Reflection to Get `Parent` Object [duplicate]

Answer 1

Please don't actually do this...

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Reflection;
using System.Threading;

public class Program
{
    public static void Main()
    {
        var xx = B.GetParentType();
    }
}

public class A
{
    public B b { get; set; }
}

public class B
{
    public static List GetParentType()
    {
        var q = from t in Assembly.GetExecutingAssembly().GetTypes()
                where t.IsClass && t.GetProperties().Any(p => p.PropertyType == typeof(B))
                select t;
        return q.ToList();
    }
}
