C#中的反射：获取类直接实现的接口并排除继承的上级接口

using System;
using System.Linq;
using System.Collections.Generic;

public interface IBase { }
public interface IDerived : IBase { }
public interface IOther { }

public class MyClass : IDerived, IOther { }

public class Program
{
    public static void Main()
    {
        var directInterfaces = GetDirectlyImplementedInterfaces(typeof(MyClass));
        
        foreach (var iface in directInterfaces)
        {
            Console.WriteLine(iface.Name);
        }
    }

    public static List<Type> GetDirectlyImplementedInterfaces(Type type)
    {
        // Get all interfaces implemented by the class
        var allInterfaces = type.GetInterfaces();
        
        // Create a set of all inherited interfaces
        var inheritedInterfaces = new HashSet<Type>(allInterfaces.SelectMany(i => i.GetInterfaces()));
        
        // Direct interfaces are those that are in allInterfaces but not in inheritedInterfaces
        var directInterfaces = allInterfaces.Where(i => !inheritedInterfaces.Contains(i)).ToList();
        
        return directInterfaces;
    }
}
