推荐答案

好吧，您尚未说明尝试过的内容，尝试时出现的问题是什么.

看看有关单选按钮如何分组的这些文章:
Gropu单选按钮 [如何对RadioButton进行分组 [

Well, you have not stated what you have tried and where was the issue when you tried it.

Have a look at these article on how radio buttons are grouped:
Gropu Radio Button[^]
How to group RadioButtons[^]

They are more than enough to understand the logic which can be used for coding your scenario.

UPDATE:
Ok. Fine, try this: (it''s in C# that I am writing):

// Do this for getting checked status of all radio buttons
// Similar approch can be done to RESET an uncheck them all
for(int i=0;i<myGroupBox.Controls.Count;i++)
{
   RadioButton rb= (RadioButton)myGroupBox.Controls[i];
   if(rb.checked==true)
   {
      // do whatever
      // use break; if needed
      // increase a counter if you want number
   }
}

遍历组框的子级，并检查它们是否是1)单选按钮和2)未选中的.

Iterate over the children of the groupboxes and check if they are 1) radiobuttons and 2) unchecked.
