當聲明類型不同時，UpdateModel不起作用

Question

這是我所問的代碼示例。

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(); 
    } 

如果我在運行時確定模型類型，更新模型的最佳方法是什麼？

要解決在運行時（雖然不是很明顯，爲什麼你需要，從您發佈的），然後使用dynamic：

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