c# - Force two ActionFilter attributes to be used in conjunction with one another -

i had 3 authorization attributes contained code check content being requested exists. decided avoid repeating myself in each, creating new attribute called quizexistsattribute.

i wish run before other authorization attributes.

now have attribute, wish ensure original attributes using, aren't used without new attribute - because want check made before else.

my other authorization attributes rely on logic of quizexistsattribute being performed are:

• activequiztakersessionatrribute
• authorizequizadminattribute

so in code using them so:

/// <summary> /// start of quiz /// </summary> /// <param name="urlid"></param> /// <returns></returns> [quizexists] // check quiz exists [activequiztakersession] // check have active session quiz [httpget] public actionresult quizquestion(string urlid) {     // code here after checks } 

is there way enforce activequiztakersession used injunction (and following) quizexists attribute?

you can set order in each attribute executed:

[quizexists(order = 1)] // check quiz exists [activequiztakersession(order = 2)] // check have active session quiz [httpget] 

here's reference further:

order property of actionfilter, lowest greatest or vice versa?
