将Listbox绑定到对象列表的最简单方法是什么？

参考:如何将动态用作通用？

public void CheckEntity(int entityId, string entityType = null)
{
 dynamic AnyObject = Activator.CreateInstance("Assembly","Assembly.Models.DbModels." + entityType).Unwrap();
 CheckWithInference(AnyObject, entityId);
}

private static void CheckWithInference<T>(T ignored, int entityId) where T : class
{
 Check<T>(entityId);
}

private static void Check<T>(int entityId) where T : class
{
 using (var gr = new GenericRepository<T>())
 {
 }
}

这进入了CheckEntity(16,"Container");.第一行运行后,使用调试器检查时AnyObject变为空白Assembly.Models.DbModels.Container.如果var AnyType = AnyObject.GetType();使用,则AnyType显示为Assembly.Models.DbModels.Container.但是,当调用CheckWithInference(AnyObject, entityId);使得异常被抛出时.

鉴于以下计划:

using System;
using System.Collections.Generic;

namespace ConsoleApplication49
{
    using FooSpace;

    class Program
    {
        static void Main(string[] args)
        {
            IEnumerable<FooBase> foos = FooFactory.CreateFoos();

            foreach (var foo in foos)
            {             
                HandleFoo(foo);
            }
        }

        private static void HandleFoo(FooBase foo)
        {
            dynamic fooObject = foo;
            ApplyFooDefaults(fooObject);
        }

        private static void ApplyFooDefaults(Foo1 foo1)
        {
            foo1.Name = "Foo 1";

            Console.WriteLine(foo1);
        }

        private static void ApplyFooDefaults(Foo2 foo2)
        {
            foo2.Name        = "Foo 2";
            foo2.Description = "SomeDefaultDescription";

            Console.WriteLine(foo2);
        }

        private static void ApplyFooDefaults(Foo3 foo3)
        {
            foo3.Name    = "Foo 3"; …
