C#求取径向列表选项的有效方法

Question

我正在努力减少工作量/不必要的线，现在我将以2000条线结束。

HTML

    <input runat="server" type="radio" id="radial9" value="9" name="test"/>
    <label for="radial9" class="right"></label>
    <input runat="server" type="radio" id="radial8" value="8" name="test"/>
    <label for="radial8" class="left"></label>
    <input runat="server" type="radio" id="radial7" value="7" name="test"/>
    <label for="radial7" class="right"></label>
    <input runat="server" type="radio" id="radial6" value="6" name="test"/>
    <label for="radial6" class="left"></label>
    <input runat="server" type="radio" id="radial5" value="5" name="test"/>
    <label for="radial5" class="right"></label>
    <input runat="server" type="radio" id="radial4" value="4" name="test"/>
    <label for="radial4" class="left"></label>
    <input runat="server" type="radio" id="radial3" value="3" name="test"/>
    <label for="radial3" class="right"></label>
    <input runat="server" type="radio" id="radial2" value="2" name="test"/>
    <label for="radial2" class="left"></label>
    <input runat="server" type="radio" id="radial1" value="1" name="test"/>
    <label for="radial1" class="right"></label>
    <input runat="server" type="radio" id="radial0" value="0" name="test"/>
    <label for="radial0" class="left"></label>

然后，查找选定的径向按钮的重复工作开始：

    int selected;

    if (radial0.Checked)
    {
        selected = Convert.ToInt32(radial0.Value);
    }
    else if (radial1.Checked)
    {
        selected = Convert.ToInt32(radial1.Value);
    }
    else if (radial2.Checked)
    {
        selected = Convert.ToInt32(radial2.Value);
    }
    else if (radial3.Checked)
    {
        selected = Convert.ToInt32(radial3.Value);
    }
    else if (radial4.Checked)
    {
        selected = Convert.ToInt32(radial4.Value);
    }
    else if (radial5.Checked)
    {
        selected = Convert.ToInt32(radial5.Value);
    }
    else if (radial6.Checked)
    {
        selected = Convert.ToInt32(radial6.Value);
    }
    else if (radial7.Checked)
    {
        selected = Convert.ToInt32(radial7.Value);
    }
    else if (radial8.Checked)
    {
        selected = Convert.ToInt32(radial8.Value);
    }
    else if (radial9.Checked)
    {
        selected = Convert.ToInt32(radial9.Value);
    }
    else
    {
        Label1.Text = "You selected invalid";
    }

我是说..。应该有一种更简单的方法，数组应该使这种方法更好，但是我找不到一种方法.(我需要将输入ID转换成一个参数值)，我会有一个非常简洁的解决方案，我可以发送或制作id吗？

static int getRadialChecked(string name)
{
    for (int i = 0; i < 10; i++)
    {
        if ((name + i).Checked)
        {
            return Convert.ToInt32((name + i).Value);
        }
    }

    return 0;
}

    int value = getRadialChecked("radial");

Answer 1

将无线电按钮包装在容器控件中

    <div id="radioSelections" runat="server">
        <input runat="server" type="radio" id="radial9" value="9" name="test"/>
            <label for="radial9" class="right"></label>
            <input runat="server" type="radio" id="radial8" value="8" name="test"/>
            <label for="radial8" class="left"></label>
        ....
    </div>

使用LINQ搜索单选按钮列表以获取所选控件，然后获取值。

        var checkedButton = radioSelections.Controls.OfType<HtmlInputRadioButton>().FirstOrDefault(b=>b.Checked);
        var selected = checkedButton?.Value;

Answer 2

更改函数的数据类型(添加System.Web.UI.HtmlControls;)

static int getRadialChecked(HtmlInputRadioButton[] values)
{
    for (int i = 0; i < 10; i++)
    {
        if (values[i].Checked)
        {
            return Convert.ToInt32(values[i].Value);
        }
    }
    return -1;
}

-

HtmlInputRadioButton[] radialArray = { radial0, radial1, radial3, radial4, radial5, radial6, radial7, radial8, radial9 };
int value = getRadialChecked(radialArray);
