How to know which RadioButton that is selected?

Question

Hi I am working on an assignment from the Head First C# book. I have three radio buttons (joeRButton bobRButton and alRButton). I also has an array with an instance of an class named Guy. Every Guy (Joe Bob and Al) has an instance of this class i.e. Guy[] guy = new Guy[3]. So far so good! I want to know which radio button is checked when I press a button so I can do some stuff. However I don't want to do if joeRButton.checked = true DO THIS if bobRButton.checked = true DO THIS I want it do be more dynamic. Each radio button is assigned to their instance (guy[0] = new Guy() { Name = Joe Cash = 100 MyLabel = joeBox MyRadioButton = joeRButton }) Can anyone help me with this?

Only one radio button can be checked at any given time so you can have a global variable that is set in the radio buttons click event then using the variable you could do switch(whichPerson) { case 1: //Do Stuff break case 2: //Do more stuff break; }
