使用数组将多个参数(无线电)从视图传递到控制器 [英] Passing multi parameters (radio) from view to controller using array

问题描述

我想在不使用Model的情况下，将55到100个可能在视图中为假或真的项目发布到我的控制器.这是我在Razor View中的代码:

I would like to post between 55 and 100 items which could be false or true from view to my controller without using Model. This is my code in Razor View:

@using(Html.BeginForm("User","User",FormMethod.Post,new{enctype="multipart/form-data"}))
    {

        <input type="radio" name="answer1">Choice one</input>
        <input type="radio" name="answer1">Choice two</input>
        <input type="radio" name="answer2">Choice three</input>
        <input type="radio" name="answer2">Choice four</input>

    ....

    <input type="radio" name="answer55">Choice fifty five</input>
    <input type="radio" name="answer55">Choice fifty six</input>

    <button type="submit">Send</button>
                                   }

控制器:

[HttpPost]
public async Task<ActionResult> User(Array....)
{
return view();}

如何使用数组将所有参数(单选按钮)发送到控制器.感谢您的所有解决方案.

How can I send all of parameters (radio buttons) using an array to my controller. I appreciate all your solutions.

推荐答案

在视图中:要使数组起作用，请按以下格式命名单选按钮，以使模型绑定起作用

In View :For Arrays to work, name the Radio buttons in format as below for model binding to work

@using (Html.BeginForm("Index", "Home")) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary()
    <input type="radio" name="param[0]" value="one" >
    <input type="radio" name="param[0]" value="two" >
    <input type="radio" name="param[1]" value="three" >
    <input type="radio" name="param[1]" value="four" >
    <input type="radio" name="param[2]" value="five" >
    <input type="radio" name="param[2]" value="six" >
  <input type="submit" value="submit" />
}

在Post ActionMethod中:

In Post ActionMethod :

 [HttpPost]       
 public ActionResult Index(string[] param)
                { //
    }

然后您将在action方法中获取param数组中的值. 您可以根据需要设置任意数量的单选按钮， ModelBinder将负责绑定.

then you will get the value in param array in the action method. You can have as many number of Radio buttons as you wish & ModelBinder will take care of the binding.
