如何使用asp.net mvc视图返回404

Question

我如何实现以下功能？

我的控制器:

if (something == null)
{         
     //return the view with 404 http header
     return View();          
}

  //return the view with 200 http header
  return View();

Answer 1

写吧

Response.StatusCode = 404;

在返回视图之前.

Answer 2

if (something == null)
{         
   return new HttpNotFoundResult(); // 404
}
else
{
   return new HttpStatusCodeResult(HttpStatusCode.OK); // 200
}

Answer 3

if (something == null)
{         
    Response.StatusCode = (int)HttpStatusCode.NotFound;
    return View();          
}

//return the view with 200 http header
return View();

Answer 4

您应该将TrySkipIisCustomErrors属性设置Response为true.

public ActionResult NotFound()
{
    Response.StatusCode = 404;
    Response.TrySkipIisCustomErrors = true;
    return View();
}
