Using Loops

sorry for my bad English!

i have a custom class:

 public class playerData {
         public string name;
         public NetworkPlayer player;
         public Transform Prefab;
         
         public bool isReady = false;
     }

and a list:

 public List<playerData> players = new List<playerData>();

and i want to call a function if every item isReady in the List. I t$$anonymous$$nk i should use loop but i don't know what.
