Get controller and action name from AuthorizationHandlerContext object

Question

Hi I have a custom requirement handler with accepts the AuthorizationHandlerContext context parameter

When i debug, i can see that the context object contains Context.Resources.ActionDescription.ActionName

But when writing the code i cant go beyond Context.Resources

Seems the lower levels are not exposed. I want to get the action name and controller name that called the handler. How do i do this?

Answer 1

var mvcContext = context.Resource as AuthorizationFilterContext;
var descriptor = mvcContext?.ActionDescriptor as ControllerActionDescriptor;
if (descriptor != null)
{
    var actionName = descriptor.ActionName;
    var ctrlName = descriptor.ControllerName;      
}

Answer 2

After upgrading to dotnet 5, the solution I was successfully using from Carsten above stopped working. The following workaround now works for me:

var routeValues = (context.Resource as HttpContext).Request.RouteValues;
var controllerName = routeValues["controller"].ToString();
var actionName = routeValues["action"].ToString();

Note this should include some null checks etc. the above is a barebones example.
