Question

这是在 Windows窗体应用程序

中

应用程序如下所示：

RADIO1 text = 1
RADIO2 text = 2
RADIO3 text = 3
RADIO4 text = 3

当我按下名为button1的按钮时，它会像这样随机出现：

RADIO2 text = 2
RADIO1 text = 1
RADIO4 text = 4
RADIO3 text = 3

我尝试过这样的事情：

List<string> list = new List<string>{"1","2","3","4"};

public void ShuffleText()
{
  var rand = new Random();
  var shuffledText = list.OrderBy(x=>rand.Next(list.Count)).ToList();
  var radioButtons = new[]{radioButton1,radioButton2, radioButton3, radioButton4};

  for(int i = 0; i < radioButtons.Length;i++)
  {
    radioButtons[i].Text = shuffledText[i];
  }
}

但是，正如你所看到的，这只会改变radioButton的文本，我不希望按钮改变，因为它是我正在创建的测验，我不希望示例答案在顶部radioButtons一直都在。

Answer 1

也许您应该更多地查看组件的位置，而不仅仅是文本属性

EDIT;

List<string> list = new List<string>{"1","2","3","4"};
List<int> Locations new List<int>{100,200,300,400};
var r1 = new RadioButton();
var r2 = new Radiobutton();
var r3 = new RadioButton();
var r4 = new RadioButton();

var buttons = new[]{r1,r2,r3,r4};

var rand = new Random();
var shuffledText = list.OrderBy(x=>rand.Next(list.Count)).ToList();
var ShuffledButtons = Locations.OrderBy(x=> rand.Next(locations.Count)).ToList();

for(int i = 0; i < radioButtons.Length;i++)
{
    radioButtons[i].Text = shuffledText[i];
    radioButtons[i].Location.Y = shuffledButtons[i];
    radioButtons[i].Location.X = 50;
}

EDIT2：前面的代码会将您的radiobutton随机化为您的文本。

RB1 = 1
RB3 = 2
RB2 = 4
RB4 = 3

Answer 2

您可以在单击按钮上创建动态单选按钮，并在父控件中动态添加控件。

您还可以将表格布局控制放在单选按钮上方，并根据随机生成的数字更改单元格位置。

Answer 3

你可以这样做：

List<Point> list = new List<Point>{radioButton1.Location,radioButton2.Location,radioButton3.Location,radioButton4.Location};
// Rest of the code remains the same
var shuffledLocation = list.OrderBy(x=>rand.Next(list.Count)).ToList();
for(int i = 0; i < radioButtons.Length;i++)
   radioButtons[i].Location= shuffledLocation[i];

C＃ - 按下按钮，使4个单选按钮改变位置
