ASP.NET MVC 4，抛出HttpException VS回报的HTTPStatus codeResult？

问题描述

我开发一个RESTful服务，我要回400所有不支持的URL。

I am developing a RESTful service and I want to return 400 for all unsupported URLs.

我的问题是的我应该选择方法1在方法2，反之亦然。

//method 1
public ActionResult Index()
{
    //The url passed is unsupported
    throw new HttpException(400, "Bad Request");
}

这一次似乎是更好的？

//method 2
public ActionResult Index()
{
    //The url passed is unsupported
    return new HttpStatusCodeResult(HttpStatusCode.BadRequest, "Bad Request");
}

推荐答案

第二似乎更好，因为它不涉及其是在一个微成本相比于第一实施例的异常投掷。

The second seems better as it doesn't involve exception throwing which comes at a micro-cost compared to the first example.
