如何基于公认的HTTP动词来重载ASP.NET MVC操作？

[ActionName]

[HttpGet]
[ActionName(\"Foo\")]
public ActionResult GetMe()
{
   ...
}

[HttpPut]
[ActionName(\"Foo\")]
public ActionResult PutMe()
{
   ...
}

[HttpDelete]
[ActionName(\"Foo\")]
public ActionResult DeleteMe()
{
   ...
}

[HttpPost]
[ActionName(\"Foo\")]
public ActionResult PostMe()
{
   ...
}

ActionName

[HttpGet]
public ActionResult ActionName() {...}

[HttpPost, ActionName(\"ActionName\")]
public ActionResult ActionNamePost() {...}

[HttpGet]
public ActionResult ActionName() {...}

[HttpPost]
public ActionResult ActionName(string aParameter) {...}

            string httpMethod = Request.HttpMethod.ToUpperInvariant();

            switch (httpMethod)
            {
                case \"GET\":
                    return GetResponse();

                case \"POST\":
                    return PostResponse();

                default:
                    throw new ApplicationException(string.Format(\"Unsupported HttpMethod {0}.\", httpMethod));
            }
