GetOnInherit

Finds types that inherit from a base class or implement an interface. The method scans the provided assemblies and returns every type where typeof(T).IsAssignableFrom(type) is true.

Use this method when building discovery-based registration, diagnostics, or metadata tooling. The returned sequence can include interfaces, abstract classes, and the base type itself, so filter the result when only concrete implementations should be used.

Usage

using System.Reflection;
using AlmightyShogun.Utils;

IEnumerable<Type> commandTypes = ApplicationUtils.GetOnInherit<ICommand>(
    Assembly.GetExecutingAssembly()
);

foreach (Type commandType in commandTypes.Where(type => type is { IsInterface: false, IsAbstract: false }))
{
    Console.WriteLine(commandType.FullName);
}

Parameters

assemblies: Assembly[]
Assemblies to scan. When omitted, the calling assembly is scanned.
Default: []

Returns

A sequence of types assignable to T from the selected assemblies.

Type signature

public static IEnumerable<Type> GetOnInherit<T>(
    params Assembly[] assemblies
);
