Char Const Type Arguments

Const type arguments (also called const type args) are types used to pass constant & static values to generics through type parameters. These values are available at compile-time and can be used in static contexts, such as static constructors, static fields, and static methods. This can provide enhanced type safety, compile-time polymorphism, performance improvements, and more.

You can use types in the ConstTypeArgs.Chars namespace for passing ASCII character values as const type arguments.

The following is a simple Hello World example to demonstrate how this works:

using ConstTypeArgs.Chars;

public static class Foo<TChar>
   where TChar: K_Char
{
   private static readonly char Separator = TChar.Value;

   public static void Output(string[] items)
   {
       foreach (var item in items)
           Console.Write($"{item}{Separator}");
   }
}

// Elsewhere
var helloWorld = new string[] { "Hello", "World!" };

Foo<Comma>.Output(helloWorld);       // Output: Hello,World!
Foo<Slash>.Output(helloWorld);       // Output: Hello/World!
Foo<Semicolon>.Output(helloWorld);   // Output: Hello;World!
Foo<VerticalBar>.Output(helloWorld); // Output: Hello|World!

You can create new domain-specific char const type arguments like so:

public sealed class ListSeparator  : Char<Comma>;
public sealed class TableSeparator : Char<VerticalBar>;
