c# - Get controller, action, parameter in Filter attribute -

this question has answer here:

• how controller , action name in onactionexecuting? 5 answers

i want build custom filter attribute added controller level. how can current controller, action , parameter names being invoked?

example: if issues post request to: https://localhost:443/api/users/delete/3

how can in attribute (and not talking url parsing here)

• controller = users
• action = delete
• id = 3

@kamo has provided duplicate question first parts, id, use .actionarguments, eg:

 public override void onactionexecuting(httpactioncontext actioncontext)  {      var id = (int)actioncontext.actionarguments["id"]; 

actionarguments dictionary, iterate using linq if arg optional or writing generic handler actions (eg log every action parameters/arguments)

this provided framework, after binding, match action's parameters - if binding not match action filterabbtribute won't kick in if applied @ controller level. can't use finding why routes don't match actions.
