Question

这是我要问的代码示例。

    public ActionResult Action()
    {
        object person = new Person(); //It works if i replace object with Person
        UpdateModel(person); //this does not update person because of "object" declaring type

        return View();
    }

如果我在运行时确定模型类型，更新模型的最佳方法是什么？

Answer 1

要在运行时解决（虽然不明显为什么你需要，从你发布的内容），然后使用dynamic：

dynamic person = new Person();   // resolves at runtime -- no point in doing this,
                                 // since the type is known at compile time anyway

当声明类型不同时，UpdateModel不起作用
