Question

I have a child class of AuthorizeAttribute named CheckArticleExistence.

I would like to set an attribute using the parameter that I receive in the action. Like this:

[CheckArticleExistence(Id=articleId)]
public ActionResult Tags(int articleId)
{
...
}

I want to use the articleId to check if that article exists in the database, and if it doesn’t I can trigger something different using the OnAuthorization method.

Is there any way?
Thanks.

I think You can get the articleId from the AuthorizationContext, so you don’t need to pass it as a property of the attribute.

You can just do:

[CheckArticleExistence]
public ActionResult Tags(int articleId)
{
...
}
