How to determine which radio button was selected in C# ASP.NET CORE MVC 5.0

Solution for How to determine which radio button was selected in C# ASP.NET CORE MVC 5.0
is Given Below:

I am wanting to check to see which radio button was selected from my Index.cshtml file and from there I would like to use a switch statement to set attributes to its object. I was reading up on how to do this but majority of them were for groups in a windows form but that would not apply to me since I am using a asp.net core 5.0 web mvc project.

In my Index.cshmtl I have the following:

....
<form action="@Url.Action("SecIndex", "Second")">

    <input type="radio" value="1" /><label>Valid</label>
    <input type="radio" value="2" /><label>Wrong</label>
    <input type="radio" value="3" /><label>InValid</label>
    <input type="submit" value="Address Validation" />

</form>

then in my HomeController, I have the following method:

        [HttpPost]
        public IActionResult ValidateAddress()
        {
            // if radio button was checked, perform the following var request.


            var check = ""; // this should be able to grab the label of the button that was selected

            switch (check)
            {
                case "Valid":
                   var request = new AddressRequest
                    {
                        StatusCode = 1,
                        Address = "2018 Main St New York City, NY, 10001"
                    };
                    break;
                case "Wrong":
                    var req = new AddressRequest
                    {
                        StatusCode = 2,
                        Address = "91 Apple City Galveston, TX, 77550"
                    };
                    break;
                case "Invalid":
                    var addressRequest = new AddressRequest
                    {
                        StatusCode = 3,
                        Address = "00000 Tree Ln, Miami FL 91041"
                    };
                    break;
            }

            return View();
        }

But I cannot seem to figure out how to allow variable check to perform a check to see which radio button was selected since this is a asp.net core 5.0 web mvc project and not a windows form. Is there a way to do this in this type of project?


UPDATE:

So I realized that I wanted to have the Value as it was before with numbers. So implementing the suggestion, I needed to still redirect the user to the method SecIndex in my Second controller. However, I still needed to grab the value of radio button that was selected. So I attempted to do return RedirectToAction("SecIndex"); but when I ran the program and hit the button to validate it gave me:

This page isn’t working. If the problem continues, contact the site owner.
HTTP ERROR 405

Did I do something incorrectly? the URI shows up as https://localhost:5443/Home/ValidateAddress?Status=1. Not I did select the first option, which should give me Status as 1. Not sure why it is returning that though.

Inside of my HomeController:

       [HttpPost]
        public IActionResult ValidateAddress(string validate)
        {
            // if radio button was checked, perform the following var request.

            switch (validate)
            {
                case "Valid":
                   var request = new AddressRequest
                    {
                        StatusCode = 1,
                        Address = "2018 Main St New York City, NY, 10001"
                    };
                    break;
                case "Wrong":
                    var req = new AddressRequest
                    {
                        StatusCode = 2,
                        Address = "91 Apple City Galveston, TX, 77550"
                    };
                    break;
                case "Invalid":
                    var addressRequest = new AddressRequest
                    {
                        StatusCode = 3,
                        Address = "00000 Tree Ln, Miami FL 91041"
                    };
                    break;
            }

            return RedirectToAction("SecIndex");
        }

    }

Home View... index.cshtml:

<form action="@Url.Action("ValidateAddress", "Home")">

    <input type="radio" value="1" name="Status"/><label>Valid</label>
    <input type="radio" value="2" name="Status"/><label>Wrong</label>
    <input type="radio" value="3" name="Status"/><label>InValid</label>
    <input type="submit" value="Address Validation" />

</form>

Give the radio buttons a common name and assign the label text to the value of the radio buttons.

change Index.cshmtl to :

<form method="post" action="/DemSecondo/ValidateAddress">
    <input type="radio" value="Valid" name="myRadio" /><label>Valid</label>
    <input type="radio" value="Wrong" name="myRadio" /><label>Wrong</label>
    <input type="radio" value="InValid" name="myRadio" /><label>InValid</label>
    <input type="submit" value="Address Validation" />
</form>

and change ValidateAddress action to :

[HttpPost]
public IActionResult ValidateAddress(string myRadio)
{
    switch (myRadio)
    {
        case "Valid":
          var request = new AddressRequest
          {
              StatusCode = 1,
              Address = "2018 Main St New York City, NY, 10001"
          };
          break;
        case "Wrong":
          var req = new AddressRequest
          {
              StatusCode = 2,
              Address = "91 Apple City Galveston, TX, 77550"
          };
          break;
        case "Invalid":
          var addressRequest = new AddressRequest
          {
              StatusCode = 3,
              Address = "00000 Tree Ln, Miami FL 91041"
          };
          break;
     }

     return RedirectToAction("SecIndex");
}
