Question

In the view, for example, in “_Layout.cshtml”

How to get the controller/action which called this view?

After found the controller/action name, then how to get the list of the attribute it has? Or test if it has an attribute?

Thanks.

@ViewContext.Controller will give you the controller instance that returned this view. Once you get the instance, you get the type and once you have the type you get into Reflection to get the attributes this type is decorated with. Writing a custom HTML helper to perform this job could be worth it:

public static class HtmlExtensions
{
    public static bool IsDecoratedWithFoo(this HtmlHelper htmlHelper)
    {
        var controller = htmlHelper.ViewContext.Controller;
        return controller
            .GetType()
            .GetCustomAttributes(typeof(FooAttribute), true)
            .Any();
    }
}
