GET and POST methods with the same Action name in the same Controller [duplicate]

Answer 1

Today I was checking some resources about the same question and I got an example very interesting.

It is possible to call the same method by GET and POST protocol, but you need to overload the parameters like that:

@using (Ajax.BeginForm("Index", "MyController", ajaxOptions, new { @id = "form-consulta" }))
{
//code
}

The action:

[ActionName("Index")]
public async Task<ActionResult> IndexAsync(MyModel model)
{
//code
}

By default a method without explicit protocol is GET, but in that case there is a declared parameter which allows the method works like a POST.

When GET is executed the parameter does not matter, but when POST is executed the parameter is required on your request.

Answer 2

To answer your specific question, you cannot have two methods with the same name and the same arguments in a single class; using the HttpGet and HttpPost attributes doesn't distinguish the methods.

To address this, I'd typically include the view model for the form you're posting:

public class HomeController : Controller
{
    [HttpGet]
    public ActionResult Index()
    {
        Some Code--Some Code---Some Code
        return View();
    }

    [HttpPost]
    public ActionResult Index(formViewModel model)
    {
        do work on model --
        return View();
    }

}
