ASP.NET MVC绑定属性的方法而不是参数 [英] ASP.NET MVC Bind Attribute on Method instead of Parameter

问题描述

我知道，你可以这样做：

I'm aware that you can do this:

public ActionResult DoSomething([Bind(Exclude = "CreationDate")] Item item)
{ /*...*/ }

不过，我发现，你还可以将绑定与属性的方法，例如之上。

However, I found that you can also attach that Bind attribute on top of the method, e.g.

[Bind(Exclude = "CreationDate")] 
public ActionResult DoSomething(Item item)
{ /*...*/ }

这是否有相同的效果吗？如果你绑定到多个参数？

Does this have the exact same effect? What if you bind to more than one parameter?

推荐答案

第二种形式是我见过更常见的之一。据我所知，这两种形式做同样的事情。

The second form is the one that I have seen more commonly. To my knowledge, both forms do exactly the same thing.

排除选项采用一个逗号分隔的属性列表。排除列表根本不包括从结合的一个或多个参数;其对剩余的参数没有影响

The Exclude option takes a comma-separated list of attributes. The Exclude list simply excludes one or more parameters from binding; it has no effect on the remaining parameters.

例如：

[Bind(Exclude="ID, Name")]
