Question

I know you can add an attribute to methods in C# like this,

ex1.

[HttpPost]
public void Method()
{
//code
}

Which means the attribute must be satisfied to run Method().

And I know you can stack attributes like this,

ex2.

[HttpPost]
[RequireHttps]
public void Method2()
{
 //More code
}

Which checks that both attribute1 ‘AND’ attribute2 are satisfied before you can use Method2().

But can you ‘OR’ Attributes? Something like this maybe?

ex3.

[HttpPost || RequireHttps]
public void Method3()
{
  //Even more code
}

So if either attribute is satisfied you can use Method3().

Edit: Sorry was under the impression Attributes where called Annotations. Fixed that.

Answer 1

Which means the annotation must be satisfied to run Method()

That is a misunderstanding.

The [HttpPost] attribute is a directive, this method will only match a Post request. It is not a ‘demand’ like a security check. Only some attributes work that way.

But when considering them as ‘requirements’ : they work independently so that will always result in AND behaviour.
