Returning Empty ActionResult

asp.net-mvcactionresultbad-request

提问by Maxim V. Pavlov

I may encounter situations, when I need to just return bad request result.

我可能会遇到一些情况,当我只需要返回错误的请求结果时。

For example, there is a call to MVC 3 site's controllers action, but the required parameter is missing in a request uri.

例如,有一个对 MVC 3 站点的控制器操作的调用,但请求 uri 中缺少必需的参数。

What do I return in response. I know I can do this:

我返回什么作为回应。我知道我可以这样做:

Response.StatusCode = (int)HttpStatusCode.BadRequest;
return Content(string.Empty);

Is this the correct way for the above described situation?

这是上述情况的正确方法吗?

Your solution will work OK, but more clear way will be using HttpStatusCodeResultclass, like this:

您的解决方案可以正常工作,但更清晰的方法是使用HttpStatusCodeResult类,如下所示:

return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
