c# - How can I pair objects to radio buttons? -

i'm working on small form app, , have "paired" radio buttons lists in common class. purpose of turn on/off corresponding list

public class mytype {     public radiobutton button { get; set; }     public listbox list { get; set; } } 

i proceed create these pairs through loop inside array

for (int = 0; < broj_botuna; i++) {     thearray[i] = new mytype(); } 

i use common event handler radio buttons:

private void test_checkedchanged(object sender, eventargs e) {     var xx = sender radiobutton;     //do stuff     positioninarray = array.indexof(thearray, xx); } 

except last line of code "xx" should of type "mytype" , not "radiobutton" managed retrieve.

so tell me how reference "radiobutton" "mytype"? or there better alternative?

you can use array.findindex like:

var positioninarray = array.findindex(thearray, b => b.button == xx);
