSign | 
                            NumberStyles.AllowThousands,
                            GlobalSettings.Instance.DefaultCulture, out price);

This worked for me

double.TryParse("1.035,00",
NumberStyles.Any,
GlobalSettings.Instance.DefaultCulture, out price);

would anyone else advise on using NumberStyles.Any in a sense, if there are any potential problems with it?

As per MSDN Indicates that all styles except AllowHexSpecifier are used. This is a composite number style.
