Using HTTP status codes with custom messages outside of controller

Question

I'm trying to return HTTP codes that would contain a custom message outside of a controller.

For example, in a controller I can have

return BadRequest("Invalid");

Inside a regular method I tried the following code

return Microsoft.AspNetCore.Http.StatusCodes.Status400BadRequest("Invalid");

But I get the following message

"Non-invocable 'StatusCodes.Status400BadRequest' cannot be used like a method"

Is there anyway I can return HTTP codes with custom messages outside of a controller?

As the exception message says, Microsoft.AspNetCore.Http.StatusCodes.Status400BadRequest is a const int, not a function. You can't thus invoke it with ( and ). — Wiktor Zychla

BadRequest("Invalid") returns an BadRequestObjectResult instance.

In similar way, you can return an instance of this class from your code via

return new BadRequestObjectResult("Invalid");
