Question & Answer :
Backmost successful RC1, I would bash this:
[HttpPost] national IActionResult Station([FromBody]drawstring thing) { attempt{ // ... } drawback(Objection e) { instrument fresh HttpStatusCodeResult((int)HttpStatusCode.InternalServerError); } }
Successful RC2, location nary longer is HttpStatusCodeResult, and location is thing I tin discovery that lets maine instrument a 500 kind of IActionResult.
Is the attack present wholly antithetic for what I’m asking? Bash we nary longer attempt-drawback successful Controller codification? Bash we conscionable fto the model propulsion a generic 500 objection backmost to the API caller? For improvement, however tin I seat the direct objection stack?
From what I tin seat location are helper strategies wrong the ControllerBase people. Conscionable usage the StatusCode methodology:
[HttpPost] national IActionResult Station([FromBody] drawstring thing) { //... attempt { DoSomething(); } drawback(Objection e) { LogException(e); instrument StatusCode(500); } }
You whitethorn besides usage the StatusCode(int statusCode, entity worth) overload which besides negotiates the contented.
