Core Concepts & Domain
This codebase demonstrates the usage of generics to achieve flexibility and reusability within the context of mathematical operations. The code primarily revolves around the concept of IParseable, which serves as a central interface for objects that can be parsed from strings. This approach enables the code to work with different data types without explicit type checking, leading to improved maintainability and extensibility.
IParseable
The IParseable interface defines a single method, Parse, which takes a string and a format provider as input and returns an object of the implementing type. This interface allows for the parsing of diverse data types, such as Roman Numerals, Integers, or custom data structures.
Example:
public class RomanNumeral : IParseable
{
private readonly int _value;
private RomanNumeral(int value)
{
_value = value;
}
public static RomanNumeral Parse(string s, IFormatProvider? provider)
{
// Implement Roman numeral parsing logic here
// ...
return new RomanNumeral(value);
}
// ... other methods ...
}
Parsing and Invariant Culture
The InvariantParse method, defined in the Program.cs file, leverages the IParseable interface to provide a generic way to parse strings. It uses CultureInfo.InvariantCulture to ensure consistent parsing regardless of the user’s locale settings.
Example:
static T InvariantParse<T>(string s)
where T : IParseable
{
return T.Parse(s, CultureInfo.InvariantCulture);
}
Usage and Example
The code demonstrates the application of IParseable through an example using Name and RomanNumeral classes. The Blah method showcases how to parse various data types using the InvariantParse method.
Example:
void Blah()
{
var name = InvariantParse<Name>("Fred");
var number = InvariantParse<RomanNumeral>("IV");
Console.WriteLine(name);
Console.WriteLine(number);
}
