Question

I’m having issue converting this string to a decimal. I tried to follow the documentation here with no luck: Decimal.TryParse Method

string stringVal = "-(3434343434.00)";

NumberStyles style = NumberStyles.AllowDecimalPoint | NumberStyles.AllowThousands |
    NumberStyles.AllowParentheses | NumberStyles.AllowLeadingSign;

CultureInfo culture = CultureInfo.CreateSpecificCulture("en-US");

decimal value;
bool parseSuccess = decimal.TryParse(stringVal, style, culture, out value);

parseSuccess is returning false.

Answer 1

You have both () and a - sign in your string. This is incorrect and is why your string doesn’t parse.

See the documentations for AllowParentheses:

AllowParentheses: Indicates that the numeric string can have one pair of parentheses enclosing the number. The parentheses indicate that the string to be parsed represents a negative number.
