如何确定在 C# ASP.NET CORE MVC 5.0 中选择了哪个单选按钮

Question

我想查看 select 从我的 Index.cshtml 文件中编辑了哪个单选按钮，然后我想从那里使用 switch 语句为其对象设置属性。我正在阅读有关如何执行此操作的信息，但其中大多数是针对 windows 形式的组，但这不适用于我，因为我使用的是 asp.net 核心 5.0 web mvc 项目。

在我的 Index.cshmtl 中，我有以下内容：

....
<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>

然后在我的HomeController中，我有以下方法：

        [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();
        }

但我似乎无法弄清楚如何允许变量 check 执行检查以查看哪个单选按钮被 selected，因为这是一个 asp.net 核心 5.0 web mvc项目而不是 windows 表格。有没有办法在这种类型的项目中做到这一点？

更新：

所以我意识到我想拥有与以前一样的数值。因此，在实施该建议时，我仍需要将用户重定向到我的 Second 控制器中的方法 SecIndex。但是，我仍然需要获取 selected 的单选按钮的值。所以我试图做 return RedirectToAction("SecIndex"); 但是当我运行程序并点击按钮验证它给了我：

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

我是不是做错了什么？ URI 显示为 https://localhost:5443/Home/ValidateAddress?Status=1。不是我做了 select 第一个选项，它应该给我 Status 作为 1。不知道为什么它会返回那个。

我的HomeController里面：

       [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>

Answer 1

为单选按钮指定一个通用名称，并将标签文本分配给单选按钮的值。

将 Index.cshmtl 更改为：

<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>

并将 ValidateAddress 操作更改为：

[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");
}
