如何在C#中收集具有一般类型的静态类的所有“实例”？

using System;
using System.Reflection;
using System.Collections.Generic;

public static class StaticClass1
{
    public static void Method1()
    {
        Console.WriteLine("StaticClass1.Method1");
    }
}

public static class StaticClass2
{
    public static void Method2()
    {
        Console.WriteLine("StaticClass2.Method2");
    }
}

public class Program
{
    public static void Main()
    {
        List<Type> staticClasses = new List<Type>();

        Assembly assembly = Assembly.GetExecutingAssembly();
        Type[] types = assembly.GetTypes();

        foreach (Type type in types)
        {
            if (type.IsSealed && type.IsAbstract && type.GetMethods().Length > 0)
            {
                staticClasses.Add(type);
            }
        }

        foreach (Type staticClass in staticClasses)
        {
            Console.WriteLine(staticClass.Name);
        }
    }
}
