Using NumberStyles to parse numbers in C# .NET Part 3

In the previous post we looked at some more values in the NumberStyles enumeration. In this finishing post we’ll look at some more compact enumeration values and how you can pass in your own number format provider for customised and culture-independent solutions.

We’ve seen that you can combine the NumberStyles enumeration values like here:

string rawNumber = "$(14)";
int parsedNumber = int.Parse(rawNumber, NumberStyles.AllowParentheses | NumberStyles.AllowCurrencySymbol);

Using NumberStyles to parse numbers in C# .NET Part 2

In the previous post we looked at some basic usage of the NumberStyles enumeration. The enumeration allows to parse other representations of numeric values.

Occasionally negative numbers are shown with a trailing negative sign like this: “13-“. There’s a solution for that:

string number = "13-";
int parsed = int.Parse(number, NumberStyles.AllowTrailingSign);

“parsed” will be -13 as expected.

Using NumberStyles to parse numbers in C# .NET Part 1

There are a lot of number formats out there depending on the industry we’re looking at. E.g. negative numbers can be represented in several different ways:

• -14
• (14)
• 14-
• 14.00-
• (14,00)

…and so on. Accounting, finance and other, highly “numeric” fields will have their own standards to represent numbers. Your application may need to parse all these strings and convert them into proper numeric values. The static Parse method of the numeric classes, like int, double, decimal all accept a NumberStyles enumeration. This enumeration is located in the System.Globalization namespace.
