推荐答案

ModelBinding 是ASP.NET MVC用来创建强类型对象的机制（或填充primitive-型参数）从输入流（通常是一个HTTP请求）。

ModelBinding is the mechanism ASP.NET MVC uses to create strongly-typed objects (or fill primitive-type parameters) from the input stream (usually an HTTP request).

例如，考虑这个人模型：

public class Person
{
     public string Name { get; set; }
     public int Age { get; set; }
}

现在，你有一些动作在某些控制器这是期待人类型作为参数：

Now, you have some Action in some Controller that's expecting a Person type as a parameter:

public class HomeController : Controller
{
      public ActionResult EditPersonDetails(Person person)
      {
          // ...
      }
}

的模型文件夹然后负责填补人参数为您服务。默认情况下，通过咨询 ValueProviders 收集，并要求在（受约束）模型中每个属性的值做的。

The Model-Binder is then responsible to fill that person parameter for you. By default it does it by consulting the ValueProviders collection and asking for the value of each property in the (to be bound) model.
