如何在不使用 GroupBox 的情况下为单选按钮指定值并确定选定的单选按钮 [英] How can I give a radio button a value and determine the selected radio button without using a GroupBox

问题描述

我有一个包含几个单选按钮的表单，这些单选按钮假设代表不同的整数值.

I have a form with few radio buttons that suppose to represent different integer values.

1) 是否有内置方法可以将值放在单选按钮后面"?一个例子:

1) Is there a built-in way to put a value "behind" a radio button? an example:

RadioButton rad = new RadioButton();
rad.Value = 5; // This is what im trying to achieve.

2) 我有几个单选按钮在逻辑上相互关联，我想知道选择了哪个单选按钮(没有将它们放入 GroupBox 控件中)并获取该单选按钮的选定值.注意:我想迭代"这 3 个控件并获取选定的控件，而不是执行 3 个 IF 语句.一个例子:

2) I have few RadioButtons that are logically related to each other and i want to know which one was selected (without putting them inside a GroupBox control) and get the selected value for that RadioButton. note: I would like to "Iterate" these 3 controls and get the selected one instead of doing 3 IF statements. an example:

RadioButton radColor1 = new RadioButton();
RadioButton radColor2 = new RadioButton();
RadioButton radColor3 = new RadioButton();

// ...

RadioButton radSelected = ?? // Get selected Radio Button from the 3 above.
//here i can get to radSelected.Value

推荐答案

如果要为控件分配任意值，请使用其 Tag 属性:

If you want to assign an arbitrary value to the control, use its Tag property:

radColor1.Tag = 5;

但是为什么不能简单地使用 Checked 属性?

But why can't you simply use the Checked property?

if (radColor1.Checked)
    //do something
if (radColor2.Checked)
    //do something else
//...however many more you need to check

迭代...

foreach (Control c in this.Controls)
{
    if (c is RadioButton)
    {
        if (((RadioButton)c).Checked)
        //do something
    }
}
