RSCG – Enhanced.GetTypes
 
 

Generating list of PUBLIC classes that implements an interface

This is how you can use Enhanced.GetTypes .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Enhanced.GetTypes" Version="1.0.0" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using GetTypesForInterface;

Console.WriteLine("Hello,World!");
foreach (var type in ProjectTypes.GetIPersonTypes())
{
    Console.WriteLine(type.Name);
}

using Enhanced.GetTypes.Annotation;

namespace GetTypesForInterface;
public partial class ProjectTypes
{
    [DerivedTypes(typeof(IPerson))]
    public  static partial IEnumerable<Type> GetIPersonTypes();
}

namespace GetTypesForInterface;
internal interface IPerson
{
    public string Name { get; set; }
}

namespace GetTypesForInterface;
public class Student : IPerson
{
    public string Name { get; set; } = "";
}
    

namespace GetTypesForInterface;
public class Teacher:IPerson
{
    public string Name { get; set; } = "";
}

The code that is generated is

// <auto-generated />
namespace GetTypesForInterface
{
    partial class ProjectTypes
    {
        public static partial System.Collections.Generic.IEnumerable<System.Type> GetIPersonTypes()
        {
            yield return typeof(GetTypesForInterface.Student);
            yield return typeof(GetTypesForInterface.Teacher);
            yield break;
        }
    }
}
