使用反射在dll中获取某些基类型的所有类

namespace MyDLL
{
    public class MyClass1
    {
        // ...
    }

    public class MyClass2
    {
        // ...
    }

    public class MyClass3 : MyClass1
    {
        // ...
    }

    public class MyClass4 : MyClass2
    {
        // ...
    }
}

using System;
using System.IO;
using System.Reflection;

namespace ReflectionExample
{
    class Program
    {
        static void Main(string[] args)
        {
            string dllPath = @"C:\path\to\MyDLL.dll";
            Assembly assembly = Assembly.LoadFrom(dllPath);

            Type baseType = typeof(MyDLL.MyClass1);
            Type[] derivedTypes = GetDerivedTypes(assembly, baseType);

            Console.WriteLine($"Derived types of {baseType.FullName}:");
            foreach (Type derivedType in derivedTypes)
            {
                Console.WriteLine(derivedType.FullName);
            }
        }

        static Type[] GetDerivedTypes(Assembly assembly, Type baseType)
        {
            List<Type> derivedTypes = new List<Type>();

            foreach (Type type in assembly.GetTypes())
            {
                if (type.IsSubclassOf(baseType))
                {
                    derivedTypes.Add(type);
                }
            }

            return derivedTypes.ToArray();
        }
    }
}
