ModelBindingis the mechanism ASP.NET MVC uses to create strongly-typed objects (or fill primitive-type parameters) from the input stream (usually an HTTP request).
ModelBinding是 ASP.NET MVC 用于从输入流（通常是 HTTP 请求）创建强类型对象（或填充原始类型参数）的机制。
For example, consider this Personmodel:
例如，考虑这个Person模型：
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
}
Now, you have some Actionin some Controllerthat's expecting a Persontype as a parameter:
现在，你有一些Action在某些Controller该公司预计，一个Person类型作为参数：
public class HomeController : Controller
{
public ActionResult EditPersonDetails(Person person)
{
// ...
}
}
The Model-Binderis then responsible to fill that personparameter for you. By default it does it by consulting the ValueProviderscollection and asking for the value of each property in the (to be bound) model.
该Model-Binder将负责填补person参数为您服务。默认情况下，它通过查询ValueProviders集合并询问（待绑定）模型中每个属性的值来实现。
