I would throw a 404 exception and create a custom exception filter that return a not found page for 404 errors. The built-in HandleErrorfilter doesn't handle 404 errors.
我会抛出一个 404 异常并创建一个自定义异常过滤器，该过滤器为 404 错误返回一个未找到的页面。内置HandleError过滤器不处理 404 错误。
if (something == null)
{
throw new HttpException(404, "Not found")
}
return View();

You should set TrySkipIisCustomErrorsproperty of Responseas true.
您应该将TrySkipIisCustomErrors属性设置为Responseas true。
public ActionResult NotFound()
{
Response.StatusCode = 404;
Response.TrySkipIisCustomErrors = true;
return View();
}
