ClassEnumerator

This project is a small class with the only purpose to provide the coder with a list of classes implemmenting a specific interface. This is done by asking for classes that match a specific Interface or classes that inherit from a specific class. The whole idea is to make it easier to use plugins or solutions of that kind.

  • The main reason I made it a nuget was to show my students how to create and publis nugets. *

Getting Started

You can either use the Nuget manager in Visual Studio, or install it from the package-manager. For more information see docs.microsoft.com.

Prerequisites

If you need a list of classes without having to code a control to create an instance of each of them.

for(int i=0; i<MyStuff.Count; i++)
    Console.WriteLine($"{i:00} {MyStuff[i].Name}");

Console.Write("Select a topic: ");
var input = Console.ReadLine();
_ = int.TryParse(input, out var choice);

ITopic topic;
switch(choice())
{
    case 0: topic=new Topic0(); break;
    // A long list of cases follows....
}

Installing

You can use the Nuget manager in visual studio or simply type

install-package MMPClassEnumerator

Using the nuget

To get a list of instansiated classes that match your interface, you type

var listOfStuff = EnumerateClasses<IStuff>.GetClassesByInterface();

If you only want the name of the classes that match your interface, you type

var listOfStuff = EnumerateClasses<IStuff>.ListClassesByInterface();

To list the classes you could use

ListOfStuff.ForEach(i => Console.WriteLine(i.Name));

The nuget provides you with four methods

// Gets instances of classes that match the given parent class
GetClassesByInheritance<T>()

// Gets instances of classes that match the given Interface
GetClassesByInterface<T>()

// Gets definitons of classes that match the given parent class
ListClassesByInheritance<T>()

// Gets definitons of classes that match the given Interface
ListClassesByInterface<T>()

Usage example

var listOfStuff = EnumerateClasses<IStuff>.GetClassesByInterface();
for(int i=0; i<MyStuff.Count; i++)
    Console.WriteLine($"{i:00} {MyStuff[i].Name}");```

Console.Write("Select a topic: ");
var input = Console.ReadLine();
_ = int.TryParse(input, out var choice);

ITopic topic=MyStuff[choice];

Other example, to list all classes in a project

var lst = EnumerateClasses<object>.GetClassesByInheritance().ToList();
lst.ForEach(i => Console.WriteLine(" class " + i.GetType().Name + "()"));

Deployment

The deployment to a nuget is triggered by scripts on GitHub after PR to the main repository.
