c# - how do I get Controller data from ModelValidatorContext in ASP.NET Core -

i have custom model validator:

public class myvalidationattribute : attribute, imodelvalidator {     public ienumerable<modelvalidationresult> validate(modelvalidationcontext context) {     ...     } } 

let's say, purposes of validation need data controller. not expert in reflection voodoo, can some data controller:

var descriptor = context.actioncontext.actiondescriptor controlleractiondescriptor; 

or

var typeinfo = descriptor.controllertypeinfo; 

but if have variable in controller, say, repository of dbcontext passed via di (although doubt if important) - how can access variable validator?

note: simplified use case mcve purposes. realize brittle way go , there better way validation when need do remote validation. use case different.
