style is not a combination ofNumberStyles.AllowHexSpecifierandNumberStyles.HexNumbervalues. Remarks The TryParse(String, NumberStyles, IFormatProvider, UInt16%) method is like theParse(String, NumberStyles, IFormatProvider)method, except that it does not throw an exception if the conversi...
Binary format specifier (B) The binary ("B") format specifier converts a number to a string of binary digits. This format is supported only for integral types and only on .NET 8+. The precision specifier indicates the minimum number of digits desired in the resulting string. If required,...
The pattern in the format parameter consists of one or more custom format specifiers from the Custom Date and Time Format Strings table, or a single standard format specifier, which identifies a predefined pattern, from the Standard Date and Time Format Strings table. If you do not use da...
