You can try implementing good old for loop. If you want to create radiobuttons being stacked vertically :

  //TODO: provide the desired value here
  int numberOfRadioButtons = 7;

  //TODO: Put desired values here
  int left = 15;
  int top = 25;
  int height = 50;

  for (int i = 0; i < numberOfRadioButtons; ++i) {
    RadioButton button = new RadioButton() {
      Parent = myGroupBox,
      Location = new Point(left, top + height * i),
      Text = $"RadioButton # {i}",

      // If you insist on setting size manually, uncomment the lines below
      //AutoSize = false,
      //Size = new Size(200, height),
    };

    // button is created; you can use it, say, to assign event handler:
    //button.Click += MyRadioButtonClick;
  }

Edit: You can use Linq to get checked RadioButton :

  using System.Linq;

  ...

  // Either checked rudio button or null if none of radio button is checked
  RadioButton chosen = myGroupBox
    .Controls
    .OfType<RadioButton>()
    .FirstOrDefault(button => button.Checked);
