当过滤器在没有单词的情况下映射时，所需的ActionFilterAttribute的“ Attribute”结尾是什么

Question

I've created a new mvc 4 project (razor engine) and I'm not sure of one thing.

There's a filter:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute
{
...
}

and there's a controller using that filter:

[InitializeSimpleMembership]
public class AccountController : Controller
{
...
}

Why using InitializeSimpleMembership instead of InitializeSimpleMembershipAttribute is working properly?

Answer 1

17.1.1 Attribute usage :

The example

[Simple] class Class1 {...}
[Simple] interface Interface1 {...}

shows several uses of the Simple attribute. Although this attribute is defined with the name SimpleAttribute, when this attribute is used, the Attribute suffix may be omitted , resulting in the short name Simple. Thus, the example above is semantically equivalent to the following:

[SimpleAttribute] class Class1 {...}
[SimpleAttribute] interface Interface1 {...}

Edit: For a extra clarity, in case you were wondering about the naming convention, 17.1 Attribute classes :

By convention, attribute classes are named with a suffix of Attribute. Uses of an attribute may either include or omit this suffix.
