GET and POST to same Controller Action in ASP.NET MVC

Question

I\'d like to have a single action respond to both Gets as well as Posts. I tried the following

[HttpGet]
[HttpPost]
public ActionResult SignIn()


        

Answer 1

[HttpGet]
public ActionResult SignIn()
{
}

[HttpPost]
public ActionResult SignIn(FormCollection form)
{
}

Answer 2

This is possible using the AcceptVerbs attribute. Its a bit more verbose but more flexible.

[AcceptVerbs(HttpVerbs.Get|HttpVerbs.Post)]
public ActionResult SignIn()
{
}

More on msdn.

Answer 3

Actions respond to both GETs and POSTs by default, so you don't have to specify anything:

public ActionResult SignIn()
{
    //how'd we get here?
    string method = HttpContext.Request.HttpMethod;
    return View();
}

Depending on your need you could still perform different logic depending on the HttpMethod by operating on the HttpContext.Request.HttpMethod value.
